Recovery of piecewise finite-dimensional continuous signals by exploiting sparsity

Abstract: Many inverse problems in science and engineering are formulated as recovery of piecewise finite-dimensional continuous (PFC) signals. Although the higher-order total variation (HTV) is known ...

ON ESTIMATION OF ISOTONIC PIECEWISE CONSTANT SIGNALS

Consider a sequence of real data points X₁, . . . , Xn with underlying means θ*₁, . . . ,θ*n. This paper starts from studying the setting that θ*i is both piecewise constant and monotone as a function ...

The Piecewise Concave Function

An important function which is neither concave nor convex often arises in production and inventory models. This function is herein called piecewise concave and can be considered to be a generalization ...
