スパースモデリングによる計測データの解析

(京大院情報)
o田中利幸

Compressed sensing, a representative subject of sparse modeling, is a mathematical framework to solve an underdetermined linear equation on the basis of the assumption that the solution is sparse. It has wide applicability, since many physical measurement processes are formulated as a linear equation and there are many instances in real-world applications where quantities of interest are sparse in appropriately transformed domains. In this presentation we review sparse modeling and compressed sensing, as well as our recent study based on compressed sensing to visualize spatio-temporal distributions of chemical substances in vivo via magnetic resonance spectroscopic imaging.
