Gated Recurrent Unit
A streamlined recurrent cell that uses gates to control memory with fewer parameters than an LSTM.
Definition
A gated recurrent unit is a recurrent network cell that uses gates to decide what information to keep or discard as it reads a sequence. It is a streamlined alternative to the LSTM (an earlier, more complex memory cell), combining the forget and input gates into a single update gate and merging the cell and hidden states. With fewer internal values to learn, GRUs often train faster while delivering comparable performance, and they remain useful in low-resource settings and hybrid models.
