Data Science for Wildland Fire Research

In recent years, wildfire has gone from an infrequent and distant news item to a centerstage isssue spanning many consecutive weeks for urban and suburban communities. Frequent wildfires are changing everyday lives for California in numerous ways -- from public safety power shutoffs to hazardous air quality -- that seemed inconceivable as recently as 2015. Moreover, elevated wildfire risk in the western United States (and similar climates globally) is here to stay into the foreseeable future. There is a plethora of problems that need solutions in the wildland fire arena; many of them are well suited to a data-driven approach.

Seminar Series

Data Science for Physics

Astrophysicists and particle physicists at Stanford and at the SLAC National Accelerator Laboratory are deeply engaged in studying the Universe at both the largest and smallest scales, with state-of-the-art instrumentation at telescopes and accelerator facilities

Data Science for Economics

Many of the most pressing questions in empirical economics concern causal questions, such as the impact, both short and long run, of educational choices on labor market outcomes, and of economic policies on distributions of outcomes. This makes them conceptually quite different from the predictive type of questions that many of the recently developed methods in machine learning are primarily designed for.

Data Science for Education

Educational data spans K-12 school and district records, digital archives of instructional materials and gradebooks, as well as student responses on course surveys. Data science of actual classroom interaction is also of increasing interest and reality.

Data Science for Human Health

It is clear that data science will be a driving force in transitioning the world’s healthcare systems from reactive “sick-based” care to proactive, preventive care.

Data Science for Humanity

Our modern era is characterized by massive amounts of data documenting the behaviors of individuals, groups, organizations, cultures, and indeed entire societies. This wealth of data on modern humanity is accompanied by massive digitization of historical data, both textual and numeric, in the form of historic newspapers, literary and linguistic corpora, economic data, censuses, and other government data, gathered and preserved over centuries, and newly digitized, acquired, and provisioned by libraries, scholars, and commercial entities.

Data Science for Linguistics

The impact of data science on linguistics has been profound. All areas of the field depend on having a rich picture of the true range of variation, within dialects, across dialects, and among different languages. The subfield of corpus linguistics is arguably as old as the field itself and, with the advent of computers, gave rise to many core techniques in data science.

Data Science for Nature and Sustainability

Many key sustainability issues translate into decision and optimization problems and could greatly benefit from data-driven decision making tools. In fact, the impact of modern information technology has been highly uneven, mainly benefiting large firms in profitable sectors, with little or no benefit in terms of the environment. Our vision is that data-driven methods can — and should — play a key role in increasing the efficiency and effectiveness of the way we manage and allocate our natural resources.

Ethics and Data Science

With the emergence of new techniques of machine learning, and the possibility of using algorithms to perform tasks previously done by human beings, as well as to generate new knowledge, we again face a set of new ethical questions.

The Science of Data Science

The practice of data analysis has changed enormously. Data science needs to find new inferential paradigms that allow data exploration prior to the formulation of hypotheses.

End-to-end projects involve real-world problems which you solve using the 6 stages of the data science life cycle:

• Business understanding
• Data understanding
• Data preparation

Here’s how to execute a data science project from end to end in more detail.

First, you define the business questions, requirements, and performance measurement. After that, you collect data to answer these questions. Then come the cleaning and preparation processes to get the data ready for exploration and analysis. These are the understanding stages.

But we’re not done yet.

Next comes the data preparation process. It involves the preprocessing and engineering of the features to prepare for the modeling step. Once that’s done, you can train the models on the prepared data. Depending on the task you are working on, you can do one of two things:

• Deploy the model on a live server and integrate it into a mobile or web application; then, monitor it and iterate again if needed, or
• Build dashboards based on the insights extracted from the data and the modeling step.

That wraps up the data science life cycle. Before you start working, you need some ideas for a data science project.

For starters, select a domain you are interested in. You can choose one that fits your educational background or previous work experience. This will give you a head start as you will know the field.

After that, you need to explore the common problems in this domain and how data science can solve them. Finally, choose a case study and formulate the business questions. Only then can you apply the life cycle we discussed above.

