Vicente Ivan Sanchez CarmonaI'm a fifth-year PhD student in computer science at University College London. I am part of the Machine Reading group. I'm working on understanding black-box models such as matrix factorization models and word embeddings. More concretely, I worked on a) extracting knowledge from a matrix factorization model, so one could understand why this complex model made a particular prediction. This knowledge is in the form of an interpretable model such as logic rules, decision trees and Bayesian networks., and b) understanding to what extent pre-trained word embeddings encode a hypernymy relation, i.e. given two word embeddings, can we know if the is-a relationship holds between them only by inspecting the vector representations? Well, it turns out that into some extent we can. My interests are Machine Learning, Natural Language Processing, Data Mining, and Cognitive Science. News |
