neg_mean_squared_error中的neg就是negative,即认为所有损失loss都是负数,计算结果为负的mse,因此需要在前面负号。 加负号之后跟下面调用make_scorer中的mean_squared_error计算结果一致。注意cross_val_score中的评价指标是没有 mean_squared_error的。 from sklearn.metrics import make_scorer scores = cross_val_...
loss_collection: 可选参数,用于指定损失应该添加到哪个集合中。在 TensorFlow 1.x 中较为常用,但在 TensorFlow 2.x 中通常不使用。 reduction: 指定应用于输出的减少操作,例如 tf.losses.Reduction.NONE、tf.losses.Reduction.SUM、tf.losses.Reduction.MEAN 等。默认值为 tf.losses.Reduction.SUM_BY_NONZERO_WEI...
