### sigmoid层
将离散数据通过embedding查表得到的值，与连续数据的输入进行相乘再累加的操作，合为一个整体输入。我们又构造了一个初始化为0，shape为1的变量，将其与累加结果相加一起输入sigmoid中得到分类结果。
在这里，可以将这个过程理解为一个全连接层。通过embedding查表获得权重w，构造的变量b_linear即为偏置变量b，再经过激活函数为sigmoid。

### Loss及Auc计算
- 预测的结果通过直接通过激活函数sigmoid给出，为了得到每条样本分属于正负样本的概率，我们将预测结果和`1-predict`合并起来得到predict_2d，以便接下来计算auc。
