Recurrent Neural Networks

Recurrent Neural Networks (RNNs) are a class of artificial neural networks designed to process sequential data by maintaining an internal state or memory of previous inputs. They are particularly effective for tasks where the order and context of data points matter, such as time series analysis, natural language processing, and speech recognition. Unlike feedforward neural networks, RNNs have connections that form directed cycles, allowing information to persist across time steps.

Also known as: RNN, Recurrent Neural Network, Recurrent NN, Recurrent nets, Seq2Seq models (when used in sequence-to-sequence tasks)

Why learn Recurrent Neural Networks?

Developers should learn RNNs when working with sequential or time-dependent data, such as predicting stock prices, generating text, or translating languages, as they can capture temporal dependencies and patterns. They are essential for applications in natural language processing (e.g., sentiment analysis, machine translation) and audio processing (e.g., speech-to-text), where context from previous elements influences current outputs. However, for long sequences, alternatives like LSTMs or GRUs are often preferred due to RNNs' limitations with vanishing gradients.
