Artificial intelligence (AI) functions by simulating human intelligence using advanced algorithms, data processing, and computational models. AI systems rely on machine learning, deep learning, and neural networks to analyze vast amounts of data, recognize patterns, and make intelligent decisions. How does AI work? In supervised learning, AI models are trained on labeled datasets, while unsupervised learning enables AI to identify hidden patterns within unstructured data. Reinforcement learning allows AI to improve performance over time through trial and error. AI applications include natural language processing (NLP) for chatbots, computer vision for image recognition, and automation for business processes. AI continuously learns and adapts, enhancing accuracy and efficiency in fields such as healthcare, finance, robotics, and cybersecurity, revolutionizing industries and improving everyday experiences.
