Random¶

class torchjd.aggregation.Random[source]¶

WeightedAggregator that computes a random combination of the rows of the provided matrices, as defined in Algorithm 2 of Reasonable Effectiveness of Random Weighting: A Litmus Test for Multi-Task Learning.

__call__(matrix, /)[source]¶

Computes the aggregation from the input matrix and applies all registered hooks.

class torchjd.aggregation.RandomWeighting[source]¶

Weighting [Matrix] that generates positive random weights at each call.

__call__(matrix, /)[source]¶

Computes the vector of weights from the input matrix and applies all registered hooks.

Parameters:: matrix (Tensor) – The matrix from which the weights must be extracted.
Return type:: Tensor
