A question about P #12

Open eminemichael opened 5 years ago

eminemichael commented 5 years ago

When P=1, how is feature vector of this user trained, won't it be unchanged?

eelxpeng commented 5 years ago

I don't think so. Since V changes, U will change.

我想的是P=1，在取k-1份作为训练集后，验证集中所有用户的特征向量在损失函数就不出现了，只有训练集中的用户向量，这样怎么对验证集的用户向量更新呢
