### Predict Ads Click - Practice Data Analysis and Logistic Regression Prediction - Projects Based Learning

In this project we will be working with a data set, indicating whether or not a particular internet user clicked on an Advertisement. We will try to create a model that will predict whether or not they will click on an ad based off the features of that user. Welcome to this project on predict Ads Click in Apache Spark Machine Learning using Databricks platform community edition server which allows you to execute your spark code, free of cost on their server just by registering through email id. In this project, we explore Apache Spark and Machine Learning on the Databricks platform. I am a firm believer that the best way to learn is by doing.

### Regularization in Machine Learning - DataScienceCentral.com

This article was written by Prashant Gupta. One of the major aspects of training your machine learning model is avoiding overfitting. The model will have a low accuracy if it is overfitting. This happens because your model is trying too hard to capture the noise in your training dataset. By noise we mean the data points that don't really represent the true properties of your data, but random chance.

### Assumptions of Linear Regression -- What Fellow Data Scientists Should Know

Linear Regression is a linear approach to modeling the relationship between a target variable and one or more independent variables. This modeled relationship is then used for predictive analytics. Working on the linear regression algorithm is just half the work done. For linear regression to work on the given data, it is assumed that Errors (residuals) follow a normal distribution. Although this is not necessarily required when the sample size is very large.

### Machine Learning with Python

### Improving forecasting by learning quantile functions

The quantile function is a mathematical function that takes a quantile (a percentage of a distribution, from 0 to 1) as input and outputs the value of a variable. It can answer questions like, "If I want to guarantee that 95% of my customers receive their orders within 24 hours, how much inventory do I need to keep on hand?" As such, the quantile function is commonly used in the context of forecasting questions. In practical cases, however, we rarely have a tidy formula for computing the quantile function. Instead, statisticians usually use regression analysis to approximate it for a single quantile level at a time.

### Principal Component Regression -- Clearly Explained and Implemented

Principal Component Regression (PCR) is a regression technique that serves the same goal as standard linear regression -- model the relationship between a target variable and the predictor variables. The difference is that PCR uses the principal components as the predictor variables for regression analysis instead of the original features. The idea is that the smaller number of principal components represents most of the variability in the data and (presumptively) the relationship with the target variable. Therefore, instead of using all the original features for regression, we only utilize a subset of the principal components. Although the assumption of a relationship with the target variable does not always hold, it is often a reasonable enough approximation to yield good results.

### Deep Learning Prerequisites: Logistic Regression in Python

This course is a lead-in to deep learning and neural networks - it covers a popular and fundamental technique used in machine learning, data science and statistics: logistic regression. We cover the theory from the ground up: derivation of the solution, and applications to real-world problems. We show you how one might code their own logistic regression module in Python. This course does not require any external materials. Everything needed (Python, and some Python libraries) can be obtained for free.

### Mphasis

Now that we have an understanding of Baye's Rule, let's try to use it to analyze linear regression models. Where i is the dimensionality of the data X. Yj is the corresponding output for Xj. If i 3, Yj w1* x1j w2* x2j w3* x3j Where j is ranging from 1 to N where N is the number of data points we have. While the process of Bayesian modelling will be taken up in next part, let us consider the below model as true, for now.

### Intuitive Introduction to Logistic Regression (Understanding the mathematics behind the model)

I've been working with Logistic Regression to fit my data and make good predictions as a beginner. But as soon as I'm done with that I feel empty and the reason for that was simply because I was performing the same task iteratively (i.e. Just fitting and predicting which could get boring because of not understanding what's going on behind the scene). I've always thought of how is the model able to perform the predictions. But then I sat down one day and studied how the Logistic regression can perform its prediction.
