Handling Long Sequences
Description:
Explore recurrent neural networks for sentence and language modeling in this comprehensive lecture from CMU's Neural Networks for NLP course. Dive into the structure and capabilities of RNNs, understand the vanishing gradient problem and how LSTMs address it, and examine the strengths and weaknesses of recurrence in sentence modeling. Learn about pre-training techniques for RNNs and gain insights into handling long sequences and long-distance dependencies in language processing. Discover practical applications like language modeling and sentence representation through detailed examples and explanations.
