1. Recurrent Neural Networks (RNNs) are a vital class of neural networks designed to handle sequential data by integrating past information into current processing. Unlike feedforward networks, RNNs possess an intrinsic "memory" that makes them ideal for tasks where context and order matter, such as language understanding, stock prediction, and music composition. By transforming sequential data into meaningful outputs, RNNs excel at interpreting temporal dependencies, making them indispensable in deep learning applications involving sequences.

2. The RNN cell processes sequential data element by element, combining the current input with the previous hidden state. This hidden state acts as the network's internal memory, capturing information from past inputs. The hidden state is a vector encoding the network’s understanding of the sequence up to a point. It updates dynamically with each input, enabling the RNN to maintain context and learn dependencies over time. The RNN Architecture and Memory RNN Cell Function Hidden State Role

3. Basic RNNs struggled to learn long-range dependencies due to gradients diminishing during training. LSTMs use gates—input, output, and forget—to regulate information flow, selectively retaining or discarding data to capture long-term dependencies effectively. This architecture enables LSTMs to excel in language modeling, time series prediction, and other tasks requiring memory over extended sequences.

4. RNNs power language modeling, text generation, machine translation, sentiment analysis, and question answering. They convert speech to text and assist in image captioning and video action recognition by analyzing sequences of frames. RNNs predict future values in stock prices and weather by modeling temporal dependencies in sequential data.
