k-Means and Hierarchial clustering

k-Means and Hierarchical Clustering

Clustering is an unsupervised machine learning method used to group similar instances (data points) into clusters without having prior labels for these groups. The idea is that data in one cluster is more similar to each other than to those in other clusters. Let’s delve into two of the most popular clustering algorithms: k-Means and…

Decision trees & Random forests

Decision Trees Decision Trees are a popular machine learning algorithm used for both classification and regression tasks. They are a non-parametric supervised learning method. Basic Structure: How Decision Trees Work: Algorithm to Build a Decision Tree (like CART – Classification and Regression Trees): Strengths: Limitations: Random Forests Random Forests is an ensemble learning method that…

Machine learning: Neural Networks

Neural networks, particularly artificial neural networks (ANNs), are a foundational element of modern artificial intelligence and machine learning. They are algorithms inspired by the structure and function of the brain’s biological neural networks. The primary aim of a neural network is to recognize patterns, which makes them particularly effective for tasks such as classification, regression,…

Logistic Regression in machine learning

Logistic Regression is a statistical method and a fundamental classification algorithm in machine learning used for predicting the probability of a given instance belonging to a particular category in a binary or multi-class classification problem. Basic Idea: While linear regression predicts a continuous outcome, logistic regression predicts a probability that the given instance belongs to…
