TLDR: Artificial intelligence (AI) is the intelligence of machines or software. It includes things like web search engines, recommendation systems, speech recognition, self-driving cars, and playing strategic games like chess and Go.
Artificial intelligence (AI) is all about making machines or software smart. It's like giving them a brain to think and make decisions, just like humans do. AI is used in many different ways, like helping us find information on the internet, suggesting videos or products we might like, understanding what we say to virtual assistants like Siri or Alexa, driving cars without a human driver, creating art, and even playing games like chess and Go at a really high level.
AI has been around for a long time, but it really started to take off in the 2010s when a technique called deep learning became really popular. Deep learning is a way for machines to learn from lots of examples and get better at tasks over time. This led to a big increase in funding and interest in AI.
There are different areas of AI research that focus on different goals and use different tools. Some of the goals include reasoning (solving problems step by step), knowledge representation (organizing and using information), planning (making decisions and taking actions), learning (improving performance on tasks), natural language processing (understanding and generating human language), perception (using sensors to understand the world), robotics (building intelligent machines), and social intelligence (making machines that can understand and respond to human emotions).
To achieve these goals, AI researchers use a variety of tools. They use search and optimization algorithms to find the best solutions to problems. They use logic to reason and make deductions. They use probabilistic methods to handle uncertainty and make predictions. They use classifiers and statistical learning methods to recognize patterns and make decisions. And they use artificial neural networks, which are inspired by the human brain, to learn from data and model complex relationships.
In summary, artificial intelligence is all about making machines or software smart. It's used in many different ways, from helping us find information to driving cars to playing games. AI researchers use different tools and techniques to achieve their goals, like search algorithms, logic, probabilistic methods, classifiers, and artificial neural networks.
