Gabriel Budel
I'm an Applied Scientist at Uber with a Ph.D. in Artificial Intelligence and Network Science from TU Delft. My Ph.D. research focused on embeddings of complex networks and the roles of complementarity and similarity in these embeddings, with applications to semantic networks and NLP. My interests include artificial intelligence, machine learning, causal inference, hyperbolic graph embeddings, deep learning, and NLP.
