Parseval Proximal Neural Networks
Marzieh Hasannasab, Johannes Hertrich, Sebastian Neumayer +3
The aim of this paper is twofold. First, we show that a certain concatenation of a proximity operator with an affine operator is again a proximity operator on a suitable Hilbert sp…
Modular Riesz bases versus Riesz bases in Hilbert -Modules
Marzieh Hasannasab
In this paper, we give new characterizations of modular Riesz bases in Hilbert -modules. We prove that modular Riesz bases share many properties with Riesz bases in Hilbert sp…
Approximate frame representations via iterated operator systems
Ole Christensen, Marzieh Hasannasab
It is known that it is a very restrictive condition for a frame to have a representation as the orbit of a bounded operator und…
Alternatives to the EM Algorithm for ML-Estimation of Location, Scatter Matrix and Degree of Freedom of the Student- Distribution
Marzieh Hasannasab, Johannes Hertrich, Friederike Laus +1
In this paper, we consider maximum likelihood estimations of the degree of freedom parameter , the location parameter and the scatter matrix of the multivariate Student-…
