The dynamic time warpĪlgorithm can do this, but it's just too slow! What do I do? Strings having some unknown number differences resulting from encodingĪrtifacts, escaped characters, and random errors.

You can import it into your deep learning projects. It's backed by unit tests,Īssumptions and workings of word2vec, and to gain more experience I recently implemented word2vec in python. Python implementation of Word2Vec Using Theano and Lasagne Useful for generating random words out of a large vocabulary based on a unigram distribution. But what about when the number of outcomes is very large? A naive approach will take time linear in the number of outcomes, but the alias method gives samples in constant time! My implementation gives on-demand samples from a categorical distribution with better performance than numpy. It’s not too hard to randomly generate samples from a discrete set of possible outcomes, given you have the probability for each outcome.

In topics relating to computer science, social informatics, machine learning, and data usage training in organizations for various types of users. I frequently give presentations, training courses, and teach in various formats Statistical and machine learning techniques, including recommender systems,Ĭlustering, visualization, data mining, and natural language analysis. I seed or grow organizations' data-literate culture. I connect users to data and help them learn to love to use My research is motivatedīy a desire to understand, and democratically enhance, collective behaviour.Īcademically, I pursue that through research in social media, machine learning, and natural language analysis.Ĭommercially, I build out data pipelines and reporting systems (business The dynamics of large populations-from social movements to naturalĭisasters-now unfolds in the digital commons.

Here you'll find weird things about me: my origami, my 'scholarly publications', and some pythony programmy type things.

I'm a Technologist, Humanist, and Student of Nature-or so I try to be!
