Artificial Intelligence (AI) is a branch of computer science focused on creating systems capable of performing tasks that would typically require human intelligence. These tasks include reasoning, learning, problem-solving, understanding natural language, recognizing patterns, and making decisions. AI systems can be categorized into two main types: narrow AI, which is designed for specific tasks (like voice recognition or image analysis), and general AI, which aims to replicate human cognitive abilities across a broad range of activities. AI utilizes various techniques, including Machine Learning, Deep Learning, neural networks, and natural language processing, to train models on data and improve their performance over time. The applications of AI are vast, impacting industries such as healthcare, finance, transportation, and entertainment, and are continually evolving as technology advances.
