RNN - as per the lectures, Si = sigmoid ( UXi + WSi-1 + b ) and Output = O( VSi + c)
hidden = i2h(input+hidden concatenation)
output = i2o(input+hidden concatenation) ( different sets of weights as compared to i2h)
How does one correlate these? is hidden same as Si? In that case why is output not V*hidden but a totally different set of weights applied to input+hidden concatenation?