Now, let’s get started with a few project ideas.

Marine life has a significant impact on our planet, providing food, oxygen, and biodiversity. Unfortunately, 90% of the large fish are gone primarily as a result of overfishing . In addition, many major fisheries notice increases in illegal fishing, undermining the efforts to conserve and manage fish stocks.

Detecting fishing activities in the ocean is a crucial step in achieving sustainability. It’s also an excellent big data project to add to your portfolio.

Identifying whether a vessel is fishing illegally and where this activity is likely to occur is a major step in ending illegal, unreported, and unregulated (IUU) fishing. However, monitoring the oceans is costly, time-consuming, and logistically difficult.

To overcome these challenges, we must improve the ability to detect and predict illegal fishing. This can be done using classification machine learning models to recognize and trace illegal fishing activity by collecting and processing GPS data from ships, as well as other pieces of information. The classification algorithm can distinguish these ships by type, fishing gear, and fishing behaviors.

• Collect the fishing watch dataset
• Perform data exploration to understand it better
• Perform engineering to extract features from the data
• Train classification models to categorize the fishing activity
• Deploy the trained model on a live server and integrate it into a web application
• Finish by monitoring the model in production and iterating

Deployed model running in a live server and used within a web service or mobile application to predict illegal fishing in real time.

Project Overview

Flawed products can result in substantial financial losses, so defect detection is crucial in manufacturing. Although human detection systems are still the traditional method employed, computer vision techniques are more effective.

In this example, we build a system to detect defects in metallic objects or surfaces during different phases of the production processes.

The types of defects can be aesthetic, such as stains, or potentially damaging the product’s functionality, such as notches, scratches, burns, lack of rectification, bumps, burrs, flatness, lack of thread, countersunk, rust, or cracks.

Since the appearance of metallic surfaces changes substantially with different lighting, defects are hard to detect even using computer vision. For this reason, lighting is a crucial component in solving such types of data science problems. Otherwise, the methodology of this project is standard.

• Collect the metal surface defects dataset
• Data cleaning and exploration
• Feature extraction
• Train models for defects detection and classification
• Deploy the model into production on an embedded system

A deployed model on an embedded system that can detect and classify metallic surface defects in different conditions and environments.

20 Data Science Topics and Areas

It is no doubt that data science topics and areas are some of the hottest business points today.

We collected some basic and advanced topics in data science to give you ideas on where to master your skills.

In today’s landscape, businesses are investing in corporate data science training to enhance their employees’ data science capabilities.

Data science topics also are hot subjects you can use as directions to prepare yourself for data science job interview questions.

1. The core of data mining process

This is an example of a wide data science topic.

What is it?

Data mining is an iterative process that involves discovering patterns in large data sets. It includes methods and techniques such as machine learning, statistics, database systems and etc.

The two main data mining objectives are to find out patterns and establish trends and relationship in a dataset in order to solve problems.

The general stages of the data mining process are: problem definition, data exploration, data preparation, modeling, evaluation, and deployment.

Core terms related to data mining are classification, predictions, association rules, data reduction, data exploration, supervised and unsupervised learning, datasets organization, sampling from datasets, building a model and etc.

2. Data visualization

Data visualization is the presentation of data in a graphical format.

It enables decision-makers of all levels to see data and analytics presented visually, so they can identify valuable patterns or trends.

Data visualization is another broad subject that covers the understanding and use of basic types of graphs (such as line graphs, bar graphs, scatter plots , histograms, box and whisker plots , heatmaps.

You cannot go without these graphs. In addition, here you need to learn about multidimensional variables with adding variables and using colors, size, shapes, animations.

Manipulation also plays a role here. You should be able to rascal, zoom, filter, aggregate data.

Using some specialized visualizations such as map charts and tree maps is a hot skill too.

3. Dimension reduction methods and techniques

Dimension Reduction process involves converting a data set with vast dimensions into a dataset with lesser dimensions ensuring that it provides similar information in short.

