On the Estimation of Mutual Information
نویسندگان
چکیده
The mutual information is useful measure of a random vector component dependence. It is important in many technical applications. The estimation methods are often based on the well known relation between the mutual information and the appropriate entropies. In 1999 Darbellay and Vajda [3] proposed a direct estimation methods. In this paper we compare some available estimation methods using different 2-D random distributions. Abstrakt: Vzájemná informace je hojně už́ıvanou mı́rou vzájemné závislosti jednotlivých složek v́ıcerozměrných náhodných vektor̊u. Časté uplatněńı nacháźı předevš́ım v inženýrských aplikaćıch. Metody odhadu vzájemné informace většinou vycháźı ze známého vztahu mezi vzájemnou informaćı a entropiemi př́ıslušných rozděleńı, ale vzájemnou informaci je možné odhadnout také př́ımo. Na př́ıkladech r̊uzných typ̊u dvojrozměrných rozděleńı srovnáme některé dostupné metody odhadu vzájemné informace.

On Classification of Bivariate Distributions Based on Mutual Information
Among all measures of independence between random variables, mutual information is the only one that is based on information theory. Mutual information takes into account of all kinds of dependencies between variables, i.e., both the linear and non-linear dependencies. In this paper we have classified some well-known bivariate distributions into two classes of distributions based on their mutua...
متن کاملA Novel Subsampling Method for 3D Multimodality Medical Image Registration Based on Mutual Information
Mutual information (MI) is a widely used similarity metric for multimodality image registration. However, it involves an extremely high computational time especially when it is applied to volume images. Moreover, its robustness is affected by existence of local maxima. The multi-resolution pyramid approaches have been proposed to speed up the registration process and increase the accuracy of th...
متن کاملResearch of Blind Signals Separation with Genetic Algorithm and Particle Swarm Optimization Based on Mutual Information
Blind source separation technique separates mixed signals blindly without any information on the mixing system. In this paper, we have used two evolutionary algorithms, namely, genetic algorithm and particle swarm optimization for blind source separation. In these techniques a novel fitness function that is based on the mutual information and high order statistics is proposed. In order to evalu...

متن کاملA New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks
The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...
متن کاملPerformance Evaluation of Closed Ended Mutual Funds in Pakistan
Mutual funds are the best tool to mobilize savings and investments in an economy and Pakistan is the pioneer in South Asia, but this industry is not as much mature in comparison to its age in Pakistan. This paper examines the performance of closed ended mutual funds in Pakistan by using five different ranking measures during a period of January 2009 to December 2013 and the sample consists of o...
