A semi-continuous segmental probability model, which can be considered as a special form of continuous mixture segmental probability model with continuous output probability density functions sharing in a mixture Gaussian density codebook, is proposed in this paper. The amount of training data required, as well as the computational complexity of the semi-continuous segmental probability model(S...

Human lives and organizations are increasingly dependent on the correct functioning of computer systems and their failure might cause personal as well as economic damage. There are two non-exclusive approaches to minimize the risk of such hazards: (a) faultintolerance tries to eliminate design and manufacturing faults for hardware and software before a system is put into service. (b) fault-tole...

Distributed denials of Service attacks (DDoS) have become one of the major threat on the internet. Most defence methods are focused on detecting DDoS attack on IP & TCP layer instead of application layer. With profiling of web browsing behaviour, the sequence order of web page request can be used for detecting Application layer DDoS (App_DDoS) attacks. Based on Hidden semi-Markov model (HsMM) ,...

High-throughput technologies like tiling array and next-generation sequencing (NGS) generate continuous homogeneous segments or signal peaks in the genome that represent transcripts and transcript variants (transcript mapping and quantification), regions of deletion and amplification (copy number variation), or regions characterized by particular common features like chromatin state or DNA meth...

background & aim: congenital hypothyroidism (ch) is one of the most common endocrine diseases and is a major cause of preventable mental retardation. early diagnosis of ch can help prevent future diseases. although time series techniques are often utilized to forecast future status, they are inadequate to deal with count data with overdispersion. the aim of this study was to apply poisson hidde...

Hidden semi-Markovmodels are a generalization of thewell-knownhiddenMarkovmodel. They allow for a greater flexibility of sojourn time distributions, which implicitly follow a geometric distribution in the case of a hidden Markov chain. The aim of this paper is to describe hsmm, a new software package for the statistical computing environment R. This package allows for the simulation and maximum...
