Radius neighbors classifier
WebClassifier implementing a vote among neighbors within a given radius. Parameters: radius – Range of parameter space to use by default for radius_neighbors () queries. weights – Weight function used in prediction. Possible values: ’uniform’: uniform weights. All points in each neighborhood are weighted equally. Websimbsig.neighbors.RadiusNeighborsClassifier.RadiusNeighborsClassifier.fit(self, X, y=None) . Fit classifier based on the radius neighbors from the training dataset. Parameters. Parameters. X – Training data passed in an array-like or h5py file format. Should be of shape (n_samples, n_features) or (n_samples, n_samples) if metric ...
