Expand description

Random Erasing augmentation.

Randomly erases rectangular regions in the input data with random values. This technique prevents overfitting and improves generalization, especially for image data.

Reference: Zhong et al., “Random Erasing Data Augmentation” (AAAI 2020)

§Parameters

p: Probability of applying erasing (default: 0.5)
scale: Range of proportion of erased area (default: [0.02, 0.33])
ratio: Range of aspect ratio of erased area (default: [0.3, 3.3])
value: Value to fill erased region (0.0 = zero, 1.0 = random, -1.0 = pixel mean)

Fields§

§probability: f64

Probability of applying erasing.

§scale_min: f64

Minimum proportion of erased area.

§scale_max: f64

Maximum proportion of erased area.

§ratio_min: f64

Minimum aspect ratio.

§ratio_max: f64

Maximum aspect ratio.

§fill_value: f64

Fill value (0.0 = zero, 1.0 = random).
