self.loss = tf.reduce_mean(-self.y * tf.log(self.yhat + 1e-24))
这边 y 的值好像是 1/0 ,这个loss是不是有问题
how to explain your rnn code, why use alpha? i think there dosnot need alpha operation, use lstm->cnn direct
你好,请问数据集在哪下载呢?
the youtube recommand you implement,isnot use word2vec,why?
楼主,您好,我的训练数据特征比较稀疏,有好多0,训练loss一直为nan,请问有什么解决办法么?
非常期待您的回答
楼主,您好,在我的数据集上,训练过程loss一直没有明显下降,有什么改进的办法么?
hi,dear 大佬
这是我的一些浅显的问题,
请指点下,多谢
1.能不能提供下数据集?
2.这里面的
data.columns = ['UId', 'ItemId', 'BrandId', 'MiddlesortId', 'ClickTime', 'Date']
middlesortId是啥?Date呢?
3.负采样是怎么做的啊?
self.sub_sample = tf.placeholder(tf.int32, [None, None]) # soft layer (pos_clict,neg_list)[B,sub_size]
4.y是什么呢?怎么是2维的呢?是one-hot之前的吧?link
self.y = tf.placeholder(tf.float32, [None, None]) # label one hot[B]
5.这里的item与brand及middlesort各自代表什么意思呢?我原以为item就是brand呢?
还是说item是物品,brand是牌子名字,middlesort又是什么呢?同问题2
item_emb_w = tf.get_variable("item_emb_w", [self.item_count, self.embedding_size])
brand_emb_w = tf.get_variable("brand_emb_w", [self.brand_count, self.embedding_size])
msort_emb_w = tf.get_variable("msort_emb_w", [self.msort_count, self.embedding_size])
6.请教下mask是表示什么?对这个词有点陌生
mask = tf.sequence_mask(self.sl, tf.shape(h_emb)[1], dtype=tf.float32) # [B,T]
另外这里的sl是什么啊?
还是请提供下数据及必要的说明吧
多谢大佬
