Brief Description of my Research Interests
I am currently a researcher in the area of Machine Learning. More specifically, I am pursuing a PhD on the subject of hierarchical analysis of multivariate time series through generative models. Some of the relevant topics in my thesis are the development of Bayesian models to explore and visualize dependent context data in a hierarchical setting, and the study of generalization through evidence and variational inference methods. In particular, I am interested in the unsupervised analysis of multivariate time series.
