What is Machine Learning?
Machine learning represents a data analytics approach that harnesses artificial intelligence to emulate human learning from experience. Rather than depending on preset formulas, machine learning algorithms extract "knowledge" directly from data through computational methods. These algorithms identify inherent patterns within datasets that generate actionable insights and support improved forecasting and decision-making.
Why it matters
A key characteristic is their adaptive nature—as more training samples become available, the models continuously refine and enhance their accuracy, allowing systems to improve over time without explicit reprogramming.

Artificial intelligence (AI) is the simulation of human intelligence processes by machines, especially computer systems. AI employs sophisticated analysis and logic-based techniques—including machine learning—to interpret events, facilitate and automate decisions, and execute actions. This technology enables machines to understand, respond to, and learn with human-comparable levels of intelligence.
Automated machine learning (AutoML) is the process of automating the tasks of applying machine learning to real-world problems. The automation potentially encompasses every stage from beginning with raw datasets through feature engineering, model selection, deployment, and solution monitoring. More specifically, AutoML automates the selection, composition, and parameterization of machine learning models.
Predictive analytics employs data, statistical algorithms, and machine learning to assess the likelihood of future outcomes using historical information. Rather than merely documenting past events, it forecasts what will occur next, enabling executives and managers to adopt proactive, data-informed business strategies.
Explainable artificial intelligence (XAI) comprises processes and methods enabling users to comprehend and trust machine learning algorithm outputs. It describes AI models, their expected impact, and potential biases while characterizing model accuracy, fairness, transparency, and decision-making outcomes.
