Websample_weights is used to provide a weight for each training sample. That means that you should pass a 1D array with the same number of elements as your training samples (indicating the weight for each of those samples). class_weights is used to provide a weight or bias for each output class. Websample_weight array-like of shape (n_samples,), default=None. Sample weights. zero_division “warn”, 0 or 1, default=”warn” Sets the value to return when there is a zero division: recall: when there are no positive labels. precision: when there are no positive predictions. f-score: both. If set to “warn”, this acts as 0, but warnings ... WebApr 13, 2024 · Table 7 also shows the performance statistics for the PLS model. Statistically, the model with five components has a quite high R 2 of 92% and R 2 (pred) of 89% , which are good indicators of its fitting ability and predictive accuracy. bosch grass trimmer battery
