  20. Overview of Machine Learning Copyright © 2018, edureka and/or its affiliates. All rights reserved.

  21. Machine Learning Machine learning is a type of Artificial Intelligence that allows software applications to learn from the data and become more accurate in predicting outcomes without human intervention. Copyright © 2018, edureka and/or its affiliates. All rights reserved.

  24. Supervised Learning Supervised Learning is where you have input variable (X) and output variable (Y) and you use an algorithm to learn the mapping function from the input to the output. Y = f(X) ALGORITHMS: Logistic Regression Decision Tree Linear Regression Naïve Bayes Classifier Random forest Copyright © 2018, edureka and/or its affiliates. All rights reserved.

  26. Logistic Regression ❑ Logistic regression produces results in a binary format ❑ Used to predict outcome of a categorical dependent variable ❑ Outputs – Yes/ no, true/ false, high/ low, pass/ fail Relation Between Dependent & Independent variable: Unknown value of variable or the variable to be predicted known variable or the variable related to dependent variable Dependent Variable Independent Variable Y = a + bX Y It is the tangent angle made by the line It is a point at which the line cuts the y- axis Slope intercept Copyright © 2018, edureka and/or its affiliates.

  27. Demo: Logistic Regression PROBLEM STATEMENT A car company has released a new SUV in the market. Using the previous data about the sales of their SUV’s, they want to predict the category of people who might be interested in buying this. Copyright © 2018, edureka and/or its affiliates.

  29. Unsupervised Learning Unsupervised Learning is the training of a model using information that is neither classified or labelled. Unsupervised learning is also called as clustering analysis.

  31. Reinforcement Learning It is an area of machine learning where a RL agent learns from the consequences of its actions, rather than from being taught explicitly. It selects its actions on basis of its past experiences (exploitation) and also by new choices (exploration). ALGORITHMS: Q- learning SARSA DQN Copyright © 2018, edureka and/or its affiliates.
