Stop Sign Detection Using Logistic Regression 

In this tutorial we will be using binary Logistic Regression for training a red color classifier in Python.

Logistic Regression Math & Geometrical Intuition with Example

Logistic Regression Math & Geometrical Intuition with Example. Logistic Regression is a Classifier which is used to solve the classification problems. As it’s technically dependent on the Linear Regression & Logit function is a method for a classification problem.

Logistic Regression for Binary Classification

In this article, we will use logistic regression to perform binary classification. Binary classification is named this way because it classifies the data into two results.

K-Nearest Neighbors Classification From Scratch

Step-by-Step Example in R Without Third-Party Libraries. This post aims to explore a step-by-step approach to create a K-Nearest Neighbors Algorithm without the help of any third-party library.

PyCaret: The Machine Learning Omnibus 

In this article, we will look at several arguments that can be passed to the `setup()` function to further control the preprocessing done by `pycaret`. By default the`setup` function requires only the dataframe and the target feature whose category labels we want to predict.

PyCaret: The Machine Learning Omnibus

..the one-stop-shop for all your machine learning needs. Starting with this Article, I will post a series on how pycaret helps us zip through the various stages of an ML project.

Performance Metrics for Classification Machine Learning Problems

Accuracy, Precision, Recall, F1 Score, ROC AUC, Log loss. Many learning algorithms have been proposed. It is often valuable to assess the efficacy of an algorithm.
