WebThe marked missing input values can be masked from all calculations in the network. We can do this by using a Masking layer as the first layer to the network. When defining the layer, we can specify which value in the input to mask. If all features for a timestep contain the masked value, then the whole timestep will be excluded from calculations.

Christian Relief Fund is a registered … WebMasks a sequence by using a mask value to skip timesteps. For each timestep in the input tensor (dimension #1 in the tensor), if all values in the input tensor at that timestep are equal to mask_value, then the timestep will be masked (skipped) in all downstream layers (as long as they support masking).. If any downstream layer does not support masking …
