rEMM: Extensible Markov Model for Data Stream Clustering in R [PDF]

open access: yesJournal of Statistical Software, 2010
Clustering streams of continuously arriving data has become an important application of data mining in recent years and efficient algorithms have been proposed by several researchers. However, clustering alone neglects the fact that data in a data stream

STRIDE: A Sequencing Depth Robust Metric for Sparse Chromosome Conformation Capture Data Comparison. [PDF]

open access: yesAdv Sci (Weinh)
A mean first passage time (MFPT)‐based representation transforms sparse Hi‐C contact maps into robust topological representations, preserving biologically meaningful chromatin features and facilitating robust analysis of TADs, chromatin loops, differential chromatin contacts, and sparse single‐cell Hi‐C data.

Research on HMM based link prediction method in heterogeneous network

open access: yesTongxin xuebao, 2022
In order to solve the problem that incomplete mining of structural information and semantic information in heterogeneous networks, a link prediction method combining meta-path-based analysis and hidden Markov model was proposed for link prediction of ...

Deep Text Mining for Automatic Keyphrase Extraction from Text Documents

open access: yesJournal of Intelligent Systems, 2011
Due to existence of a huge amount of textual data either on the World Wide Web or in textual databases like PubMed, the development of novel automatic keyphrase extraction methods has emerged as one of the key research problems in recent past ...

Dynamic order Markov model for categorical sequence clustering

open access: yesJournal of Big Data, 2021
Markov models are extensively used for categorical sequence clustering and classification due to their inherent ability to capture complex chronological dependencies hidden in sequential data.

A Hidden Markov Model-based approach to sequential data clustering [PDF]

open access: yes, 2002
Clustering of sequential or temporal data is more challenging than traditional clustering as dynamic observations should be processed rather than static measures.

Operon Prediction Model Based on Markov Clustering Algorithm [PDF]

open access: yesInternational Journal Bioautomation, 2019
There are many operon prediction models, but few methods can be applied to the operon prediction of new sequencing species effectively. In this paper, an operon prediction model based on Markov clustering algorithm is proposed.

Compositional Approximate Markov Chain Aggregation for PEPA Models [PDF]

open access: yes, 2012
Approximate Markov chain aggregation involves the construction of a smaller Markov chain that approximates the behaviour of a given chain. We discuss two different approaches to obtain a nearly optimal partition of the state-space, based on different ...
