Introduction Bayesian Networks (BNs) are probabilistic graphical models that represent a set of variables and their conditional dependencies using a directed acyclic graph (DAG). These models provide a way of representing complex relationships in data through conditional probabilities. Bayesian Networks have been widely used in various fields such as artificial intelligence (AI), machine learning…

Introduction The K-Nearest Neighbors (KNN) algorithm is one of the simplest and most intuitive machine learning algorithms used for classification and regression tasks. It is a non-parametric method, meaning it makes no assumptions about the underlying data distribution. Instead, KNN classifies new data points based on the majority class (for classification) or the average…

Introduction Stochastic Gradient Descent (SGD) is one of the most widely used optimization algorithms in machine learning, particularly for training large-scale models such as deep neural networks. SGD is an iterative method used to minimize a loss function by adjusting the model parameters in the direction of the negative gradient. This makes it an…

Introduction Principal Component Analysis (PCA) is a powerful statistical technique widely used for dimensionality reduction and feature extraction in machine learning. It is particularly useful when dealing with high-dimensional data, where the number of features can be overwhelming and may lead to challenges such as overfitting, computational inefficiency, and interpretability issues. PCA helps mitigate…

Introduction Gradient Boosting algorithms, such as XGBoost (Extreme Gradient Boosting) and LightGBM (Light Gradient Boosting Machine), are among the most powerful machine learning techniques used for both classification and regression tasks. These algorithms build strong predictive models by combining multiple weak models (usually Decision Trees) in an additive manner. They focus on minimizing errors…

Introduction Decision Trees and Random Forests are powerful machine learning algorithms widely used for both classification and regression tasks. These models are intuitive, easy to interpret, and capable of handling complex datasets with minimal preprocessing. While Decision Trees provide a simple and transparent approach, Random Forests enhance their performance by creating an ensemble of…

Introduction Support Vector Machines (SVMs) are powerful supervised machine learning models used primarily for classification and regression tasks. Introduced in the 1990s, SVMs have since become one of the most popular techniques in machine learning, known for their efficiency in handling complex, high-dimensional data. SVMs work by finding the hyperplane that best divides a…
