In this tutorial, we will introduce how to fix ValueError: Initializer for variable is from inside a control-flow construct, such as a loop or conditional when inheriting tensorflow RNNCell.
Zoneout is proposed in paper: Zoneout: Regularizing RNNs by Randomly Preserving Hidden Activations. It is also used in Tacotron 2. In this tutorial, we will introduce what it is and how to implement it using tensorflow.
Smoothing normalization is proposed in paper: Attention-Based Models for Speech Recognition. In this tutorial, we will introduce how to implement it in tensorflow.
