Long Short-Term Memory networks (LSTMs) are one of the most important architectures in deep learning for handling sequential data. Whether it’s language, time series, or speech, LSTMs solve a fundamental problem that simple RNNs struggle with: learning long-term dependencies.

This article serves as a theory-oriented guide to Long Short-Term Memory (LSTM) networks implemented in PyTorch, discussing their architecture and advantages over traditional Recurrent Neural Networks (RNNs). It examines the various components of LSTMs, evaluates their differences with other models like GRUs and Transformers, and illustrates their effectiveness through an example of Next-Word Prediction, ultimately showcasing the simplicity of utilizing LSTMs in real-world applications within the PyTorch framework.
