The Generalization Spectrum: A Chromatographic Approach to Evaluating Learning Algorithms

Jinghan Zhang, Zerui Cheng, Shiqi Chen +5

Traditional evaluations measure a learning algorithm's final performance on an i.i.d. test set, reducing learning to a single aggregate score. This approach obscures a fundamental…
