"Variational Inference and Probabilistic Embeddings"

Representation learning based on neural embeddings has experienced asurge in popularity. In this talk, I analyze word embeddings, knowledgegraph embeddings, and image embeddings through the lens of probabilisticmodeling. I will first summarize my group’s activities in creating andexploring probabilistic formulations and extensions of these models,such as dynamic word embeddings for language evolution, augmentedknowledge graph embeddings for link prediction, as well as sequentialvariational autoencoders for video prediction and compression. In thesecond part, I will talk about improving variational inference as apopular training paradigm for neural probabilistic modeling, where Ifocus on perturbative variational bounds, iterative amortized inference,and Quasi-Monte Carlo variational inference.
