- Add dedicated PAD_token (index 2) for proper padding - Use pack_padded_sequence in encoder to handle variable-length sequences - Ensure encoder hidden state represents actual content, not padding - Add ignore_index=PAD_token to loss function to exclude padding from gradients - Update all embedding layers with padding_idx parameter - Add comprehensive documentation explaining padding handling best practices Fixes issues where: 1. GRU final hidden state could be from PAD tokens 2. Loss was computed on PAD tokens affecting training
