Learning of Data Collections in High-Dimensional Spaces without Supervision



Abstract

The democratization of information and communication technologies is making available huge quantities of data. Using this data in efficient ways will help to improve the activity of many sectors in different areas. In this regard, during the last few decades, methodologies, models, algorithms, and systems of machine learning were revisited; however, additional efforts are required to propose effective solutions to some open problems; among them -- scalability, dimensionality, feature selection, and updating.

During the past few years, my collaborators and I have proposed several machine learning algorithms to approach these problems in the case of both finite and infinite mixture models, as well as their use in real-world applications. This talk will focus on the learning of statistical models in the case of mixture of pdfs; specifically, the discriminative and generative learning, non-Gaussian data modeling, model selection, feature in the case of high dimensional space, and updating of mixture models. I will also illustrate the developed algorithms in the context of the recommendation of images.


PLEASE NOTE that this seminar will take place from 11:30 a.m. to 12:30 p.m.

The CVSL seminars are held on Fridays at 11:30 a.m. in room PLT-2783.
