Hi.
I have a question about one of basic principle of NEF, representation.
I can’t understand decoding process which minimize MSE between input signal and decoded signal.

Defining MSE is for finding optimal decoders. Is it right?

Is MSE defined between signals at each time t?
For example, input signal isx(t) = sin(t)
. Thenx(π/6) = 1/2
fort = π/6
, andx(π/2) = 1
fort = π/2
.
Sot = π/6
, decoding weight is changed by minimizing MSE at that time, and thent = π/2
, decoding weight is changed by minimizing MSE at that time?
