MaPSS: Maths Postgraduate Seminar Series: Connor Smith -- Introduction to Feature Stability and Selection in Regression Models

Hello all, 

The next MaPSS talk of this semester will be at 17:00 on Mon 29th April in Carslaw 535.
It’s a great opportunity to meet fellow postgrads, listen to an interesting talk, and of
course get some free pizza!

Speaker: Connor Smith 

Title: Introduction to Feature Stability and Selection in Regression Models 

Abstract: This talk about regression modelling is designed to cover a few basic concepts
of both variable selection and stability.  We will first cover the idea of feature
selection and a few ways this is conducted; exhaustive searches, stepwise searches and
shrinkage methods.  Briefly covering resampling methodology, we will discuss the idea of
how small changes in the data can lead to the selection of different models otherwise
known as stability.  We will then quickly touch on a new way of identifying which
variables are important in a regression setting and how this is useful in more complex
situations.  By then end of the talk , you should understand a range of different
methods used to identify and select important variables in a regression setting.
