What is the purpose of the LSTM layer in Keras?

The LSTM (Long Short-Term Memory) layer in Keras is used to process sequential data, especially in natural language processing and time series analysis. The LSTM layer remembers previous information and uses it when needed to predict the next data point, making it ideal for handling data with long-term dependencies. It can capture the long-term dependencies in a sequence, avoid the vanishing gradient problem, and has a strong memory capacity. The LSTM layer plays a crucial role in training neural network models, improving the models’ ability to model sequential data.
