tic_gauge

class cockpit.instruments.tic_gauge(self, fig, gridspec)[source]

TIC gauge, showing the TIC versus iteration.

The TIC (either approximated via traces or using a diagonal approximation) describes the relation between the curvature and the gradient noise. Recent work suggested that at a local minimum, this quantitiy can estimate the generalization gap. This instrument shows the TIC versus iteration, overlayed with an exponentially weighted average.

Requires

The trace instrument requires data from the TICDiag or TICTrace quantity class.

Parameters