In other words, dimensionality reduction consists of series of techniques and methods in machine learning and statistics to decrease the number of random variables.

There are so many methods and techniques to perform dimension reduction.

The most popular of them are Missing Values, Low Variance, Decision Trees, Random Forest, High Correlation, Factor Analysis, Principal Component Analysis, Backward Feature Elimination.

4. Classification

Classification is a core data mining technique for assigning categories to a set of data.

The purpose is to support gathering accurate analysis and predictions from the data.

Classification is one of the key methods for making the analysis of a large amount of datasets effective.

Classification is one of the hottest data science topics too. A data scientist should know how to use classification algorithms to solve different business problems.

This includes knowing how to define a classification problem, explore data with univariate and bivariate visualization, extract and prepare data, build classification models, evaluate models, and etc. Linear and non-linear classifiers are some of the key terms here.

5. Simple and multiple linear regression

Linear regression models are among the basic statistical models for studying relationships between an independent variable X and Y dependent variable.

It is a mathematical modeling which allows you to make predictions and prognosis for the value of Y depending on the different values of X.

There are two main types of linear regression: simple linear regression models and multiple linear regression models.

Key points here are terms such as correlation coefficient, regression line, residual plot, linear regression equation and etc. For the beginning, see some simple linear regression examples .

6. K-nearest neighbor (k-NN) 

N-nearest-neighbor is a data classification algorithm that evaluates the likelihood a data point to be a member of one group. It depends on how near the data point is to that group.

As one of the key non-parametric method used for regression and classification, k-NN can be classified as one of the best data science topics ever.

Determining neighbors, using classification rules, choosing k are a few of the skills a data scientist should have. K-nearest neighbor is also one of the key text mining and anomaly detection algorithms .

7. Naive Bayes

Naive Bayes is a collection of classification algorithms which are based on the so-called Bayes Theorem .

Widely used in Machine Learning, Naive Bayes has some crucial applications such as spam detection and document classification.

There are different Naive Bayes variations. The most popular of them are the Multinomial Naive Bayes, Bernoulli Naive Bayes, and Binarized Multinomial Naive Bayes.

8. Classification and regression trees (CART)

When it comes to algorithms for predictive modeling machine learning, decision trees algorithms have a vital role.

The decision tree is one of the most popular predictive modeling approaches used in data mining, statistics and machine learning that builds classification or regression models in the shape of a tree (that’s why they are also known as regression and classification trees).

They work for both categorical data and continuous data.

Some terms and topics you should master in this field involve CART decision tree methodology, classification trees, regression trees, interactive dihotomiser, C4.5, C5.5, decision stump, conditional decision tree, M5, and etc.

9. Logistic regression

Logistic regression is one of the oldest data science topics and areas and as the linear regression, it studies the relationship between dependable and independent variable.

However, we use logistic regression analysis where the dependent variable is dichotomous (binary).

You will face terms such as sigmoid function, S-shaped curve, multiple logistic regression with categorical explanatory variables, multiple binary logistic regression with a combination of categorical and continuous predictors and etc.

10. Neural Networks

Neural Networks act as a total hit in the machine learning nowadays. Neural networks (also known as artificial neural networks) are systems of hardware and/or software that mimic the human brain neurons operation.

The above were some of the basic data science topics. Here is a list of more interesting and advanced topics:

11. Discriminant analysis

12. Association rules

13. Cluster analysis

14. Time series

15. Regression-based forecasting

16. Smoothing methods

17. Time stamps and financial modeling

18. Fraud detection

To boost ocean research, some scientists are turning to superyachts

by Laurel Chor, Bloomberg News

For almost two years, Robert Brewin collected data from the bow of a superyacht as it sailed pristine waters from the Caribbean Sea to the Antarctic Ocean.

The Archimedes, a 222-foot "adventure" yacht then owned by the late hedge funder James Simons, boasts a gym, a jacuzzi and an elevator. But between 2018 and 2020, Brewin was concerned only with the boat's Sea-Bird Scientific Solar Tracking Aiming System, installed to measure light reflecting off of the water. A senior lecturer at the UK's University of Exeter, Brewin and his colleagues were analyzing microplankton—microscopic organisms at the base of the marine food chain—by studying the ocean's color. The Sea-Bird's readouts helped them verify satellite imagery.

