Webb9 mars 2024 · In this post, I’ll show you how to visualize and compare your machine learning model performance with scikit-learn and Weights & Biases. We’ll also explore how each of these plots helps us understand our models better and pick the best one. We’ll cover plots that are useful for analyzing classification, regression and clustering models. WebbHere, we predict the class label y ^ via majority (plurality) voting of each classifier C j: y ^ = m o d e { C 1 ( x), C 2 ( x),..., C m ( x) } Assuming that we combine three classifiers that classify a training sample as follows: classifier 1 -> class 0 classifier 2 -> class 0 classifier 3 -> class 1 y ^ = m o d e { 0, 0, 1 } = 0
