Abs t r ac t . Presence of irrelevant features is a fact of life in many realworld applications of classification learning. Although nearest-neighbor classification algorithms have emerged as a promising approach to machine learning tasks with their high predictive accuracy, they are adversely affected by the presence of such irrelevant features. In this paper, we describe a recently proposed c...

Abs ' t rae t In this paper , a class of algori thms for the problem of system identification in ~ are investigated. These algorithms are characterized by a two-stage structure and involve a class of window functions. Some conditions in terms of properties of the window functions are derived, which guarantee robust convergence of the algorithms. Identification errors are analyzed for several co...

Abs t ract . This paper presents a machine-independent study of parallel genetic algorithm performance. Our approach utilizes a dataflow model of computat ion in conjunction with Sisal, an implicit parallel programming language. We compare problem-solving power and runt ime efficiency for several parallel genet ic algorithms under uniform conditions. The proposed method makes it possible to ide...

Dengue virus (DENV) is the leading cause of arboviral diseases in humans worldwide. The envelope (E) protein of DENV is the major target of neutralizing antibodies (Abs). Previous studies have shown that a significant proportion of anti-E Abs in human serum after DENV infection recognize the highly conserved fusion loop (FL) of E protein. The role of anti-FL Abs in protection against subsequent...

Abs t rac t . A number of ideas concerning information-integration tools can be thought of as constructing answers to queries using views that represent the capabilities of information sources. We review the formal basis of these techniques, which are closely related to containment algorithms for conjunctive queries and/or Datalog programs. Then we compare the approaches taken by AT&T Labs' "In...

Objective(s): Pyocyanin is a blue-greenish redox-active pigment, produced by Pseudomonas aeruginosa, with a wide range of biological and biotechnological applications. Pyocyanin biosynthesis is regulated by the quorum-sensing (QS) system in which the expression of QS genes and QS-controlled virulence genes may be affected by serum as a complex medium. In the current study, effects of adult bovi...

روش های abs در سال 1984 توسط ابافی، برویدن و اسپدیکاتو مطرح شد. این روش ها نوعی روش مستقیم حل دستگاه خطی می باشند که در تکرار متناهی، حداکثر به تعداد معادلات، دستگاه را حل می کنند. این روش ها از سه پارامتر (به نام های مخترعین ) استفاده می کنند و انتخاب های این پارامترها الگوریتم های متفاوتی را به وجود می آورد. در این پایان نامه ابتدا به معرفی روش های abs و الگوریتم های مقیاس بندی شده آنها می پر...

This paper develops algorithms for high-dimensional stochastic control problems based on deep learning and dynamic programming. Unlike classical approximate programming approaches, we first the optimal policy by means of neural networks in spirit reinforcement learning, then value function Monte Carlo regression. is achieved recursion performance or hybrid iteration, regress now methods from nu...
