摘要

在自然语言处理(NLP)、热力学和图像处理中存在着不同的状态,这在不同的层次上说明了最大熵模型(MEM)。最大熵原理用于近似基本概率分布的应用可以依赖于用于系统背诵的变量。在实时分布式系统(RTDS)中,到达时间、最坏情况执行时间和截止时间是实时任务的一些基本属性,它们阐明了整个系统的活动。众所周知,对于任务调度的验收测试(在实时调度算法中)和为了控制动态(任务迁移和复制),利用率是RTDS中发挥作用的唯一参数。所有这些方法都需要系统所有参与处理器的当前利用率值(=1)。据我们所知,本文首次引入了另一个具有很大亲和力的竞争者来代替利用因子。本文介绍了RTDS领域中的MEM,它的工作原理类似于利用率因子,但在可伸缩性和处理器信息方面具有一些额外的优势。在一些数学推导和理论例子的帮助下,我们想要传播熵可以是另一个参数,它可以并行地控制RTDS中的动态。

Visualization of Information Theoretic Maximum Entropy Model in Real Time Distributed System
There are various states of affairs in Natural Language Processing (NLP), Thermodynamics and Image processing, which illustrates the maximum entropy model (MEM) at different levels. An application of the principle of maximum entropy for approximation of fundamental probability distribution can depend on the variables that used for recitation of system. In Real Time Distributed System (RTDS) arrival time, worst-case execution time and deadline are some fundamental attributes of real time tasks that elucidate the activities of entire system. As we all know that for the acceptance test (in real time scheduling algorithms) of task scheduling and in order to govern the dynamics (task migration and duplication), utilization is the only parameter that brings into play in RTDS. All these methodologies need current utilization value (=1) of all participant processors of the system. To the best of our knowledge, this paper first time introduces one more contender that promises great affinity to replace utilization factor. This paper introduces MEM in RTDS arena that works analogous to the utilization factor with some additional advantages in terms of scalability and processor information. With the help of some mathematical derivations and theoretical examples, we would like to broadcast that entropy can be another parameter that is able to govern the dynamics in RTDS parallel to utilization factor.
