Implementing QANet (Question Answering Network) with CNNs and self attentions

Apr 15, 2018 In this post, we will tackle one of the most challenging yet interesting problems in Natural Language Processing, aka Question Answering. We will implement Google’s QANet in Tensorflow. Just like its machine translation counterpart Transformer network, QANet doesn’t use RNNs at all which makes it faster to … Read moreImplementing QANet (Question Answering Network) with CNNs and self attentions

What I wish I’d done differently as a data science manager

On centralizing siloed data Apr 12, 2018 I still get nostalgic looking at the very first Pebbles. (Photo courtesy of Pebble’s first Kickstarter) In 2014, I joined Pebble, the smartwatch maker later acquired by Fitbit, to lead their data science & analytics team. I was interested in the challenges of managing … Read moreWhat I wish I’d done differently as a data science manager

Hierarchical Clustering on Categorical Data in R

Dissimilarity MatrixArguably, this is the backbone of your clustering. Dissimilarity matrix is a mathematical expression of how different, or distant, the points in a data set are from each other, so you can later group the closest ones together or separate the furthest ones — which is a core idea of clustering. … Read moreHierarchical Clustering on Categorical Data in R