Brewin's was not your typical superyacht itinerary, but he is one of hundreds of scientists to have used an adventure yacht—also known as expedition or explorer yachts—to conduct research on the ocean. In a paper published in Frontiers in Remote Sensing , Brewin and his co-authors touted the potential of "harnessing superyachts" for science, concluding that "reaching out to wealthy citizen scientists may help fill [research capability] gaps."

It's a view shared—and being pushed—by the Yacht Club of Monaco and the Explorers Club, a New York City-based organization focused on exploration and science (of which, full disclosure, I am a member). In March, the groups co-hosted an environmental symposium that included an awards ceremony for yacht owners who "stand out for their commitment to protecting the marine environment ." The Archimedes won a "Science & Discovery" award.

"If a yacht is operating 365 days a year, rather than having it sit idle it'd be much better for it to contribute a positive return through science and conservation," says Rob McCallum, an Explorers Club fellow and founder of US-based EYOS Expeditions, which runs adventure yacht voyages.

EYOS charters yachts from private owners for its excursions, and is a founding member of Yachts for Science, a four-year-old organization that matches privately owned yachts with scientists who need time at sea. (Other members include yacht builder Arksen, media firm BOAT International, and nonprofits Nekton Foundation and Ocean Family Foundation.) Yachts for Science will enable about $1 million worth of donated yacht time this year, McCallum says, a figure he expects to hit $15 million by 2029.

"There's a personal satisfaction that we are contributing to something that is bigger than us," says Tom Peterson, who co-owns an insurance underwriting company in California and has what he jokingly refers to as a "mini superyacht."

Every year for the past decade, Peterson has donated about 15 to 20 days of time and fuel on the 24-meter Valkyrie to scientists, who he takes out himself as a licensed captain and former scuba dive operator. He often works with the Shark Lab at California State University Long Beach, and allows researchers to stay aboard for days at a time instead of having to constantly make the 1.5-hour trip to and from shore.

To link up with scientists, Peterson works with the International SeaKeepers Society, a Florida-based nonprofit that engages the yachting community to support ocean conservation and research. "The more we understand things about the ocean in general, the better we all are in the long run," he says.

When "superyacht" and "the environment" appear in the same sentence, it's usually in a different context. In 2019, one study estimated that a single 71-meter superyacht has the same annual carbon footprint as about 200 cars. In 2021, another paper found that superyachts were the single greatest contributor to the carbon footprint of 20 of the world's most prominent billionaires, accounting for 64% of their combined emissions.

"If you really want to respect the environment, you can just go surf," says Grégory Salle, a senior researcher at the French National Center for Scientific Research and author of the book Superyachts: Luxury, Tranquility and Ecocide. Salle is open to the idea that superyachts could be used to advance scientific research, but says it's contradictory for anyone to buy a superyacht and claim to be truly concerned about the environment.

McCallum says people who own adventure yachts tend to be younger than your standard superyacht owner, and have a particular interest in remote and pristine places. "They're not the sort of people that are content to just hang out in the Mediterranean or the Caribbean," he says. "Antarctica, the Arctic, the remote Indian Ocean, the remote Pacific Ocean, the Subantarctic islands… that's where you're going to find us delivering our services."

Explorer yachts aren't the only way scientists can reach those destinations, but demand for dedicated research vessels does outstrip available supply. The U.S. National Oceanic and Atmospheric Administration (NOAA), arguably the world's greatest collector of oceanographic data, has a fleet of 15 research and survey vessels for the use of its scientists.

Academic researchers can also apply to use the fleet, often at a subsidized rate. But scientists request roughly 15,000 to 20,000 days of boat time every year. In 2019, NOAA was able to fill just 2,300 of them, according to an internal study.

