Gated Recurrent Unit (GRU) networks are a type of recurrent neural network designed to efficiently handle sequence data. GRUs are similar to LSTM networks but have a simpler structure, making them faster to train while still capturing important patterns in sequences.<\/p>\n\n\n\n

A GRU is an advanced RNN that uses gating mechanisms to control the flow of information. It combines memory and hidden state into a single representation, allowing it to retain relevant information and discard unnecessary data.<\/p>\n\n\n\n\n
