Newton’s method for reinforcement learning and model predictive control

open access: yesResults in Control and Optimization, 2022
The purpose of this paper is to propose and develop a new conceptual framework for approximate Dynamic Programming (DP) and Reinforcement Learning (RL). This framework centers around two algorithms, which are designed largely independently of each other ...

Programming Abstractions for Data Sharing in Distributed Spaces

open access: yes, 2017
The cost of moving data is becoming a dominant factor for performance and energy efficiency in high-performance computing systems. To minimize data movement, applications have to consider data placement in order to optimize data transfer between processing units.

Generic Programming in Space and Time: Abstractions for High Performance Code Generation

open access: yes, 2017
The development of high performance libraries on modern hardware is extremely difficult and often requires reimplementation or retuning with every new processor generation. Program generators that produce such libraries automatically from a high level description are an appealing solution but only few exist to date. The difficulty is in both the design

Spectral approach to linear programming bounds on codes

open access: yes, 2006
We give new proofs of asymptotic upper bounds of coding theory obtained within the frame of Delsarte's linear programming method. The proofs rely on the analysis of eigenvectors of some finite-dimensional operators related to orthogonal polynomials.
