WebApr 28, 2024 · I understand how the batch normalization layer works, and with batch_size == 1 then my final batch norm layer, self.value_batchnorm will always output a zero tensor. This zero tensor is then fed into a final linear layer and then sigmoid layer. WebLayerNorm can be applied to Recurrent layers without any modifications. Since it normalizes over all dimensions except the batch dimension, LayerNorm is the method with the most number of points that share the same and that can be simply applied to recurrent layers. m7rl 072a awWebAug 21, 2024 · However, during evaluation the batchnorm layer tries to normalize both inputs with skewed running estimates, which yields the high loss values.
