Understanding the Basics of AI and Machine Learning
Defining Artificial Intelligence
Artificial intelligence (AI) refers to the development of computer systems that can perform tasks that typically require human intelligence, such as learning, reasoning, problem-solving, perception, and natural language understanding. AI has a wide range of applications in various fields, including healthcare, finance, transportation, education, and entertainment.
Machine learning (ML) is a subset of AI that involves training algorithms to learn from data, without being explicitly programmed. The goal of ML is to enable computer systems to improve their performance on a specific task over time, by learning from examples and experience. In other words, ML allows computers to automatically improve their performance, based on data and feedback.
There are several types of ML, including supervised learning, unsupervised learning, and reinforcement learning. Supervised learning involves training a model on labeled data, where the correct output is already known. Unsupervised learning involves training a model on unlabeled data, and allowing it to find patterns and relationships on its own. Reinforcement learning involves training a model through trial and error, by providing feedback in the form of rewards or penalties.