That gap is particularly problematic as the planet warms. Oceans provide services that scientists call "existentially important," producing more than half of the oxygen we breathe and serving as the world's largest carbon sink. They also absorb 30% of our carbon emissions and 90% of the excess heat generated by them.

G. Mark Miller, a retired NOAA Corps officer who was in charge of several of the agency's research vessels, has a different solution in mind when it comes to bolstering ocean research: smaller boats, fit for purpose. Superyachts can cost north of $500 million, he says, "why don't we build a hundred $5 million vessels and flood the ocean science community?"

After leaving NOAA, Miller in 2021 launched Virginia-based Greenwater Marine Sciences Offshore with a vision of building a global fleet of research vessels and offering their use at affordable prices. He says hiring a NOAA boat can cost scientists between $20,000 and $100,000 per day. GMSO plans to charge less than $10,000 a day for most missions. The company says it's close to acquiring its first three vessels.

Miller hopes his business model will help scientists conduct the work they need to—particularly in under-served regions like the Asia-Pacific—without worrying about getting a luxury yacht covered in "muddy worms, plankton goo, dead fish [and] whale snot." He describes yacht owners donating boat time to scientists as "better than nothing," and says it can help get regular people interested in science and exploration.

Christopher Walsh, captain of the Archimedes, says he and his crew love taking part in science initiatives, especially when there's an educational component. "I get a real thrill when we can stream to the classrooms—you can't imagine the enthusiasm the kids display," Walsh says. "That gives me a lot of hope for the future."

• Science and Technology Directorate
• Homeland Security Awards Contracts to Six Startups to Identify, Develop, and Implement Privacy-Enhancing Digital Wallets Technologies

News Release: Homeland Security Awards Contracts to Six Startups to Identify, Develop, and Implement Privacy-Enhancing Digital Wallets Technologies

For immediate release s&t public affairs , 202-286-9047.

Awardees will partner with DHS to meet Homeland Security mission needs.

WASHINGTON – The Department of Homeland Security (DHS)  Science and Technology Directorate  (S&T) announced that Credence ID, Hushmesh, Netis d.o.o., Procivis, SpruceID, and Ubiqu have each won a government contract to develop technologies that protect the privacy of individuals using digital versions of credentials issued for immigration and travel. These digital credential users, including immigrants and travelers, could eventually store their information in privacy-enhanced digital wallets. Since DHS interacts more frequently on a daily basis with the American public than any other federal agency or department, maintaining secure, confidential digital interactions will have a tremendous impact on the privacy, security and safety of residents across the country.

“DHS is the authoritative source of some of the most highly valued credentials issued by the U.S. Federal Government for cross-border travel, demonstrating employment eligibility, residency status and citizenship,” said Anil John, Technical Director of S&T’s Silicon Valley Innovation program (SVIP). “The capabilities developed under this solicitation will ensure that those credentials can be stored securely and verified properly while preserving the privacy of individuals using openly developed standards that are globally acceptable, highly secure, and accessible to all.”

“U.S. Citizenship and Immigration Services is the United States’ authoritative issuer of highly valued credentials related to citizenship and immigration. Supporting standards-based digital credentials and secure digital wallets for storing them enables us to meet our customer expectations of ease, convenience, privacy and security in an increasingly digital world,” said Jared X. Goodwin, Acting Chief Program Management and Data Division, Service Center Operations, U.S. Citizenship and Immigration Services (USCIS).

DHS provided the awards through its Privacy Preserving Digital Credential Wallets & Verifiers solicitation , which reflects the Department’s continued commitment to improving the delivery of its services in a way that both protects privacy and increases ease-of-use. The requirements included ensuring that DHS digital credential wallets and verifiers incorporated open, global standards that are not proprietary. These standards were established by the World Wide Web Consortium (W3C), a global standards development organization that manages the development of open standards ensuring interoperability, accessibility, internationalization, privacy and security. DHS participates as a W3C member to ensure DHS-relevant security and privacy criteria are incorporated into the standards development process.

