The Class Imbalance Problem: AdaBoost to the Rescue?

[available 26 August 2021 at 17:00 BST]

Here we discuss the issues when applying Random Forests and AdaBoost data analysis methods to infrared spectroscopy data sets, where the numbers in each class vary.

Introduction to ChiToolbox

This video is from an impromptu presentation at the Chemometrics in Vibrational Spectroscopy webinar programme organised by the Raman Imaging Group in the Faculty of Chemistry, Jagiellonian University in Kraków, 14 July 2020. [runtime 58:32]

The presentation was unplanned, hence the somewhat haphazard performance!
