Sample Weight

Sample Weight assigns weight to input sample. Weight may be specified by input param class_weight or sample_weight_name. Output data instances will each have a weight value, which will be used for training. While weighted instances may be used for prediction(SampleWeight component will assign weights to instances if prediction pipeline includes this component), Evaluation currently does not take weights into account when calculating metrics.

If result weighted instances include negative weight, a warning message will be given.

Please note that when weight is not None, only weight_diff convergence check method may be used for training GLM.

!!!Note

If both `class_weight` and `sample_weight_name` are provided, values
from column of `sample_weight_name` will be used.
