Web12 de jun. de 2024 · I wanted to perform 10-fold cross validation and get the f-measure of the classification. I initially tried the following code. scores = cross_validate (clf, X, y, cv=k_fold, scoring = ('f1_weighted')) However, I got the error ValueError: multiclass-multioutput is not supported. WebMulticlass classification models classify each observation in a dataset into one of many categories. Evaluating these multiclass classification models for their performance, once they are trained, is crucial. The AI & Analytics Engine suggests the most suitable metric for this purpose as Prediction Quality.
