42 multioutput target data is not supported with label binarization

neural network with multiple outputs in sklearn - Stack Overflow After reading the question again, more carefully, I realized that you are trying to use a classifier function, i.e. you are trying to apply labels to your input data. This means that the function is expecting binary output. You are probably looking for a Multi-layer Perceptron regressor which will give continuous output values. sklearn.multioutput.MultiOutputClassifier — scikit-learn 1.1.1 ... Multi-output targets predicted across multiple predictors. Note: Separate models are generated for each predictor. predict_proba(X) [source] ¶ Return prediction probabilities for each class of each output. This method will raise a ValueError if any of the estimators do not have predict_proba. Parameters Xarray-like of shape (n_samples, n_features)

scikit-learn.org › stable › modulesAPI Reference — scikit-learn 1.1.1 documentation sklearn.multioutput: Multioutput regression and classification¶ This module implements multioutput regression and classification. The estimators provided in this module are meta-estimators: they require a base estimator to be provided in their constructor. The meta-estimator extends single output estimators to multioutput estimators.

Scikit-learn: Support for multi-class roc_auc scores I tried your code. But when I call this function, I meet a problem saying "Multioutput target data is not supported with label binarization". Then I remove the code "pred=lb.transform(pred)" in the function. However, I meet another problem that "Found input variables with inconsistent numbers of samples: [198, 4284]".

Multi target regression. This strategy consists of fitting one regressor per target. This is a simple strategy for extending regressors that do not natively support multi-target regression. New in version 0.18.

sklearn.preprocessing.LabelBinarizer - scikit-learn Represents the type of the target data as evaluated by utils.multiclass.type_of_target. Possible type are 'continuous', 'continuous-multioutput', 'binary', 'multiclass', 'multiclass-multioutput', 'multilabel-indicator', and 'unknown'. sparse_input_bool True if the input data to transform is given as a sparse matrix, False otherwise. See also Probabilistic labels vs. sample_weight · snorkel - Donuts Some classifiers in scikit-learn allow sample_weight to be specified. Would converting probabilistic labels to multiple records with corresponding sample weights work? Given that this is not the same as using probabilistic labels, what is expected in terms of improvement of the alternative approach suggested in the docs (rounded labels with probs_to_preds)? LabelEncoder + Inputer + LabelBinarizer in mapper fails - GitHub vruusmann commented on May 15, 2017 ValueError: Multioutput target data is not supported with label binarization This error belongs 100% to Scikit-Learn. It happens even if your workflow doesn't contain any PMML-related classes (eg. PMMLPipeline) in it. The solution is to add support for the sklearn_pandas.CategoricalImputer transformer class.

Value with which negative labels must be encoded. Value with which positive labels must be encoded. Set to true if output binary array is desired in CSR sparse format. Support for multi-class roc_auc scores #3298 - GitHub This would seem to be identical to using the current roc_auc_score with a binarized representation and average='weighted'. ( @arjoly, why do these curve-based scores disallow multiclass?) Otherwise, those slides, and most references I can find to "multi-class ROC", focus on multi-class calibration of OvR, not on an evaluation metric. gist.github.com › lebigot › 691ca1acf172b688996bd60cList of scikit-learn places with either a raise statement or ...

Can't answer without code really. Your error sounds like your code expects a one -dimensional target-array/y-array and you're trying to fit it with a multi-dimensional y_train. The y_train you mentioned has 2 columns. Check the inputs of your MLPClassifier.fit () method. It should not look like MLPClassifier.fit (X_train, y_train).
