When speaking about linear programming problems of big dimensions with rare matrix of the system, solved through simplex method, it is necessary, at each iteration, to calculate the inverse of the base matrix, which leads to the loss of the rarity character of the matrix. The paper proposes the replacement of the calculus of the inverse of the base matrix with solving through iterative parallel...

In this paper, we propose a method for text-query-based keyword spotting from online Chinese handwritten documents using character classi ̄cation model. The similarity between the query word and handwriting is obtained by combining the character classi ̄cation scores. The classi ̄er is trained by one-versus-all strategy so that it gives high similarity to the target class and low scores to the oth...

Abstract: This note illustrates, using simple examples, how causal questions of non-trivial character can be represented, analyzed and solved using linear analysis and path diagrams. By producing closed form solutions, linear analysis allows for swift assessment of how various features of the model impact the questions under investigation. We discuss conditions for identifying total and direct ...

The Wigner distribution (WD) is perhaps the most prominent quadratic time–frequency signal representation. In this paper, which has mainly tutorial character but also contains some new results, we describe extensions of the WD concept to multidimensional vector signals, nonstationary random processes, linear time-varying systems (deterministic and random), linear signal spaces, and frames. We d...

This article presents a model of character recognition and the experiments used to develop and test it. The model applies to foveal viewing of blurred or unblurred characters and to tactile sensing of raised characters using the fingerpad. The primary goal of the model is to account for variations in legibility across character sets; a secondary goal is to account for variations in the cell ent...

abounovas is of unique character who has  always stimulates old and new critics to battle against each other as far as each person makes a character for him based on their understanding and special orientation instead of discovering his true  character. to recognize his real character ,however, his biography must be reread and to have a correct and real conclusion we have to refer to  reliable ...

We develop a new method to solve the irreducible character problem for a wide class of modules over the general linear superalgebra, including all the finite-dimensional modules, by directly relating the problem to the classical KazhdanLusztig theory. We further verify a parabolic version of a conjecture of Brundan on the irreducible characters in the BGG category O of the general linear supera...

In data visualization, characterizing local geometric properties of non-linear projection manifolds provides the user with valuable additional information that can in uence further steps in the data analysis. We take advantage of the smooth character of GTM projection manifold and analytically calculate its local directional curvatures. Curvature plots are useful for detecting regions where geo...
