Area of Science:

  • Bioinformatics and Computational Biology
  • Genetics and Genomics
  • Biostatistics

Background:

  • Hidden Markov Models (HMM) are powerful probabilistic tools for sequence data analysis.
  • Existing HMM reviews often lack biological context, focusing on general signal processing.
  • Gregor Mendel's 1866 work on plant hybridization laid the foundation for modern genetics, introducing the concept of 'Elemente' (genes).

Purpose of the Study:

  • To present the theory and algorithms of Hidden Markov Models (HMM) using biological examples.
  • To introduce the "mendelHMM" toolbox for applying HMMs in a biological context.
  • To demonstrate the intuitive advantages of HMMs in biological and bioinformatical settings.

Main Methods:

  • Explanation of HMM background, theory, and algorithms.
