Hi, this week we have a tutorial on undersampling algorithms for imbalanced classification, a tutorial on combining oversampling and undersampling, and a tour of data sampling methods.

Discover how to delete examples from your dataset to improve performance:
>> Undersampling Algorithms for Imbalanced Classification

Discover specialized techniques that perform both oversampling and undersampling:
>> Combine Oversampling and Undersampling for Imbalanced Classification

Discover a suite of data sampling techniques available for imbalanced classification:
>> Tour of Data Sampling Methods for Imbalanced Classification

See his new book
Imbalanced Classification with Python
Better Metrics, Balance Skewed Classes, Cost-Sensitive Learning  ... "
