  52. 52. What is Machine Learning?
  53. 53. What is Machine Learning? Machine Learning is a process by which computers find patterns in data Makes those patterns available to applications. Application can then gain insights on new data based on conformity to the identified patterns.
  54. 54. Why Machine Learning? Enables you to learn from data faster than humans and make decisions on new events. Power of ML comes from the information that we can extract from existing data in the system. Enables to find patterns that are not obvious to humans. It can self adapt to new events.

  65. 65. Common Classes of Algorithms Classification Regression Anomaly Detection Clustering
  66. 66. Identifying to which of a set of categories (sub-populations) a new observation belongs, on the basis of a training set of data containing observations (or instances) whose category membership is known. Classification A set of statistical processes for estimating the relationships among variables. It includes many techniques for modeling and analyzing several variables, when the focus is on the relationship between a dependent variable and one or more independent variables (or 'predictors’). Regression The task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar (in some sense) to each other than to those in other groups (clusters). Clustering The identification of items, events or observations which do not conform to an expected pattern or other items in a dataset. Typically the anomalous items will translate to some kind of problem such as bank fraud, a structural defect, medical problems or errors in a text. Anomaly Detection Common Classes of Algorithms
  67. 67. Supervised vs Unsupervised Learning Unsupervised Learning • Unlabeled Data • Clustering (K-means) • Market Basket Analysis (Apriori Algorithm) • Anomaly Detection (Extreme Studentized Deviate Test) • Text mining (Latent Dirichlet Allocation) Supervised learning • Labeled Data • Anomaly Detection (Support Vector Machine) • Text mining (Support Vector Machine) • Regression (Linear Regression) • Classification (Random Forest) • Sentiment analysis (Neural Network)
