WebThe GRU was introduced by Cho et al. [ 64 ]. Although it was inspired by the LSTM unit, it is considered simpler to calculate and implement. It retains the LSTM immunity to the vanishing gradient problem. Its internal structure is simpler and, therefore, it is also easier to train, as less calculation is required to upgrade the internal states.
