Struct TextAugmentParameters

pub struct TextAugmentParameters {
    pub p: f32,
    pub min_elements: Option<usize>,
    pub max_elements: Option<usize>,
}

Parameters for augmentation

Fields

p: f32

Probability of augmentation of single element Not true probability, but expected percent of elements to be augmented If not set fall back to default value of 0.3

min_elements: Option<usize>

Minimum elements for augmentation If not set - no limit

max_elements: Option<usize>

Maximum elements for augmentation If not set - no limit

Implementations

impl TextAugmentParameters

pub fn new( p: f32, min_elements: Option<usize>, max_elements: Option<usize>, ) -> Self

Create new AugmentParameters

Arguments

• p - Probability of augmentation of single element (expected percent of elements to be augmented)
• min_elements - Minimum elements for augmentation
• max_elements - Maximum elements for augmentation

pub fn num_elements(&self, input_size: usize) -> usize

Calculate number of elements to be augmented from input size

Arguments

• input_size - Size of input in elements (words, chars, etc.)

Examples

use fast_aug::text::TextAugmentParameters;

let params = TextAugmentParameters{p: 0.5, min_elements: None, max_elements: None};
// Apply only p
assert_eq!(params.num_elements(10), 5);

let params = TextAugmentParameters{p: 0.5, min_elements: Some(3), max_elements: Some(7)};
// Apply min_elements
assert_eq!(params.num_elements(4), 3);
// Apply min_elements, but reach input_size, so return input_size
assert_eq!(params.num_elements(1), 1);
// Apply max_elements
assert_eq!(params.num_elements(100), 7);
