LinearSVC - sklearn

Nettet18. sep. 2024 · I'm fine tuning parameters for a linear support vector machine. There are multiple ways to do it, but I wanted to compare LinearSVC and SDGClassifier in terms of time. I expected the accuracy score to be the same but, even after fine tuning with GridSearchCV, the score of the LinearSVC is lower. NettetLinearSVC Linear Support Vector Classification. Similar to SVC with parameter kernel=’linear’, but implemented in terms of liblinear rather than libsvm, so it has more flexibility in the choice of penalties and loss functions and should scale better to large numbers of samples. geoff neal vs shavkat rakhmonov prediction https://amgassociates.net
