2. Hidden Markov Models (HMMs)
HMMs are statistical models used in bioinformatics for various applications such as gene prediction and sequence analysis. They are characterized by:
- State Transition Probability: The probability of moving from one state to another.
- Emission Probability: The likelihood of observing a particular output from a given state.
3. Clustering Algorithms
Clustering is essential for grouping biological data based on similarities. Common clustering algorithms include:
- K-Means Clustering: A partitioning method that divides data into K clusters based on distance metrics.
- Hierarchical Clustering: A method that builds a hierarchy of clusters through either agglomerative or divisive approaches.
4. Machine Learning Algorithms
Machine learning techniques are increasingly applied in bioinformatics for predictive modeling and classification tasks. Notable algorithms include:
- Support Vector Machines (SVM): Used for classification tasks in genomics and proteomics.
- Random Forests: An ensemble learning method that improves prediction accuracy.
