Last Saturday, in the UEFA Champions League final (think of it as Europe’s Super Bowl), Spanish giants Real Madrid defeated their Italian counterparts Juventus FC 4-1. It was a thrilling match, that saw both sides staking an equal claim to winning the match in the first half, with... Read more
Topic Modeling with LDA Introduction
Suppose you have the following set of sentences: I eat fish and vegetables. Fish are pets. My kitten eats fish. Latent Dirichlet allocation (LDA) is a technique that automatically discovers topics that these documents contain. Given the above sentences, LDA might classify the red words under the Topic...

Deciphering the Neural Language Model
Recently, I have been working on the Neural Networks for Machine Learning course offered by Coursera and taught by Geoffrey Hinton. Overall, it is a nice course and provides an introduction to some of the modern topics in deep learning. However, there are instances where the student... Read more
Why the most influential business AIs will look like spellcheckers (and a toy example of how to build one)
Forget voice-controlled assistants. At work, AIs will turn everybody into functional cyborgs through squishy red lines under everything you type. Let’s look at a toy example I just built (mostly to play with deep learning along the way). I chose as a data set Patrick Martinchek’s... Read more
A survey of cross-lingual embedding models
In past blog posts, we discussed different models, objective functions, and hyperparameter choices that allow us to learn accurate word embeddings. However, these models are generally restricted to capture representations of words in the language they were trained on. The availability of resources, training data, and... Read more
You Must Allow Me To Tell You How Ardently I Admire and Love Natural Language Processing
