SafePILCO: a software tool for safe and data-efficient policy synthesis
Kyriakos Polymenakos, Nikitas Rontsis, Alessandro Abate +1
SafePILCO is a software tool for safe and data-efficient policy search with reinforcement learning. It extends the known PILCO algorithm, originally written in MATLAB, to support s…
Optimal Approximation of Doubly Stochastic Matrices
Nikitas Rontsis, Paul J. Goulart
We consider the least-squares approximation of a matrix C in the set of doubly stochastic matrices with the same sparsity pattern as C. Our approach is based on applying the well-k…
Accuracy of approximate projection to the semidefinite cone
Paul J. Goulart, Yuji Nakatsukasa, Nikitas Rontsis
When a projection of a symmetric or Hermitian matrix to the positive semidefinite cone is computed approximately (or to working precision on a computer), a natural question is to q…
