Underfitting happens when a machine learning model is too simple to capture patterns in the data.It performs poorly on both training and test data because it fails to learn the…

Overfitting happens when a machine learning model learns not just the underlying patterns but also the noise in the training data.As a result, it performs very well on training data…

Model training is the process of teaching a machine learning algorithm to recognize patterns from data.During training, the model adjusts its internal parameters so it can make accurate predictions or…

Feature Engineering is the process of transforming raw data into meaningful, relevant features that help machine learning models learn better. In simple words:Better features = Better model performance. It is…

Data Preprocessing is the essential step of preparing raw, messy, incomplete, or inconsistent data before feeding it into a machine learning model. Since most real-world data contains errors or missing…

A dataset is a structured collection of data used to train, test, and validate machine learning models.It contains examples (rows) and features (columns) that help the model learn patterns and…

A Neural Network is a computational model inspired by how the human brain works. It consists of layers of connected nodes called neurons that process information and learn patterns from…

Deep Learning is a specialized branch of Machine Learning that uses artificial neural networks with many layers to learn from vast amounts of data. It mimics how the human brain…

Reinforcement Learning (RL) is a type of Machine Learning where an agent learns by interacting with an environment and receiving rewards or penalties based on its actions. Instead of being…

Unsupervised Learning is a Machine Learning technique where models learn patterns without labeled data.The system is not told what the correct output is—it must discover structure on its own. This…
