traja.accessor.TrajaAccessor.augment_noise

TrajaAccessor.augment_noise(sigma: float = 0.1) → TrajaDataFrame

Add Gaussian noise to trajectory coordinates for data augmentation.

Parameters:

sigma (float) – Standard deviation of Gaussian noise relative to coordinate scale. Default 0.1 means 10% of the coordinate range.

Returns:

Noisy trajectory

Return type:

traja.TrajaDataFrame

Note

Useful for making deep learning models robust to measurement noise.
