Class RandomInsertion<T>

Namespace

Remarks

For Beginners: Random insertion adds new words to the text based on synonyms of existing words. For example, "I love programming" might become "I love really programming" if "really" is considered related to context.

When to use:

• Text classification tasks
• Training data expansion
• Making models robust to longer text variations

Constructors

RandomInsertion(int, double, string)

Creates a new random insertion augmentation.

public RandomInsertion(int numInsertions = 1, double probability = 0.2, string languageCode = "en")

Parameters

numInsertions int

Number of words to insert (default: 1).

probability double

Probability of applying this augmentation (default: 0.2).

languageCode string

Language code for language-specific operations.

Properties

CustomInsertionWords

Gets or sets custom words for insertion.

public Dictionary<string, string[]>? CustomInsertionWords { get; set; }

Property Value

Dictionary<string, string[]>

NumInsertions

Gets the number of insertions to perform.

public int NumInsertions { get; }

Property Value

int

Remarks

Default: 1

Methods

ApplyAugmentation(string[], AugmentationContext<T>)

context AugmentationContext<T>

The augmentation context.

Returns

string[]

The augmented data.

GetParameters()

Gets the parameters of this augmentation.

public override IDictionary<string, object> GetParameters()

Returns

IDictionary<string, object>

A dictionary of parameter names to values.
