Machine Learning

Machine Learning Supervised Learning Classification (qualitative) K-NN Logistic Regression Neural Networks error analysis skewed data F1 score = 2PR/(P+R) accuracy precision recall learning curve SVM Kernal Parameters C sigma Regression (quantitative) Linear Regression validation sensitivity compactness Ensemble Learning decrease variance (bagging), bias (boosting), or improve predictions (stacking). The basic motivation of sequential methods is to exploit the dependence between the base learners. The basic motivation of parallel methods is to exploit independence between the base learners since the error can be reduced dramatically by averaging.
