Subspace learning in minimax detection

Raja Fazliza R. Suleiman, David Mary, Andre Ferrari
2014 2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)  
The considered minimax detection approach relies on a GLR test allied to a sparsity constraint. This approach conditions the optimization of the target subspaces, in number r L.  ...  While the exact solution of the minimax optimization problem can be found for r = 1, the problem for r > 1 is more intricate and we propose two algorithms aimed at finding an approximate solution.  ...  The performances of five learned dictionaries are evaluated: two of them generated by the K-SVD algorithm for r = 1 and r = 21 (d K-SVD and D K-SVD 21 ), another two by the greedy minimax approach for  ...
