teras.layers.MixUp

class teras.layers.MixUp(alpha=1.0, lambda_seed=1337, shuffle_seed=1999, **kwargs)

MixUp is a regularization layer proposed by Hongyi Zhang et al. in the paper, mixup: BEYOND EMPIRICAL RISK MINIMIZATION

It was originally proposed for image data but here it has been adapted for Tabular data.

Parameters:

• alpha (float) – float, Parameter for the Beta distribution to sample lambda_ from which is used to interpolate samples.

• lambda_seed (int) – int, seed for sampling lambda_ value from beta distribution. Defaults to 1337

• shuffle_seed (int) – int, seed for randomly shuffling inputs. Defaults to 1999
