Tied weights
Webb4 nov. 2024 · I’m trying to implement a deep Autoencoder in PyTorch where the encoder’s weights are tied to the decoder. Following the idea given here, [ Autoencoder with tied … Webb24 aug. 2024 · So we halve the number of weights in the model, which speeds training and reduces overfitting. An autoencoder with tied weights has decoder weights that are the transpose of the encoder weights, which is a form of parameter sharing. We reduce the number of parameters with parameter sharing.
