Data Science and Machine Learning (Theory and Projects) A to Z - RNN Architecture: ManyToMany Different Sizes Model

The video tutorial discusses the challenges of handling varying input and output sequence lengths in neural networks, particularly in the context of machine translation. It introduces the encoder-decoder architecture as a solution for modeling these problems, explaining how it processes inputs and generates outputs. The tutorial also covers the training of recurrent neural networks (RNNs), including techniques like gradient descent and advanced models such as LSTMs and GRUs, which address issues like the vanishing gradient problem.
