ML Engineer, Twitter
Mateusz is an ML Engineer at Twitter. He works on understanding what people are tweeting about: currently by the topic classification, earlier by the automated event detection. Before that he was analysing terabytes of scientific papers, looking for word boundaries in scriptio continua and leveraged data to guess how much milk a cow would produce. Big fan of logistic regression, kNN and pretty charts. Formerly at ICM University of Warsaw, Microsoft and True Knowledge (now Amazon).
