Estimation of the regression function by Legendre wavelets [PDF]

Iranian Journal of Numerical Analysis and Optimization, 2022
We estimate a function f with N independent observations by using Leg-endre wavelets operational matrices. The function f is approximated with the solution of a special minimization problem.

MOM: Matrix Operations in MLIR

CoRR, 2022
Modern research in code generators for dense linear algebra computations has shown the ability to produce optimized code with a performance which compares and often exceeds the one of state-of-the-art implementations by domain experts. However, the underlying infrastructure is often developed in isolation making the interconnection of logically ...

Adams operations on matrix factorizations [PDF]

Algebra & Number Theory, 2017
We define Adams operations on matrix factorizations, and we show these operations enjoy analogues of several key properties of the Adams operations on perfect complexes with support developed by Gillet-Soulé in their paper "Intersection Theory Using Adams Operations".
