A robotic system is kinematically redundant when it possesses more degrees of freedom than those required to execute a given task. This paper reviews the well-known methods used to find the inverse kinematics of redundant manipulators. Because redundant manipulators have infinite solutions for their inverse kinematics, therefore the conventional method that was used to calculate the inverse kin...

Spectral algorithms for learning low-dimensional data manifolds have largely been supplanted by deep learning methods in recent years. One reason is that classic spectral manifold learning methods often learn collapsed embeddings that do not fill the embedding space. We show that this is a natural consequence of data where different latent dimensions have dramatically different scaling in obser...

A task based approach to the issue of redundant robots starts from the premise that there are obstacles that cannot be removed from the working area and which therefore must be avoided . This statement produces the requirement for a device with a certain degree of mobility , and stresses the need to ensure that the aim is twofold : reach the goal and avoid obstacles . But avoiding obstacles is ...

Clinicians frequently see the “right middle lobe” referred to in radiology reports, textbooks, and medical journals. Yet, there is no “left” middle lobe to distinguish it from, save a rare patient with Kartagener syndrome. We do not refer to the lingula as the “left” lingula. “Right” adds nothing to our understanding of the anatomic position of the lobe. So “right” is redundant when talking abo...

In the context of previous work on redundant modeling, permutation problems and matrix modeling, we introduce the notion of partial redundant modeling and categorical channeling constraints. To do so, we look at problems with categorical structure. Categorical channeling constraints also introduce the more general notion of channeling constraints over global constraints in redundant models. Thi...

In this paper we propose and experimentally evaluate a data integration approach where the uncertainty generated during the comparison and merging of the input data sources is included into the resulting mediated schema, and can be used to provide richer answers to the users. We describe a system implementing our method, and use it to empirically study the impact of uncertainty management on th...
