ScaledDotProductAttention

class mmocr.models.common.ScaledDotProductAttention(temperature, attn_dropout=0.1)

Scaled Dot-Product Attention Module. This code is adopted from https://github.com/jadore801120/attention-is-all-you-need-pytorch.

参数

• temperature (float) – The scale factor for softmax input.

• attn_dropout (float) – Dropout layer on attn_output_weights.

forward(q, k, v, mask=None)

Defines the computation performed at every call.

Should be overridden by all subclasses.

注解

Although the recipe for forward pass needs to be defined within this function, one should call the Module instance afterwards instead of this since the former takes care of running the registered hooks while the latter silently ignores them.
