LSTM Networks
Long Short-Term Memory (LSTM) networks are a specialized type of recurrent neural network (RNN) architecture designed to model sequential data by addressing the vanishing gradient problem in traditional RNNs. They use memory cells with gates (input, forget, and output) to control information flow, enabling them to learn long-term dependencies in time series, text, speech, and other sequential patterns. LSTMs are widely used in natural language processing, time series forecasting, and speech recognition tasks.
Developers should learn LSTM networks when working with sequential data where long-range dependencies are critical, such as in machine translation, sentiment analysis, or stock price prediction. They are particularly useful in natural language processing applications like text generation and named entity recognition, where context over many time steps must be preserved. Compared to simpler RNNs, LSTMs offer better performance on tasks requiring memory of past information over extended sequences.
