Racing through 2016 with so much on the front burner and yet it is timely to pause for a quick update on the launch of my new machine learning company, RaRe Technologies. The Start of Something Exciting I’ve heard from a few people who were confused when they received a recent newsletter from “RaRe Technologies”, when they signed up for …
One year ago, Tomáš Mikolov (together with his colleagues at Google) made some ripples by releasing word2vec, an unsupervised algorithm for learning the meaning behind words. In this blog post, I’ll evaluate some extensions that have appeared over the year.
The latest gensim release of 0.10.3 has a new class named Doc2Vec. All credit for this class, which is an implementation of Quoc Le & Tomáš Mikolov: “Distributed Representations of Sentences and Documents”, as well as for this tutorial, goes to the illustrious Tim Emerick. Doc2vec (aka paragraph2vec, aka sentence embeddings) modifies the word2vec algorithm to unsupervised learning of continuous …
Latent Dirichlet Allocation (LDA), one of the most used modules in gensim, has received a major performance revamp recently. Using all your machine cores at once now, chances are the new LdaMulticore class is limited by the speed you can feed it input data. Make sure your CPU fans are in working order!
There are tools and concepts in computing that are very powerful but potentially confusing to novices. One such concept is data streaming (aka lazy evaluation), which can be realized neatly and natively in Python. Do you know when and how to use generators, iterators and iterables?
