Sparsistency

English

Noun

1. Template:Lb Let $𝐛$ be a vector and define the support $\mathrm{supp}(𝐛)=\{i:{𝐛}_i\ne 0\}$ where ${𝐛}_i$ is the $i$th element of $𝐛$. Let $\widehat{𝐛}$ be an estimator for $𝐛$. Then sparsistency is the property that the support of the estimator converges to the true support as the number of samples grows to infinity.
