1. What Exactly Is Machine Learning?

Machine learning (ML) is a subset of artificial intelligence (AI) that focuses on enabling computers to learn from data without explicit programming. Instead of being explicitly programmed for specific tasks, machine learning algorithms recognize patterns, make predictions, and improve their performance over time through experience. According to a study by Stanford University, machine learning algorithms have demonstrated the ability to outperform humans in specific tasks, such as image recognition and fraud detection.

Supervised Learning: This involves training a model on labeled data, where the algorithm learns to map input features to known output labels.
Unsupervised Learning: This type of learning involves training a model on unlabeled data, where the algorithm identifies patterns and structures in the data without explicit guidance.
Reinforcement Learning: This involves training an agent to make decisions in an environment to maximize a reward signal.
