Class MatchingNetworksModel<T, TInput, TOutput>

Namespace

AiDotNet.MetaLearning.Algorithms

Assembly

AiDotNet.dll

Matching Networks model for inference.

public class MatchingNetworksModel<T, TInput, TOutput> : IModel<TInput, TOutput, ModelMetadata<T>>

Type Parameters

T

The numeric type.

TInput

The input data type.

TOutput

The output data type.

Remarks

This model encapsulates the Matching Networks inference mechanism with pre-computed support embeddings. It is returned by Adapt(IMetaLearningTask<T, TInput, TOutput>) and provides fast classification using attention over support examples.

Constructors

MatchingNetworksModel(IFullModel<T, TInput, TOutput>, TInput, TOutput, MatchingNetworksOptions<T, TInput, TOutput>, INumericOperations<T>)

Initializes a new instance of the MatchingNetworksModel.

public MatchingNetworksModel(IFullModel<T, TInput, TOutput> encoder, TInput supportInputs, TOutput supportLabels, MatchingNetworksOptions<T, TInput, TOutput> options, INumericOperations<T> numOps)

Parameters
