In this lab, we will work on function of kernel that can take data as input and transform it into the required form in the kernels of the support vector machine (SVM).

**Module 26: Click-Through Prediction with Tree-Based Algorithms**

**Video 68_Decision Tree Classifier**

In this video, we are going to learn how we can build classification or regression models in the form of a tree structure that breaks down a dataset into smaller and smaller subsets while at the same time an associated decision tree is incrementally developed.

**Lab 70 Decision Tree Classifier**

In this lab, we will learn about the decision tree classifier which builds classification or regression models in the form of a tree structure and breaks down a dataset into smaller and smaller subsets while at the same time an associated decision tree is incrementally developed.

**Video 69_The Implementation of Decision Tree**

In this video, we will understand how we can implement a decision tree by making several predictions with criterion information for achieving the dataset in the Decision Tree.

**Lab 71 Random Forest banging a Decision Tree**

In this lab, we will be learning about the random forest banging a Decision tree which is an ensemble bagging algorithm to achieve low prediction error and also reduces the variance of the individual decision trees by randomly selecting trees and then either average them or picking the class that gets the most vote.

**Module 27: Click-Through Prediction with Logistic Regression**

**Video 70_Logistic Regression Classifier**

In this video, we’ll be discussing logistic regression which is basically a supervised classification algorithm. In this classification problem, the target variable(or output), y, can take only discrete values for a given set of features(or inputs), X.

**Lab 72 Working on Logistic Regression Classifier**

In this lab we will learn about the logistic regression classifier which classifies the target variable(or output), y, can take only discrete values for a given set of features(or inputs), X for the contrary to popular belief, logistic regression (IS) a regression model.

**Video 71_Click Through Prediction with Logistic Regression by Gradient Descent**

In this video, we will discuss click-through prediction which predicts clicks and works with logistic regression by using gradient Descent at where it preprocesses data, and the feature selection techniques would be done.

**Lab 73 Working on Feature Selection via Random Forest**

In this lab, we will work on feature selection via random forest which is a process of identifying only the most relevant features which are used by random forests naturally ranks by how well they improve the purity of the node.

**Module 28: Stock Price Prediction with Regression Algorithms**

**Video 72_Stock Price Prediction with Regression Algorithms**

In this video, we will learn how we can predict the future stock price with the technique, which provides relevant links by using several regressions and different algorithms in it.

**Lab 74 Predicting Stock Price with Regression Algorithms**

In this lab, we will work on predicting stock price with regression algorithms where the model overfits to the date and month column instead of taking into account the previous values from the point of prediction. The model will consider the value from the same date a month ago, or the same date/month a year ago while getting it.

**Video 73_Data Acquisition and Feature Generation**

In this video, we are going to learn about the Data acquisition by which we can gather signals from measurement sources and digitizing the signals for storage, analysis, and presentation on a PC and understand different feature generation.

**Video 74_Regression Performance Evaluation**

In this video, we will understand the regression performance against the ground truth at where we can evaluate it and compelled it to provide a necessary explanation regression performance evaluation.

**Module 29: Best Practices**

**Video 75_Best Practices**

In this video, we will work on different methods that we've learned like different regression, distributions, generations, and several methods.

**Lab 75 Best Practices in the Training Sets Generation Stage**

In this lab we will learn Best practices in the training sets generation stage with well-prepared data that is safe to move on with the generation stage with their redefined training sets.

**Lab 76 Best Practices in the Deployment and Monitoring Stage**

In this lab, we will work on the Best Practices in the Deployment and Monitoring Stage at where you deploy code. And, also it will ensure that you're sufficiently monitoring production for the metrics that matter to your engineers and your business.
