> As defined by the lecturer herself, "h(t) = h(t-1)", the very definition of hysteresis.

How is that a definition of hysteresis?

Hysteresis is when state is a function of previous state, not identical to previous state.

It's just simplified pseudoscope using the lecturer's own notation from her slides to make my point.

The following is the lecturer's full TeX form if that helps:

h(t) = \tanh \left(h(t-1) W_{\text{hh}}^T+x(t) W_{\text{hx}}^T\right)

However, I don't want our readers to get distracted by line noise; h(t) = h(t - 1) makes my point.
