landscapelaser

Implementation of the landscapelaser PyPi package.

Calculates sharpness of the loss landscape of a model.

Use

To use the package, do:

from landscapelaser import LandscapeLaser
ll = LandscapeLaser()

import numpy as np
arr = np.random.random((20,20))

sharpness, mean_loss = ll.calculate(values=arr)
print(
    f'The sharpness measure of the loss landscape is `{sharpness}`'
    f' with mean loss over the landscape equal to `{mean_loss}`'
)

Here, arr is a 2d numpy array containing the loss values in the landscape. To calculate this, refer to loss-landscapes package.

Installation

The package is available on PyPI. Install using:

pip install landscapelaser
