Artificial Intelligence (AI) is a branch of computer science focused on creating systems or machines that can perform tasks typically requiring human intelligence. This includes a variety of functions such as understanding natural language, recognizing patterns, solving problems, learning from experiences, and making decisions based on data. AI systems can be categorized into two main types: narrow AI, which is designed for specific tasks (like voice recognition or language translation), and general AI, which possesses the ability to understand, learn, and apply intelligence across a broad range of activities similar to a human. Techniques used in AI include Machine Learning, where algorithms improve through experience, and Deep Learning, which uses neural networks to process large amounts of data. The applications of AI are vast, impacting industries such as healthcare, finance, transportation, and entertainment, and continually expanding as technology advances.
