Lasso, Group Lasso, and SLOPE

SpeakerTulane University

Abstract:

 

From linear regression, I will introduce the penalty method such as ridge method and lasso method. However, in some cases, the variates have strong correlation with each other, then we can use the group lasso. After that, I will talk about SLOPE(sorted L-One Penalty Estimation), which is method similar to the lasso method and consider the false discovery rate as the criteria.

Everything You Always Wanted to Know About Pi (But Were Afraid to Ask)

Aram BinghamTulane University

Abstract:

Imagine all of the internet burns down, with all the books inside it, and we have to recreate the current state of mathematics with our bare brains. What facts about pi (pronounced pee) will we retain? After reciting some of the trivia which is Pi Day orthodoxy, we will discuss proofs of those aspects of pi we take most for granted, making reference to open problems as well.
