高斯-伯努利RBM

[cjlhxls]

您好，请问一下在guass-bin的重建过程中，act_function为什么用affine而不是guass?
即 def reconstruction(self,h):
logits = tf.matmul(h, tf.transpose(self.W)) + self.bv
prob_v=self.v_func(logits)
return logits,prob_v

因为，公式推导出来就是这样的，p(v|h)服从高斯分布，取这个分布的均值，也就是 linear(h) 发送自 Windows 10 版邮件<https://go.microsoft.com/fwlink/?LinkId=550986>应用

不好意思还有个问题想要问您一下，DBN第一层为高斯-伯努利RBM的话，第二层还是高斯-伯努利RBM吗？或者是第二层应该是伯努利-伯努利型呢？ 谢谢！
