I would love to contribute to add the feature for class_weight in MLPClassifier. This is my first time contributing to an open-source project. I am working on getting familiar with the library, would love some guidance. What I think is that we need to add the functionality to all these...
sklearn的class_weight设置为'balanced'的计算方法 2019-12-05 21:44 −分类的时候,当不同类别的样本量差异很大时,很容易影响分类结果,因此要么每个类别的数据量大致相同,要么就要进行校正。 sklearn的做法可以是加权,加权就要涉及到class_weight和sample_weight,当不设置class_weight参数时,默认值是所有类别的权值...
但是,这不起作用,因为MLPClassifier没有实现AdaBoostClassifier所需的sample_weight (请参阅here)。在此之前,我尝试在AdaBoostClassifier中使用Keras模型和KerasClassifier,但也不能像前面提到的here那样工作。 用户V1nc3nt提出的way是在TensorFlow中构建自己的MLPclassifier,并考虑到sample_weight。 用户V1nc3nt分享了他...
