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. ************************************************************************************** See you there!
