Lecture 9: Evaluation and Multi-class Classification
** Evaluation
* Supervised evaluation
* Comparing algorithms
* Idea 1
* Is model 2 better?
* Comparing scores: significance
* Idea 2
* Variance
* Repeated experimentation
* n-fold cross validation
* k-fold cross validation
* Leave-one-out cross validation
* Comparing systems: sample 1
* Comparing systems: sample 2
* Comparing systems: sample 3
* Comparing systems
* Comparing systems: sample 4
* Statistical tests
* F1-Score (F-Score)
* t-test
* Calculating t-test
* p-value
* Statistical tests on test data
* Bootstrap resampling
* Experimentation good practices
** Multiclass
* Multiclass classification
* Real world multiclass classification
* Multiclass: current classifiers
* k-Nearest Neighbor (k-NN)
* Decision Tree learning
* Perceptron learning
* Black box approach to multiclass
* Approach 1: One vs. all (OVA)
* OVA: linear classifiers (e.g. perceptron)
* OVA: classify
* OVA: classify, perceptron
* Approach 2: All vs. all (AVA)
* AVA training visualized
* AVA classify
* OVA vs. AVA
* Approach 3: Divide and conquer
* Multiclass summary
* Multiclass evaluation
* Multiclass evaluation imbalanced data
* Macro averaging vs. micro averaging
* Confusion matrix
