A Novel Variable-order Markov Model for Clustering Categorical Sequences
IEEE Transactions on Knowledge and Data Engineering, 2013 Clustering categorical sequences is an important and difficult data mining task. Despite recent efforts, the challenge remains, due to the lack of an inherently meaningful measure of pairwise similarity. In this paper, we propose a novel variable-order Markov framework, named weighted conditional probability distribution (WCPD), to model clusters of ...

Cell-related location area planning for 4G PCS networks with variable-order Markov model
Journal of Systems and Software, 2013 Abstract Location management is a critical issue in personal communication service (PCS) networks, tracking the location of user equipment (UE) with the goal of minimizing total signaling cost. Previous work can be classified into two categories: static and dynamic. Static schemes partition networks into fixed size LAs.

Segmented Sequence Prediction Using Variable-Order Markov Model Ensemble
IEEE Transactions on Knowledge and Data EngineeringIn recent years, sequence prediction, particularly in natural language processing tasks, has made significant progress due to advanced neural network architectures like Transformer and enhanced computing power. However, challenges persist in modeling and

Recognition of User Intentions for Interface Agents with Variable Order Markov Models
User Modeling, Adaptation, and Personalization, 2009 A key aspect to study in the field of interface agents is the need to detect as soon as possible the user intentions. User intentions have an important role for an interface agent because they serve as a context to define the way in which the agents can collaborate with users.

A Variable-Order Markov-Chain-Based Model for Rayleigh Fading and Rake Receiver
IEEE Signal Processing Letters, 2004 The reliability of usual Markov chain models for Rayleigh fading depends strongly on the channel variation regime. In this letter, a flat Rayleigh fading channel and RAKE receiver output model for all fading variation speeds is proposed. The complex Gaussian fading and the RAKE output processes are bandlimited.

Markov Models of Queueing–Inventory Systems with Variable Order Size
Cybernetics and Systems Analysis, 2017 Markov models of queueing–inventory systems with variable order size are investigated. Two classes of models are considered: with instant service and with nonzero service time. The model with nonzero service time assumes that impatient customers can form a queue of either finite or infinite length.

Parallel Problem Solving from Nature, 2016 This paper presents entropy-based population diversity measures that take into account dependencies between the variables in order to maintain genetic diversity in a GA for the traveling salesman problem. The first one is formulated as the entropy rate of a variable-order Markov process, where the probability of occurrence of each vertex is assumed to ...

CpG Island Identification with Higher Order and Variable Order Markov Models
, 2008 Identifying the location and function of human genes in a long sequence of genome is difficult due to lack of sufficient information about genes. Experimental evidence has suggested that there exists strong correlation between CpG islands and genes immediately following them.

, 2015 The growing demand for specialists in analyzing large volumes of data has led to an emerging profile of knowledge managers known as data scientists. How to address the different and complex scenarios with mathematical methods makes a difference when to apply them successfully in a dynamic environment such as the management indicators.
