Artificial intelligence refers to machine learning, natural language processing and cognitive computing that enable machines to learn from data, recognize patterns and make intelligent decisions. AI improves automation, predictive analytics and decision-making processes across all industries. For example, AI-driven chatbots in customer service can handle the most frequent inquiries, reduce waiting times and improve satisfaction. AI speeds up decision-making by analyzing large data sets in real-time, reduces fraud, improves risk assessment and personalizes the customer experience. It increases productivity in industries such as banking, healthcare and e-commerce.
