distance_gauge

class cockpit.instruments.distance_gauge(self, fig, gridspec)

Distance gauge showing two different quantities related to distance.

This instruments shows two quantities at once. Firstly, the \(L_2\)-distance of the current parameters to their initialization. This describes the total distance that the optimization trajectory “has traveled so far” and can be seen via the blue-to-green dots (and the left y-axis).

Secondly, the update sizes of individual steps are shown via the yellow-to-blue dots (and the right y-axis). It measure the distance that a single parameter update covers.

Both quantities are overlayed with an exponentially weighted average.

Requires

The distance instrument requires data from both, the UpdateSize and the Distance quantity class.

Parameters

• self (CockpitPlotter) – The cockpit plotter requesting this instrument.

• fig (matplotlib.figure.Figure) – Figure of the Cockpit.

• gridspec (matplotlib.gridspec.GridSpec) – GridSpec where the instrument should be placed
