Definition
Artificial intelligence is the branch of computer science focused on creating systems capable of performing tasks that normally require human intelligence. These tasks include learning, reasoning, problem solving, pattern recognition, natural language processing, and decision-making. AI systems can be narrow, designed for specific tasks, or general, intended to perform a broad range of cognitive activities.
AI is now a core driver of innovation in business and technology, powering applications from voice assistants to predictive analytics, automation, and robotics.
Advanced
At an advanced level, AI relies on algorithms, statistical models, and large datasets to simulate intelligence. Machine learning, a key subset, enables systems to improve performance over time without explicit programming. Deep learning, using neural networks with many layers, powers image recognition, speech understanding, and generative models.
AI is integrated into enterprise systems, cloud platforms, and edge devices. Advanced deployments involve reinforcement learning, explainable AI, and hybrid architectures combining symbolic reasoning with neural models.
