Struct GruConfig

pub struct GruConfig {
    pub d_input: usize,
    pub d_hidden: usize,
    pub bias: bool,
    pub reset_after: bool,
    pub initializer: Initializer,
}

Configuration to create a gru module using the init function.

Fields

d_input: usize

The size of the input features.

d_hidden: usize

The size of the hidden state.

bias: bool

If a bias should be applied during the Gru transformation.

reset_after: bool

If reset gate should be applied after weight multiplication.

This configuration option controls how the reset gate is applied to the hidden state.

• true - (Default) Match the initial arXiv version of the paper Learning Phrase Representations using RNN Encoder-Decoder for Statistical Machine Translation (v1) and apply the reset gate after multiplication by the weights. This matches the behavior of PyTorch GRU.
• false - Match the most recent revision of Learning Phrase Representations using RNN Encoder-Decoder for Statistical Machine Translation (v3) and apply the reset gate before the weight multiplication.

The differing implementations can give slightly different numerical results and have different efficiencies. For more motivation for why the true can be more efficient see Optimizing RNNs with Differentiable Graphs.

To set this field to false use with_reset_after.

initializer: Initializer

Gru initializer
