How is Artificial Intelligence (AI) commonly defined?

Artificial Intelligence (AI) is commonly defined as machines exhibiting intelligence through different methodologies. This encompasses a wide range of techniques and approaches that allow machines to perform tasks that would typically require human intelligence. These methodologies can include machine learning, natural language processing, computer vision, and more, enabling machines to analyze data, learn from it, make decisions, and solve problems.

The definition captures the essence of AI, which is not limited to a singular form or application but rather includes various technologies and practices that facilitate intelligent behavior in machines. This broad understanding of AI allows for its application across multiple industries and use cases, from predictive analytics to automation and beyond.

In contrast, the other options focus on more limited interpretations of AI. Some suggest a narrow focus on human emotion or complex human-like forms, while others imply a restriction to robotic engineering, which does not encompass the full spectrum of AI applications. Thus, the choice that highlights the diversity of methodologies in AI is the most accurate representation of its definition.
