Deep Reinforcement Learning: Pong from Pixels
I'll discuss the core ideas, pros and cons of policy gradients, a standard approach to the rapidly growing and exciting area of deep reinforcement learning. As a running example we'll learn to play ATARI 2600 Pong from raw pixels.

What a Deep Neural Network thinks about your #selfie
We will look at Convolutional Neural Networks, with a fun example of training them to classify #selfies as good/bad based on a scraped dataset of 2 million selfies.

The Unreasonable Effectiveness of Recurrent Neural Networks
We'll train and sample from character-level RNN language models that learn to write poetry, latex math and code. We'll also analyze the models and get hints of future research directions.

Breaking Linear Classifiers on ImageNet
There have been a few recent papers that fool ConvNets by taking a correctly classified image and perturbing it in an imperceptible way to produce an image that is misclassified. In this post I show that ConvNets are an overkill: Simple linear classifiers are in fact susceptible to the same fooling strategy.

What I learned from competing against a ConvNet on ImageNet
The latest state of the art Image Classification networks have only 6.7% Hit@5 error on ILSVRC 2014 classification task. How do humans compare?

Feature Learning Escapades
Some reflections on the last two years of my research: The Quest for Unsupervised Feature Learning algorithms for visual data. Where it was, where it is, and where it's going. Maybe.

Switching Blog from Wordpress to Jekyll
I can't believe I lasted this long on Wordpress. I am switching permanently to Jekyll for hosting my blog, and so should you :) Details inside.

The state of Computer Vision and AI: we are really, really far away.
A depressing look at the state of Computer Vision Research and AI in general. For those who like to think that AI is anywhere close.

Lessons learned from manually classifying CIFAR-10
CIFAR-10 is a popular dataset small dataset for testing out Computer Vision Deep Learning learning methods. We're seeing a lot of improvements. But what is the human baseline?
