WebApr 25, 2024 · Suspect #1 - Regularization. Neural networks are great at overfitting the training data, actually there is an experiment replacing CIFAR10 (image classification task) labels (y values) by random labels on the training dataset and the network fits the random labels resulting in almost zero loss. WebDetecting over fitting of SVM/SVC. I am using 3-fold cross validation and a grid search of the C and gamma parameters for a SVC using the RBF kernel I have achieved a classification score of 84%. When testing against live data the accuracy rate is 70% (1500 samples used). However, when testing against an un-seen hold out set the accuracy is 86% ...
