Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are designed to think and act like humans. The term "intelligence" encompasses reasoning, learning, problem-solving, perception, and language comprehension among other cognitive functions. AI systems can be categorized as either weak or strong; however, Strong AI—also known as Artificial General Intelligence (AGI)—is still a subject of ongoing research and has not yet been fully realized.
AI operates through algorithms that learn from data to make decisions with minimal human intervention. Machine learning is one subset of AI, where systems improve their performance at tasks over time without being explicitly programmed for each specific task they perform. Deep Learning—a further subfield within machine learning—employs neural networks with multiple layers (hence "deep") that can learn representations of data through a process called backpropagation.
AI has numerous applications across various industries, including healthcare diagnostics and treatment plans, autonomous vehicles for transportation systems, personalized recommendations in retail, predictive maintenance in manufacturing, fraud detection in finance, natural language processing (NLP) like chatbots or voice assistants such as Siri and Alexa.
Despite its many benefits, AI also raises ethical concerns regarding privacy invasion, job displacement due to autom
