Creating Dota 2 hero embeddings with Word2vec

One of the coolest results in natural language processing is the success of word embedding models like Word2vec. These models are able to extract rich semantic information from words using surprisingly simple models like CBOW or skip-gram. What if we could use these generic modelling strategies to learn embeddings for something completely different - say, Dota 2 heroes.

In this post, we'll use the OpenDota API to collect data from professional Dota 2 matches and use Keras to train a Word2vec-like model for hero embeddings.

Estimating enzyme kinetics parameters from steady-state observations

In yesterday's post, we did some simple fitting of a Michaelis-Menten enzyme kinetics model for a single step of an isolated reaction. What happens when we have multiple reactions with multiple species involved occuring at the same time? Is it possible to infer something about the kinetic parameters of such a system by only looking at the steady-state concentrations of the species in the system under different experimental conditions? In this post, we'll apply some differential equations and simple optimization in Python to try to find out.