S&T’s Silicon Valley Innovation Program  issued the solicitation in partnership with U.S. Citizenship and Immigration Services, U.S. Customs and Border Protection, and the DHS Privacy Office. It builds on the success and global adoption of the open, standards-based digital credentialing solutions developed under its previous Preventing Forgery & Counterfeiting of Certificates and Licenses topic call, which aimed to address paper-based credentialing susceptible to loss, destruction, and counterfeiting.

Selected through a highly competitive process, each awardee is eligible for up to $1.7 million across  four SVIP phases . The awardees of this first phase presented innovative solutions that have the potential to provide immediate impact to DHS:

• DHS S&T awarded $199,140 to Credence ID, an Oakland, California-based U.S. company , which specializes in standards-based identity verification and authentication solutions for in-person and online use. The company plans to adapt their existing hardware and software credential verifier implementations to support W3C VCDM and W3C DID standards, requiring a simple software update to existing hardware readers.  
• DHS S&T awarded $199,430 to Hushmesh, a Falls Church, Virginia-based U.S. company , to adapt their technology, the Mesh, incorporating built-in cryptographic security and universal zero trust.

Government innovation

Governments today must be able to adapt to changing environments, work in different ways, and find solutions to complex challenges. OECD work on public sector innovation looks at how governments can use novel tools and approaches to improve practices, achieve efficiencies and produce better policy results.

Key messages, innovation is a strategic function that must be integrated into broader public sector governance..

Innovation rarely happens by accident. Governments can increase innovation in the public sector through deliberate efforts using many different levers, from investments in skills or technology, to applying new policymaking methods or adapting existing processes. Our work helps governments assess their innovative capacity, providing practical and evidence-based steps to embed innovation in policymaking and administration. This means governments are better able to respond to changing environments and develop more impactful policies.

Behavioural science helps governments put people at the center of public policy.

Understanding cognitive biases, behavioural barriers, and social norms  is essential for the development of impactful policies and public uptake. Behavioural science is an interdisciplinary approach, providing insights that enable policymakers to design more effective and targeted policies that reflect actual human behaviour and decision-making. Our work encompasses research on context-specific behavioural drivers and barriers to support countries in the use of behavioural science from policy design to implementation and evaluation. Through the OECD Network of Behavioural Science Experts in Government, we further foster the exchange of best behavioural science practices and mutual learning.

Governments must anticipate, understand and prepare for the future as it emerges.

The nature of policy issues that governments are confronted by is volatile, uncertain, complex and often ambiguous. Governments need to consider a variety of scenarios and act upon them in real time. This requires a new approach to policymaking, one that is future and action oriented, involves an innovation function and anticipates the changing environment. By governing with anticipation and innovation, governments can prepare for what’s coming next. They can identify, test, and implement innovative solutions to benefit from future opportunities while reducing risk and enhancing resilience.

Innovation in public services unlocks efficiency, responsiveness and citizen satisfaction.

Innovating and digitalising public services can bring many benefits, including improving the quality, efficiency and effectiveness of services, enhancing equitable access and reducing administrative burdens. While it holds tremendous benefits for supporting the overall well-being and satisfaction of citizens and public trust in institutions, governments must ensure high standards of transparency and ethics, particularly when employing the use of data and artificial intelligence to improve or deliver public services. Our work is building towards an OECD Recommendation on the design of government services to effectively improve people's experiences including through life events and the development of more effective and equitable services.  

The public has a lack of confidence in public agencies adopting innovative ideas.

Governments must do better to respond to citizens’ concerns. Just fewer than one in four (38%, on average across OECD countries), feel that a public agency would be likely to adopt an innovative idea to improve a public service. Enhancing innovation capacity can strengthen resilience, responsiveness and trust in public institutions.

Confidence in governments’ adoption of innovative ideas is directly related to trust in civil servants.

People who say they are confident about innovation in a public office are more likely to trust civil servants. On average across OECD countries, the share of people who trust the civil service is equal to 70% among those who are confident about public sector innovation. This trust value is more than two times larger than among those who say that the public sector would not adopt innovative ideas.
