Class InitializationStrategies<T>

Namespace

AiDotNet.Initialization

Assembly

AiDotNet.dll

Provides factory methods and default instances for initialization strategies.

public static class InitializationStrategies<T>

Type Parameters

T

The numeric type used for calculations.

Inheritance

object

InitializationStrategies<T>

Inherited Members

object.Equals(object)

object.Equals(object, object)

object.GetHashCode()

object.GetType()

object.MemberwiseClone()

object.ReferenceEquals(object, object)

object.ToString()

Remarks

This static class provides convenient access to commonly used initialization strategies as singletons, reducing memory allocations when the same strategy is used across multiple layers or networks.

Usage:

// Use lazy initialization for fast network construction
var strategy = InitializationStrategies<double>.Lazy;

// Use eager initialization for traditional behavior
var strategy = InitializationStrategies<double>.Eager;

// Use zero initialization for testing
var strategy = InitializationStrategies<double>.Zero;

// Load from file for transfer learning
var strategy = InitializationStrategies<double>.FromFile("weights.json");

Properties

Eager

Gets the default eager initialization strategy.

public static IInitializationStrategy<T> Eager { get; }

Property Value

IInitializationStrategy<T>

Remarks

Eager initialization initializes weights immediately during layer construction. This is the traditional approach that ensures all weights are ready before training.

Lazy

Gets the default lazy initialization strategy.

public static IInitializationStrategy<T> Lazy { get; }

Property Value

IInitializationStrategy<T>

Remarks

Lazy initialization defers weight initialization until the first forward pass, making network construction faster.

Zero

Gets the zero initialization strategy.

public static IInitializationStrategy<T> Zero { get; }

Property Value

IInitializationStrategy<T>

Remarks

Zero initialization sets all weights to zero. Use only for testing or specific architectures that require it. Not recommended for general training.

Methods

FromFile(string, WeightFileFormat)

Creates a new initialization strategy that loads weights from a file.

public static IInitializationStrategy<T> FromFile(string filePath, WeightFileFormat format = WeightFileFormat.Auto)

Parameters

filePath string

The path to the weights file.

format WeightFileFormat

The format of the weights file. Default is Auto-detect.

Returns

IInitializationStrategy<T>

An initialization strategy that loads weights from the specified file.

Remarks

Unlike the singleton strategies, this creates a new instance each time because it depends on the specific file path.
