Autonomous Sparse Mean-CVaR Portfolio Optimization
The $\ell_0$-constrained mean-CVaR model poses a significant challenge due to its NP-hard nature, typically tackled through combinatorial methods characterized by high computational demands.
Dynamic PET cardiac and parametric image reconstruction: a fixed-point proximity gradient approach using patch-based DCT and tensor SVD regularization
For the cardiac/lung phantom, an additional cardiac gated 2D-OSEM set was reconstructed.
