Select the correct answer pertaining to LSTM and GRU:

Select the correct answer pertaining to LSTM and GRU:

LSTM$\text{'}$s forget gate passes the previous hidden state through the tanh function

LSTM$\text{'}$s output gate decides what the previous hidden state should be

GRU is an older generation of neural networks

GRU's forget and input gates function as the update gate in LSTM

Hybrid models can combine both layers of LSTM and GRU
