A dual active set algorithm for optimal sparse convex regression
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2019 The shape-constrained problems in statistics have attracted much attention in recent decades. One of them is the task of finding the best fitting monotone regression. The problem of constructing monotone regression (also called isotonic regression) is to

Observed and pooled-adjacent-violators algorithm response rate. [PDF]
, 2016 The estimator of the observed response rate (round dots, dotted line) and the PAVA-adjusted response rate (squares, solid line) at various lidocaine concentrations are plotted on the y-axis (A) for the C group and (B) for the D group.

Data-dependent contrast test for dose-finding clinical trials.
Contemporary Clinical Trials, 2023 We propose a simple and powerful data-dependent contrast test with ordinal-constraint contrast coefficients of the dose response determined from observed responses. The contrast coefficients are easily calculated using a pool-adjacent-violators algorithm

A new dual spectral projected gradient method for log-determinant semidefinite programming with hidden clustering structures [PDF]
Computational optimization and applicationsThis paper proposes a new efficient method for a sparse Gaussian graphical model with hidden clustering structures by extending a dual spectral projected gradient (DSPG) method proposed by Nakagaki et al. (Comput Opt Appl, 76(1):33–68, 2020).

How to project onto the monotone nonnegative cone using Pool Adjacent Violators type algorithms
, 2012 The metric projection onto an order nonnegative cone from the metric projection onto the corresponding order cone is derived. Particularly, we can use Pool Adjacent Violators-type algorithms developed for projecting onto the monotone cone for projecting onto the monotone nonnegative cone too.

An Algorithm for Predicting the Speed of Traffic Light Violators [PDF]
, 2011 The tracking of vehicles using RFID was developed consider three major problems, i.e. traffic signal timing, congestion on road and theft of vehicles. This paper describes an algorithm for predicting the speed of traffic light violators.

An Autoadaptive Edge-Detection Algorithm for Flame and Fire Image Processing [PDF]
, 2012 The determination of flame or fire edges is the process of identifying a boundary between the area where there is thermochemical reaction and those without. It is a precursor to image-based flame monitoring, early fire detection, fire evaluation, and the
