  • Charting the ‘Data for Good’ Landscape
    The field of “data for good” is not only overshadowed by the public conversations about the risks rampant data misuse can pose to civil society, it is also a fractured and disconnected space...We are taking one tiny step forward in trying to make a more coherent Data for Good space with a landscape that makes clear what various Data for Good initiatives (and AI for Good initiatives) are trying to achieve, how they do it, and what makes them similar or different from one another...Below you will find a very preliminary landscape map, along with a description of the different kinds of groups in the Data for Good ecosystem and why you might need to engage with them...
  • Postmortem: A Year of Data Science Peer Review in Startups
    About a year ago I suggested two peer review processes for data science projects, outlined a structure for the process — including separate review of the research phase and the model design and implementation — and positioned it within the wider scope of a data science project flow (as it is practiced in startup companies). The framework also included a list of topics, pitfalls and questions that should be reviewed...Unsurprisingly, things did not go exactly as planned. Thus, this post is about what worked and what didn’t...
  • Amazon's Data Dragnet
    Amazon’s vast offerings—which include online as well as brick-and-mortar stores, an internet pharmacy, streaming services, smart speakers, security cameras, mobile apps, and a digital advertising network—have helped the company expand into nearly every aspect of people’s lives...the Tech Transparency Project (TTP) conducted a review of the company’s privacy policies, patent applications, and other open-source information to assess the full scope of its surveillance capabilities. The findings show that Amazon is collecting far more data about its users than many people realize...

Data Science Articles & Videos

 
  • Identifying Document Types at Scribd
    This post walks through how we built a computer vision model to identify and classify over 100 million user-uploaded documents at Scribd. We talk about challenges faced such as defining classes, gathering data and dealing with overconfident predictions in production. ...
  • Getting Started With Facebook AI Similarity Search (FAISS)
    Facebook AI Similarity Search (FAISS) is one of the most popular implementations of efficient similarity search, but what is it — and how can we use it?..What is it that makes Faiss special? How do we make the best use of this incredible tool?...Fortunately, it’s a brilliantly simple process to get started with. And in this article, we’ll explore some of the options FAISS provides, how they work, and — most importantly — how Faiss can make our search faster...
  • What are Diffusion Models?
    Diffusion models are a new type of generative models that are flexible enough to learn any arbitrarily complex data distribution while tractable to analytically evaluate the distribution. It has been shown recently that diffusion models can generate high-quality images and the performance is competitive to SOTA GAN...
  • A Systematic Survey of Text Worlds as Embodied Natural Language Environments
    Text Worlds are virtual environments for embodied agents that, unlike 2D or 3D environments, are rendered exclusively using textual descriptions...This systematic survey outlines recent developments in tooling, environments, and agent modeling for Text Worlds, while examining recent trends in knowledge graphs, common sense reasoning, transfer learning of Text World performance to higher-fidelity environments, as well as near-term development targets that, once achieved, make Text Worlds an attractive general research paradigm for natural language processing. ...
  • Overview of process automation engagement trends in the Fortune 1000
    In this post, we take a look at process automation engagement trends in Fortune 1000 companies. We will examine three main categories of process automation: Business Process Automation (BPA), Robotics Process Automation (RPA) and Intelligent Process Automation (IPA), and review how the most-engaged companies are implementing automation technologies...
  • AI-Generating Algorithms: A Unique Opportunity for the Evolutionary RL Community [Video]
    A clear trend in machine learning is that hand-designed pipelines are replaced by higher-performing learned pipelines once sufficient compute and data are available. I argue that trend will apply to machine learning itself...In this talk I explain why I think AI-GAs are not only the fastest path to general AI, but also that they offer a tremendous and unique opportunity to the evolutionary RL community (including researchers focused on Quality Diversity and Open-Endedness). I’ll describe examples of successfully combining ideas from evolution and mainstream RL, including our Go-Explore and POET algorithms. I’ll also highlight many future research directions our community is uniquely poised to pursue to capitalize on this historic opportunity...
  • Multi-Task Learning with Deep Neural Networks: A Survey
    Multi-task learning (MTL) is a subfield of machine learning in which multiple tasks are simultaneously learned by a shared model...In this survey, we give an overview of multi-task learning methods for deep neural networks, with the aim of summarizing both the well-established and most recent directions within the field...
  • Is MLP-Mixer a CNN in Disguise?
    Recently, a new kind of architecture - MLP-Mixer: An all-MLP Architecture for Vision (Tolstikhin et al, 2021) - was proposed which claims to have competitive performance with SOTA models on ImageNet without using convolutions or attention. But is this really true? Are the token-mixing or channel-mixing layers in the MLP Mixer architecture actually "Conv-free"? (Figure-1) The deep learning community is split on this idea...
  • The Quick and Dirty Guide to Building Your Data Platform
    For most organizations, building a data platform is no longer a nice-to-have but a need-to-have, with many companies distinguishing themselves from the competition based on their ability to glean actionable insights from their data...To make things a little easier, we’ve outlined the 6 must-have layers you need to include in your data platform and the order in which many of the best teams choose to implement them...
  • My Journey to Deep Learning - [Video] by Jeremy Howard
    For 20 years I used a wide variety of machine learning and optimization algorithms to tackle predictive modeling challenges in many fields. But today, I find that deep learning gives me the best results for most problems I tackle, including solving problems that previously were out of reach. Furthermore, I find that deep learning generally requires less manual tweaking, leading to fewer errors and quicker results. Here, I discuss what I've learned on this journey, and describe why I believe nearly all data scientists should invest heavily in becoming effective deep learning practitioners...
