Which of the following is NOT considered an AI subfield according to the text?

Robotics is often considered a broader field that can include elements of artificial intelligence but is not itself a subfield of AI. It encompasses the design, construction, operation, and use of robots, which may incorporate various technologies, including sensors, control systems, and sometimes AI for tasks like automation and decision-making.

In contrast, machine learning and deep learning are explicitly subfields of AI. Machine learning involves algorithms that allow computers to learn from and make predictions or decisions based on data. Deep learning, a subset of machine learning, employs neural networks with multiple layers to analyze various data types, particularly useful in tasks like image and speech recognition. GEN AI, or Generative AI, is also considered a part of the AI landscape, focusing on creating new content based on learned patterns.

In essence, while robotics can utilize AI technologies, it operates as an interdisciplinary domain that can involve, but is not entirely defined by, artificial intelligence concepts.
