Class Weights 101: The One-Line Fix for Imbalanced Data That Beats SMOTE
dima806_dima · x · 2026-10-15
Dima Iakubovskyi published a Medium tutorial arguing that a single keyword argument — class weights — is the simplest fix for imbalanced datasets, avoiding the overhead of SMOTE-style resampling. The 7-minute read also warns that this parameter rewrites the model's predicted probabilities, so calibration matters.
