Before diving into the complexities of machine learning and artificial intelligence, it’s crucial to understand what these terms mean and how they relate to each other.
What is Machine Learning?
Machine Learning is a subset of AI that focuses on the development of algorithms and statistical models that enable computer systems to improve their performance on a specific task through experience. In simpler terms, it’s about creating systems that can learn and make decisions with minimal human intervention.
What is Artificial Intelligence?
Artificial Intelligence is a broader concept that encompasses machine learning. It refers to the simulation of human intelligence in machines that are programmed to think and act like humans. AI systems can perform tasks that typically require human intelligence, such as visual perception, speech recognition, decision-making, and language translation.
The Relationship Between ML and AI
