Part 1 ~ Machine Learning Algorithms Will Finally Make Sense After This In this video, we break down machine learning in the simplest way possible, not as a complex theory, but as a set of practical tools used to solve real-world problems. Starting from Linear Regression, we move through Logistic Regression, Decision Trees, Support Vector Machines, K-Nearest Neighbors, Dimensionality Reduction, Random Forest, K-Means Clustering, and Naive Bayes, understanding what each algorithm actually does, w

PCA Reduces High-Dimensional Data with Dimensionality Reduction | satheesh Sathish posted on the topic | LinkedIn

📊Dimensionality reduction in PCA (Principal Component Analysis) means reducing the number of variables (features) in your dataset while keeping as much important information (variance) as possible.📊 🌿 1. What does "dimensionality" mean? In data, each variable or feature is a dimension. Example: If you measure plant height, leaf number, and chlorophyll content, your data has 3 dimensions. ⚙️ 2. What is dimensionality reduction? It’s the process of converting a high-dimensional dataset (many va
