Statistical mechanics analysis of thresholding 1-bit compressed sensing
Yingying Xu, Yoshiyuki Kabashima
The one-bit compressed sensing framework aims to reconstruct a sparse signal by only using the sign information of its linear measurements. To compensate for the loss of scale info…
Sampling approach to sparse approximation problem: determining degrees of freedom by simulated annealing
Tomoyuki Obuchi, Yoshiyuki Kabashima
The approximation of a high-dimensional vector by a small combination of column vectors selected from a fixed matrix has been actively debated in several different disciplines. In…
Sparse approximation problem: how rapid simulated annealing succeeds and fails
Tomoyuki Obuchi, Yoshiyuki Kabashima
Information processing techniques based on sparseness have been actively studied in several disciplines. Among them, a mathematical framework to approximately express a given datas…
Cross validation in LASSO and its acceleration
Tomoyuki Obuchi, Yoshiyuki Kabashima
We investigate leave-one-out cross validation (CV) as a determinator of the weight of the penalty term in the least absolute shrinkage and selection operator (LASSO). First, on the…
