Conservation Laws and First-Order Optimization: Novel Insights and Algorithms

Abstract: Optimization is an indispensable tool in modern data analysis. A wide range of tasks, including training models for image classification, medical diagnosis, and prediction of natural disasters can be formulated as optimization problems. Given the scale and complexity of modern data sets and associated optimization problems, there is a real need for highly-efficient general-purpose optimization methods.

AI talk: Multiplex network optimization: capturing cognition and attention

I will examine how procedures for optimally searching through "multiplex" networks (networks made of multiple simple graphs) capture human learning and search patterns. Prior work on semantic memory (people's memory for facts and concepts) has primarily focused on modeling similarity judgments of pairs of words as distances between points in a high-dimensional space (e.g., LSA by Landauer et al, 1998; Word2Vec by Mikolov et al. 2013).

Precision Medicine Studies: Examination of Variants within the Gene: SLC5A2

As biobanks continue to grow and more and more human genomes are sequenced, our ability to detect relationships between genetic variants and diseases is at an unprecedented level. The exponential growth of biological data, including both genetic and health record data, has led to the development of association-based studies (GWAS and PheWAS) that paved the way for identifying links between genetic variations and the development of diseases.
