To introduce the fundamentals of pattern recognition theory, the most common classification methods and the concept of neural networks. To enable the students to apply the learned methods to real data sets using MATLAB and WEKA.
- Notions and concepts: object, class, feature, data set, classifier, discriminant function classification region.
- Classification error, training and testing protocols.
- Classifier design. 1. Linear discriminant classifier (LDC). 2. Nearest mean classifier. 3. Rule-based classifiers. 4. k-Nearest Neighbour Classifier (k-nn). 5. Decision tree classifier 6. SVM. 7. Classifier ensembles.
- Hierarchical (agglomerative) clustering – nearest mean and nearest neighbour methods. K-means clustering
- Feature selection and extraction. Basic algorithms (sequential forward/backward selection, SVM recursive feature evaluation). Filter and Wrapper approaches.
- Single and multi-layer perceptron (MLP). The idea of error-back propagation training. RBF, SOM.
- Deep learning neural networks.
