When it comes to data, there’s a lot that can go wrong. Whether it’s incorrectly labeling training data, or forgetting to include some important variables in your code, mistakes can happen a lot. But what if you could predict those mistakes before they happened? That’s the power of machine learning, and it’s exactly what we’re … Read more
Logistic regression is one of the most popular algorithm for classification problems. It is called regression even though it is not a regression algorithm because the underlying technique is similar to Linear Regression. The term “logistic” comes from the type of statistical model used (logit model). As seen in earlier releases classification algorithms are used … Read more
Let’s us try to implement logistic regression from scratch in python. Recommended to be read after the Neural Networks release. To test and run the code used check out: https://www.kaggle.com/code/tanavbajaj/logistic-regression-math-behind-without-sklearn Importing necessary libraries import numpy as np # linear algebra import pandas as pd # data processing, CSV file I/O (e.g. pd.read_csv) import matplotlib as … Read more

Classification algorithms depend on the dataset being used, and data scientists have curated various algorithms that can be used in certain situations. Most popular types of Classification Algorithms: Linear Classifiers Logistic regression Naive Bayes classifier Support vector machines Kernel estimation k-nearest neighbor Decision trees Random forests Let’s discuss this in more detail and understand when … Read more
Under supervised learning, there is a type called classification. These algorithms recognize the category a new observation belongs to based on the training dataset. In supervised learning, there are independent variables and a dependent variable Here, the dependent variable is the category, and each category’s features are independent variables. These categories are distinct and pre-defined … Read more
