  • Rip van Winkle's Razor, a Simple New Estimate for Adaptive Data Analysis
    Can you trust a model whose designer had access to the test/holdout set? This implicit question in Dwork et al 2015 launched a new field, adaptive data analysis...This blog post concerns our new paper, which gives meaningful upper bounds on this sort of trouble for popular deep net architectures, whereas prior ideas from adaptive data analysis gave no nontrivial estimates. We call our estimate Rip van Winkle’s Razor which combines references to Occam’s Razor and the mythical person who fell asleep for 20 years...
  • Deep learning model compression
    This post covers model inference optimization or compression in breadth and hopefully depth as of March 2021. This includes engineering topics like model quantization and binarization, more research-oriented topics like knowledge distillation, as well as well-known-hacks...

Data Science Articles & Videos

  • Progressively approaching Kaggle
    After mentoring ~ 100 folks in Machine Learning during the last ~ 3yrs, this is my experience of what seems to be working best to get more people onto Kaggle...Kaggle's Tabular Playground Series (TSP) is a great place to start with a progressive plan. Be patient, work hard & keep practising....
  • Mapping Mangrove Growth and Deforestation with Satellite Imagery
    I’ve trained a convolutional neural network on year 2000 satellite image data in order to classify pixels as mangroves or not-mangroves. I’ve applied this model to 2020 data in order to track changes in mangroves over the last 20 years for the Florida coastline...The approach detailed here can be a powerful tool to automate remote monitoring of these extraordinary and special habitats...
  • Relighting And Color Grading With Machine Learning
    Continuity can be a challenge for [Photo/Video] shoots that are plagued by varying weather conditions, where, for instance, the pick-up shots are in bright sunlight but the core footage was shot under an even layer of cloud... Neural networks have been brought to bear on the problem for a few years now. In 2019 a Google-led academic collaboration presented a novel neural network that implemented a rudimentary process for relighting, though the results were not entirely convincing[2]...In 2020 another collaboration, this time between Amazon, Adobe and the University of Maryland, developed a relighting algorithm capable of working on portraits as large as 1024x1024 – which is pretty HD for the image synthesis space, at least at the moment...
  • Investigation: Robotic Process Automation (RPA)
    RPA bots take control of your computer (mouse and keyboard) and do the boring repetitive tasks that we humans are too often stuck with. They do so through a series of conditions, loops, and commands, coded to control the graphic user interface...In the below Jupyter Notebook, I discuss one of the more popular packages — PyAutoGUI. I walk through setting up PyAutoGUI, popular functions, and a demo. The demo shows a use case where a user needs to download multiple monthly building permit text files from the Census Bureau...
  • What is Similarity Search?
    What does Euclid of Alexandria have to do with Nike shoes? Find out in this intro to similarity search...
  • How to Create Mathematical Animations like 3Blue1Brown Using Python
    Wouldn’t it be cool if you can learn how he created these animations so you can create similar animations to explain some data science concepts to your teammates, managers, or followers?...Luckily, Grant puts together a Python package called manim that enables you to create mathematical animation or pictures using Python. In this article, you will learn how to create mathematical animations like below using manim...
  • Branch Specialization
    This article describes branch specialization, one of three larger “structural phenomena” we’ve been able observe in neural networks. (The other two, equivariance and weight banding, have separate dedicated articles.) Branch specialization occurs when neural network layers are split up into branches. The neurons and circuits tend to self-organize, clumping related functions into each branch and forming larger functional units – a kind of “neural network brain region.” We find evidence that these structures implicitly exist in neural networks without branches, and that branches are simply reifying structures that otherwise exist...
  • A Bot that Bird Watches so You Don’t Have To
    If you have ever tried to watch a live nest camera hoping to observe a falcon or other interesting bird, you may have had the experience of opening the live stream and seeing an empty nest. Not sure how long you should wait for the bird to return? In this article, I will describe my project aimed at automating nest monitoring for the Nottingham Trent University Falcon Cam. Using deep learning and automation tools, I designed a method for 24-hour bird detection that serves as an infrastructure upon which a Twitter bot or other notification system can be built to notify users when the bird enters or leaves the nest...

What is Data Observability?

Investing in data observability is becoming increasingly important as companies collect more and more (often third-party) data. Introducing new data sources and expanding access to new data consumers also leads to more complex pipelines—which increases the opportunities for missing, stale, or duplicate data to affect your business. Barr Moses, CEO and co-founder of Monte Carlo, explains how data engineers can leverage best practices from DevOps and engineering to fix data quality at scale.
