2 Goals Overview of machine learning Machine learning models & techniques available in MATLAB MATLAB as an interactive environment for evaluating and choosing the best algorithm 2

3 What is Machine Learning? Algorithms and techniques used for data analytics (think data analysis) Obtain valuable information from the data Why is it called learning? Systems learn from initial training data Use resulting model (or knowledge) to predict outcomes or classes of new samples MPG Acceleration Displacement Weight Horsepower MPG Acceleration Displacement Weight Horsepow er 3

4 Machine Learning Characteristics and Examples Characteristics Lots of data (many variables) System too complex to know the governing equation (e.g., black-box modeling) Examples Pattern recognition (speech, images) Financial algorithms (credit rating, algorithmic trading) AAA AA 93.68% 2.44% 5.55% 92.60% 0.59% 4.03% 0.18% 0.73% 0.00% 0.15% 0.00% 0.00% 0.00% 0.00% 0.00% 0.06% A 0.14% 4.18% 91.02% 3.90% 0.60% 0.08% 0.00% 0.08% Energy forecasting (load, price) BBB BB 0.03% 0.03% 0.23% 0.12% 7.49% 0.73% 87.86% 8.27% 3.78% 86.74% 0.39% 3.28% 0.06% 0.18% 0.16% 0.64% Biology (tumour detection, drug discovery) B CCC D 0.00% 0.00% 0.00% 0.00% 0.00% 0.00% 0.11% 0.82% 9.64% 85.37% 2.41% 0.00% 0.37% 1.84% 6.24% 81.88% 0.00% 0.00% 0.00% 0.00% 0.00% 1.64% 9.67% % AAA AA A BBB BB B CCC D 4

5 Challenges Machine Learning Significant technical expertise required No one size fits all solution Locked into Black Box solutions Time required to conduct the analysis 5

6 Overview Machine Learning Type of Learning Categories of Algorithms Unsupervised Learning Clustering Machine Learning Group and interpret data based only on input data Supervised Learning Develop predictive model based on both input and output data Classification Regression 6

7 Unsupervised Learning k-means, Fuzzy C-Means Hierarchical Clustering Neural Networks Gaussian Mixture Hidden Markov Model 7

8 Supervised Learning Regression Neural Networks Decision Trees Ensemble Methods Non-linear Reg. (GLM, Logistic) Linear Regression Classification Support Vector Machines Discriminant Analysis Naive Bayes Nearest Neighbor 8
