我猜应该是你的理解错了 |
仔细看代码吧,问题不大 |
concat之后再输出,在计算结果上,和论文中 sigmoid(y_FM+y_DNN) 单独计算再加和是一样的。 我觉得first order乘以feature_bias是多余的。因为embedding的结果与deep、second order拼接最后接一个projection layer,只看feat_value-projection这一块就已经是等价LR <w, x>的形式(论文中的公式2),在前面乘以一个feature_bias又不加非线性激活函数完全没必要。 PS:在gayhub上讨论,是不是还是用英语更合适? |
我也有此疑问, |
我们俩理解的一样,测一测哪一种策略指标高一点 |
老哥,我对你代码的理解,first_order是F维,second_order是K维,Deep层输出维度。这三个维度concat之后再加权输出?
这个跟论文好像不一样呀……
