A full splitting algorithm for structured difference-of-convex programs
Radu Ioan Bot, Rossen Nenov, Min Tao
In this paper, we study a class of nonconvex and nonsmooth structured difference-of-convex (DC) programs, which contain in the convex part the sum of a nonsmooth linearly composed…
(Almost) Smooth Sailing: Towards Numerical Stability of Neural Networks Through Differentiable Regularization of the Condition Number
Rossen Nenov, Daniel Haider, Peter Balazs
Maintaining numerical stability in machine learning models is crucial for their reliability and performance. One approach to maintain stability of a network layer is to integrate t…
Accelerated Griffin-Lim algorithm: A fast and provably converging numerical method for phase retrieval
Rossen Nenov, Dang-Khoa Nguyen, Peter Balazs +1
The recovery of a signal from the magnitudes of its transformation, like the Fourier transform, is known as the phase retrieval problem and is of big relevance in various fields of…
Faster than Fast: Accelerating the Griffin-Lim Algorithm
Rossen Nenov, Dang-Khoa Nguyen, Peter Balazs
The phase retrieval problem is found in various areas of applications of engineering and applied physics. It is also a very active field of research in mathematics, signal processi…
