  • Teaching Rats To Drive Tiny Cars Helps Them Relax, Scientists Discover
    Researchers from the University of Richmond in Virginia used the vehicle-driving rodents to show that an enriched environment can improve cognitive function and help sharpen the ability to learn complex tasks. They also demonstrated that the mastery of a complicated skill can reduce levels of stress and help the rodents chill out...
  • Quantum Supremacy Using a Programmable Superconducting Processor
    Physicists have been talking about the power of quantum computing for over 30 years, but the questions have always been: will it ever do something useful and is it worth investing in? For such large-scale endeavors it is good engineering practice to formulate decisive short-term goals that demonstrate whether the designs are going in the right direction. So, we devised an experiment as an important milestone to help answer these questions. This experiment, referred to as a quantum supremacy experiment, provided direction for our team to overcome the many technical challenges inherent in quantum systems engineering to make a computer that is both programmable and powerful...

  • A Deep Active Learning System for Species Identification and Counting in Camera Trap Images
    In this paper, we focus not on automating the labeling of camera trap images, but on accelerating this process. We combine the power of machine intelligence and human intelligence to build a scalable, fast, and accurate active learning system to minimize the manual work required to identify and count animals in camera trap images. Our proposed scheme can match the state of the art accuracy on a 3.2 million image dataset with as few as 14,100 manual labels, which means decreasing manual labeling effort by over 99.5%...
  • Understanding Classification Thresholds Using Isocurves
    Your job as a data scientist isn’t done until you explain how to interpret the model and apply it. That means threshold selection for the business decision that motivated the model. As a data scientist, you might say…“A blog post about thresholds? It’s not even a data science problem, it’s a business problem.” And you would be right! Threshold selection lacks the appeal of say, generative adversarial networks. But it’s also where the rubber meets the road, where all the creative stuff you did with fancy algorithms interacts with real-world decision-making...
  • Improving long-form question answering by compressing search results
    A new method to improve the performance of long-form question answering (QA) systems by enabling them to search relevant text more efficiently. This method builds on Facebook AI’s work on long-form QA a natural language processing (NLP) research task where models must answer a natural language question, such as “What is Albert Einstein famous for?” by using the top 100 web search results...
  • CrossFit — A Young Men’s Game or Not
    Every year, the finest athletes compete in the Crossfit Games to win the title of “Fittest on Earth”. To kickstart this competition, the CrossFit community (or cult) participates in the Crossfit Opens where the fittest are selected. Typically perceived as a sport of the young due to the intensity of the workouts and heavy lifting involved. Despite that, the emphasis on functional fitness and community has attracted people of all ages, from kids to elderly. As a Crossfitter who is frequently gasping for air at the end of a workout with a buddy who is older, I was interested to find out if my situation was the norm...
  • How can I find Data Science Internships to strengthen my resume?
    There's lots of advice out there espousing the value of internships. We agree. Getting an internship (or more) under your belt can be a great way to build up practical experience and provide real-world examples of your work when it comes to applying for full-time roles. However, that's the theory. How about the practice? How should you go about finding internships? Who offers them? How can you source them?...

Training & Resources

  • Audio and Visual Quality Measurement using Fréchet Distance
    Since generative models have no “ground-truth,” evaluating their performance can be difficult. New quantitative metrics use the Fréchet distance between model and source distributions to evaluate the quality of generative audio and video. Learn more...
  • stacknn-core: The Successor to StackNN
    This library implements differentiable stacks and queues in PyTorch. It is a light-weight version of StackNN that is easier to install and optimized for faster training. The API is also straightforward...
