Decomposes linear operators into pairs of smaller linear operators.

See Factorize or the Method Card for details.

Functions

 apply_factorization Replaces torch.nn.Linear and torch.nn.Conv2d modules with FactorizedLinear and FactorizedConv2d modules. factorize_conv2d Approximates a $$K \times K$$ convolution by factorizing it into a $$K \times K$$ convolution with fewer channels followed by a $$1 \times 1$$ convolution. factorize_matrix Approximates a matrix by factorizing it into a product of two smaller matrices. factorizing_could_speedup Whether factorizing a module a given amount could possibly yield a benefit.
