Decorrelation through gain control
Decorrelation is typically thought to require lateral interactions. But how much can we gain just by gain control? The setting as usual is $N$-dimensional glomerular inputs $\xx$, driving projection neuron activity according to $\dot \yy \propto – \sigma^2 \yy + \xx – \WW \yy$, which at steady state gives an input output transformation $$(\II \sigma^2…
