Decision Theoretic Cutoff and ROC Analysis for Bayesian Optimal Group Testing
Ayaka Sakata, Yoshiyuki Kabashima
We study the inference problem in the group testing to identify defective items from the perspective of the decision theory. We introduce Bayesian inference and consider the Bayesi…
Evaluation of Generalized Degrees of Freedom for Sparse Estimation by Replica Method
Ayaka Sakata
We develop a method to evaluate the generalized degrees of freedom (GDF), which is a key quantity of a model selection criterion, for linear regression with sparse regularization.…
Replica Symmetric Bound for Restricted Isometry Constant
Ayaka Sakata, Yoshiyuki Kabashima
We develop a method for evaluating restricted isometry constants (RICs). This evaluation is reduced to the identification of the zero-points of entropy, which is defined for submat…
Error correcting codes and spatial coupling
Rafah El-Khatib, Jean Barbier, Ayaka Sakata +1
These are notes from the lecture of Rüdiger Urbanke given at the autumn school "Statistical Physics, Optimization, Inference, and Message-Passing Algorithms", that took place in L…
