This symbol represents the state of the forget gate of the LSTM.
This symbol represents the state of the forget gate of the Long Short-Term Memory block. It stands for a vector of real values.
The symbol, \(g^\text{forget}\), represents the state of the forget neuron to the Long Short-Term Memory block. It stands for a vector of real values. It is typically used with a related timestep, e.g. \(g^\text{forget}(n)\) represents the state of the output neuron at time \(n\).
