Why did the Neural Network cross the road?
Can a machine learning algorithm learn to tell a joke? I’ve experimented with neural networks and jokes before, teaching them to tell knock-knock jokes, or to generate April Fools pranks. In each case, the results were underwhelming. However, that could have been because the algorithm didn’t have much data to work with, just a couple of hundred examples of each type of joke. What happens when I give a neural network a LOT of examples to copy?...
Why the Future of Machine Learning is Tiny
I’m convinced that machine learning can run on tiny, low-power chips, and that this combination will solve a massive number of problems we have no solutions for right now. That’s what I’ll be talking about at CogX, and in this post I’ll explain more about why I’m so sure...

Improving Language Understanding with Unsupervised Learning
We’ve obtained state-of-the-art results on a suite of diverse language tasks with a scalable, task-agnostic system, which we’re also releasing. Our approach is a combination of two existing ideas: transformers and unsupervised pre-training. These results provide a convincing example that pairing supervised learning methods with unsupervised pre-training works very well...
Graph Convolutional Neural Networks for Web-Scale Recommender Systems
Here we describe a large-scale deep recommendation engine that we developed and deployed at Pinterest. We develop a data-efficient Graph Convolutional Network (GCN) algorithm PinSage, which combines efficient random walks and graph convolutions to generate embeddings of nodes (i.e., items) that incorporate both graph structure as well as node feature information. Compared to prior GCN approaches, we develop a novel method based on highly efficient random walks to structure the convolutions and design a novel training strategy that relies on harder-and-harder training examples to improve robustness and convergence of the model...
Physicist Max Tegmark on the promise and pitfalls of artificial intelligence
Tegmark recently spoke about AI’s potential — and its dangers — at IPsoft’s Digital Workforce Summit in New York City. After the keynote address, we spoke via phone about the challenges around AI, especially as they relate to autonomous weapons and defense systems like the Pentagon’s controversial Project Maven program. Here’s an edited transcript of the interview...
The Trouble with D3
Recently there were a couple of threads on Twitter discussing the difficulties associated with learning d3.js. I’ve also seen this come up in many similar conversations I’ve had at meetups, conferences, workshops, mailing list threads and slack chats. While I agree that many of the difficulties are real, the threads highlight a common misconception that needs to be cleared up if we want to help people getting into data visualization...
