A cost-sensitive constrained Lasso

Algorithms for Fitting the Constrained Lasso

We compare alternative computing strategies for solving the constrained lasso problem. As its name suggests, the constrained lasso extends the widely-used lasso to handle linear constraints, which allow the user to incorporate prior information into the model. In addition to quadratic programming, we employ the alternating direction method of multipliers (ADMM) and also derive an efficient solu...

A pH-sensitive peptide-containing lasso molecular switch.

The synthesis of a peptide-containing lasso molecular switch by a self-entanglement strategy is described. The interlocked rotaxane molecular machine consists of a benzometaphenylene[25]crown-8 (BMP25C8) macrocycle surrounding a molecular axle. This molecular axle contains a tripeptidic sequence and two molecular stations: a N-benzyltriazolium and a pH-sensitive anilinium station. The tripeptid...

A multi-objective resource-constrained optimization of time-cost trade-off problems in scheduling project

This paper presents a multi-objective resource-constrained project scheduling problem with positive and negative cash flows. The net present value (NPV) maximization and making span minimization are this study objectives. And since this problem is considered as complex optimization in NP-Hard context, we present a mathematical model for the given problem and solve three evolutionary algorithms;...

A Multiple Model Cost - Sensitive

A cost effective and sensitive method for the determination of ammonia concentration in nanocrystal mordenite

The reduction capacity of ammonia while present even at ppm level can be demonstrated by the increased encounter probability between ammonia and methylene blue dye (MB+) incorporated in nanomordenite and Na-MOR zeolites. The rate of reduction methylene blue dye by ammonia on the surface nanomordenite zeolite is faster than Na-mordenite (Na-MOR) zeolite.Because nanomordenite zeolite with high si...
