Here you can clearly understand how exactly GRU works Although the gated recurrent unit (or GRU) was developed after Long Short-Term Memory networks, it's actually a simpler model. Gated recurrent units use an update (u) gate and a reset (r) gate to decide what information is passed forward. The key idea behind GRUs is that the reset gate r controls how much of the previous hidden state influences.
