functional_mask_along_axis: Mask Along Axis (functional)

In torchaudio: R Interface to 'pytorch''s 'torchaudio'

Mask Along Axis (functional)

Description

Apply a mask along axis. Mask will be applied from indices [v_0, v_0 + v), where v is sampled from uniform (0, mask_param), and v_0 from uniform(0, max_v - v). All examples will have the same mask interval.

Usage

functional_mask_along_axis(specgram, mask_param, mask_value, axis)

Arguments

specgram	(Tensor): Real spectrogram (channel, freq, time)
mask_param	(int): Number of columns to be masked will be uniformly sampled from [0, mask_param]
mask_value	(float): Value to assign to the masked columns
axis	(int): Axis to apply masking on (2 -> frequency, 3 -> time)

Value

Tensor: Masked spectrogram of dimensions (channel, freq, time)
