یکی از مهمترین پرسشهایی که در زمینه ریزساختار بازارهای مالی مطرح میشود، سنجش سطح نامتقارن بودن اطلاعات در بازارهای مالی است. طی سالهای اخیر معیار احتمال مبادله آگاهانه (PIN) برای اندازهگیری میزان نامتقارن بودن اطلاعات معرفی شده که مبتنیبر الگوهای اقتصادی و در چهارچوب ساختار خرد بازار است. رویکرد ایزلی و اوهارا (1992)، بهعنوان نخستین ایده مطرح شد. در ادبیات موجود دو مشکل در این روش تخمین ...
in this paper, we extend some propositions of banachalgebras into module actions and establish the relationships betweentopological centers of module actions. we introduce some newconcepts as -property and -property for banach modules and obtain some conclusions inthe topological center of module actions and arens regularity of banachalgebras.
The traditional subspace-based approaches to segmentation (often referred to as multi-body factorization approaches) provide spatial clustering/segmentation by grouping together points moving with consistent motions. We are exploring a dual approach to factorization, i.e., obtaining temporal clustering/segmentation by grouping together frames capturing consistent shapes. Temporal cuts are thus ...
I review the known approaches to two-body nonleptonic B meson decays, including factorization assumption, modified factorization assumption, QCD factorization, and perturbative QCD factorization. Important phenomenological aspects of these approaches are emphasized.
Quadrant Interlocking Factorization (QIF), an alternative to LU factorization, is suitable for factorizing invertible matrix A such that det(A) , 0. The QIF, with its application in parallel computing, the most efficient factorization technique yet underutilized. two forms of QIF among others, which are not only similar algorithm but also computation, WZ and WH differs applications properties. ...
Tensor factorization arises in many machinelearning applications, such knowledge basemodeling and parameter estimation in latentvariable models. However, numerical meth-ods for tensor factorization have not reachedthe level of maturity of matrix factorizationmethods. In this paper, we propose a newmethod for CP tensor factorization that usesrandom projections to ...
The non-negative matrix factorization (NMF) algorithm is a classical matrix factorization and dimension reduction method in machine learning and data mining. However, in real problems, we always have to run the algorithm for several times and use the best matrix factorization result as the final output because of the random initialization of the matrix factorization. In this paper, we proposed ...
QCD factorization for exclusive non-leptonic B-meson decays: General arguments and the case of heavy–light final states Abstract We provide a rigorous basis for factorization for a large class of non-leptonic two-body B-meson decays in the heavy-quark limit. The resulting factorization formula incorporates elements of the naive factorization approach and the hard-scattering approach , but allow...
