Machine Learning
Machine Learning is a subset of Artificial Intelligence (AI) that focuses on the development of algorithms and statistical models that enable computers to perform specific tasks without explicit instructions. Instead, these systems learn from data, identifying patterns and making decisions based on the information they have processed.
Machine learning is categorized into several types:
- Supervised Learning: Involves training a model on a labeled dataset, meaning the output is known. For example, a spam detection system that classifies emails as “spam” or “not spam” based on a labeled dataset.
- Unsupervised Learning: Involves training a model on data without labeled responses. For example, customer segmentation in Marketing, where the algorithm identifies distinct groups within the data without predefined categories.
- Reinforcement Learning: A type of learning where an agent learns to make decisions by taking actions in an environment to maximize some notion of cumulative reward. For example, training a game-playing AI to maximize its score by learning from trial and error.
Machine learning has various applications:
- Healthcare: Predicting patient outcomes based on historical data, such as diagnosing diseases from medical images.
- Finance: Fraud detection systems that analyze transaction patterns to identify suspicious activities.
- Self-driving Cars: Utilizing machine learning algorithms to interpret data from sensors and make driving decisions in real time.
