Echo State Networks

Echo State Networks (ESNs) are a type of recurrent neural network designed for processing time-series data. They consist of a large, fixed pool of connected neurons, which create dynamic patterns when given input data. Unlike traditional neural networks, only the output layer is trained, while the rest remains unchanged, making training faster and simpler. This structure allows ESNs to capture complex temporal relationships in data, making them useful for tasks like speech recognition, forecasting, and signal processing. Their unique setup helps them efficiently learn and remember patterns over time without extensive computational demands.
