How to solve binary classification problems using Bayesian methods in Python.Bayesian Thinking — OpenAI DALL-E Generated Image by AuthorIntroductionIn this article, I will build a simple Bayesian logistic regression model using Pyro, a Python probabilistic programming package. This article will cover EDA, feature engineering, model build and evaluation. The focus is to provide a simple framework for Bayesian logistic regression. Therefore, the depth of the first two sections will be limited. The code used in this article…

After a credit card? An insurance policy? Ever wondered about the three-digit number that shapes these decisions?IntroductionScores are used by a large number of industries to make decisions. Financial institutions and insurance providers are using scores to determine whether someone is right for credit or a policy. Some nations are even using social scoring to determine an individual’s trustworthiness and judge their behaviour.For example, before a score was used to make an automatic decision, a customer would go into a…

Optimizing performance using unstructured, real-world dataVardan Papikyan (Unsplash)Much has been written about the basics of Logistic Regression (LR) — its versatility, time-tested performance, even the underlying math. But knowing how to implement LR successfully and debug inevitable errors is much more challenging to do. That information lives deep in QA websites, academic papers, or simply comes with experience.The reality is, not every output will be as clean as the iconic iris dataset, swiftly classifying flower…

Let’s first start with a little bit brief explanation about the multinomial logistic regression and after this we will move on to the code implementation part by using different packages which are available in R.What is Multinomial Logistic Regression?Multinomial logistic regression is…

Statistics in R SeriesPhoto by Vladimir Fedotov on UnsplashIntroductionWe have covered logistic regression models for both binary and ordinal data and also demonstrated how to implement the model in R. Moreover the prediction analysis using the R libraries was also discussed in earlier articles. We have seen the impact of single as well as multiple predictors on the response variable and quantified it. Binary and ordinal response variables were taken to show how to deal with different types of data. In this article, we…

Statistics in R SeriesPhoto by Jen Theodore on UnsplashIntroductionWe have covered various types of logistic regression in the past several articles. The goal of all these models is to predict future data points as well as intermediate data points as accurately as possible. In this article, we will go through how this prediction analysis can be done in R for simple and multiple logistic regression using both binary and ordinal data.DatasetThe Adult Data Set that is available in the UCI Machine Learning Repository will be…

An introduction to multiclass logistic regression with theory and Python implementationDecision boundary of Logistic Regression. Image by author.ContentsThis post is a part of a series of posts that I will be making. Underneath you can see an overview of the series.1. Introduction to machine learning2. Regression3. ClassificationSetup and objectiveSo far we’ve gone over generative classifiers (QDA, LDA, and Naive Bayes), but now we’ll turn our eyes to a discriminative classifier: logistic regression. As mentioned in 3(a),…
