This paper shows a method to improve the language modeling for inflectional languages such as the Czech and Slovak language. Methods are based upon the principle of class-based language models, where word classes are derived from morphological information. Our experiments show that the linear interpolation with the class-based language models outperforms the stand-alone word N-gram language model...
In the 1960s E. Fama developed the efficient market hypothesis (EMH) which asserts that the financial market is efficient if its prices are formed on the basis of all publicly available information. That means technical analysis cannot be used to predict and beat the market. Since then, it was widely examined and was mostly accepted by mathematicians and financial engineers. However, the predictability...
One of the very important tasks, a computer network (or security) administrator has to fulfill under constructing a (distributed) firewall security policy, is to guarantee the absence of inconsistencies (or anomalies) and possibility to implement the policy in the given network configuration. The paper outlines an approach to verification of filtering rules of firewalls. The approach is intended for...
In this paper we're dealing with the problem of detecting malware using behaviour model. For better malware description we have divided this model into two parts — malware spreading model and malware statistical behavioural model. Spreading models are typical epidemiological models like SI model, advanced SIR and SEIR models and empiric file spreading model. In statistical behavioural model we're...
New technique for computer system Trojan diagnosis in monitor mode which uses fuzzy logic and allows improving reliability and efficiency is developed.
Individuals are not electrons. But in some situations, they behave very much alike. When it comes to many social and political questions, individuals' complex attitudes and beliefs must be boiled down to a simple yea (“spin up”) or nay (“spin down”). Although human societies, like physical materials, are very complex, some of their properties can be determined by understanding the interactions that...
FlexRay is an incoming standard for automotive distributed systems. For safety critical applications like x-by-wire systems it is necessary to develop techniques for their verification and validation. This paper presents a model of FlexRay Synchronization Mechanism, validation of this model and offers its usage for validation of parameters of synchronization mechanism in real FlexRay networks.
