Joint Concept Matching based Learning for Zero-Shot Recognition
Wen Tang, Ashkan Panahi, Hamid Krim
Zero-shot learning (ZSL) which aims to recognize unseen object classes by only training on seen object classes, has increasingly been of great interest in Machine Learning, and has…
A Novel Sparsity-Based Approach to Recursive Estimation of Dynamic Parameter Sets
Ashkan Panahi, Mats Viberg
We consider the problem of estimating a variable number of parameters with a dynamic nature. A familiar example is finding the position of moving targets using sensor array observa…
Asymptotically Exact Error Analysis for the Generalized -LASSO
Christos Thrampoulidis, Ashkan Panahi, Babak Hassibi
Given an unknown signal and linear noisy measurements , the generalized -LASSO…
Precise Error Analysis of the -LASSO
Christos Thrampoulidis, Ashkan Panahi, Daniel Guo +1
A classical problem that arises in numerous signal processing applications asks for the reconstruction of an unknown, -sparse signal from underdetermined, noisy, li…
A robust l_1 penalized DOA estimator
Ashkan Panahi, Mats Viberg
The SPS-LASSO has recently been introduced as a solution to the problem of regularization parameter selection in the complex-valued LASSO problem. Still, the dependence on the grid…
