Advanced Recurrent Neural Networks (RNNs) are sophisticated machine learning models designed to process sequential data by maintaining memory of previous inputs. They address limitations of basic RNNs, such as vanishing gradients, through architectures like Long Short-Term Memory (LSTM) and Gated Recurrent Units (GRU). These advanced models excel in tasks like language modeling, speech recognition, and time-series prediction by capturing long-range dependencies and complex patterns within sequences.
