Network-based whole-brain representational similarity learning

Video: https://vimeo.com/203310049 Speaker 1: Urvashi Oswal Title: Network-based whole-brain representational similarity learning Abstract: Technologies such as functional magnetic resonance imaging (fMRI) provide huge amounts of data that could help improve our understanding of the human brain but they are often plagued by many complications, including noise, high-dimensionality, strong and unknown …

Block CUR Decompostion: Matrix Approximation Using Groups of Columns and Inferring Relationships in High-dimensional Generalized Linear Autoregressive Processes

Video: https://vimeo.com/163595515 Urvashi Oswal – Block CUR Decomposition: Matrix Approximation using Groups of Columns A common problem in large-scale data analysis is approximating a matrix using a combination of specifically sampled rows and columns. Unfortunately, in many real-world environments, the ability to sample specific individual rows or columns of the …
