In recent years, there has been growing interest in learning to rank. The introduction of feature selection into different learning problems has been proven effective. These facts motivate us to investigate the problem of feature selection for learning to rank. We propose a joint convex optimization formulation which minimizes ranking errors while simultaneously conducting feature selection. This...
This paper focuses on a family of 3-PRPaR spatial translational parallel robots whose the moving platform is linked to the base by three PRPaR topological limbs, and the P joint fixed in the base acted as a actuated one in each limb. A systemic approach is employed to find all possible parallel robots of this family. Firstly, two types of the PRPaR limbs and their normal subgroups are defined base...
This paper focuses on the construction approach of a family of spatial translational parallel robots (STPRs) whose actuated joint of each limb is a prismatic joint and is fixed in the base. This family of robots has potentially wide range of application in the field of industry due to their high stiffness and acceleration. A lot of topological limbs were proposed in the literatures. But, how construct...
