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)

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!
