Learning Fast Algorithms for Linear Transforms Using Butterfly Factorizations

14 Mar 2019Tri DaoAlbert GuMatthew EichhornAtri RudraChristopher Ré

Fast linear transforms are ubiquitous in machine learning, including the discrete Fourier transform, discrete cosine transform, and other structured transformations such as convolutions. All of these transforms can be represented by dense matrix-vector multiplication, yet each has a specialized and highly efficient (subquadratic) algorithm... (read more)
