This chapter discusses a variety of concepts in artificial intelligence (AI) technologies. The focus is primarily on large language models (LLMs), generative AI (GenAI) applications, and AI infrastructure.

What is Artificial Intelligence?

AI is an advanced transformative technology offering unparalleled capabilities to mimic human cognition and perform tasks that traditionally require human intelligence. 1 At its core, AI involves the development of systems that enhance machines’ abilities to learn from data and solve complex problems autonomously. With AI, systems can analyze large datasets to generate insights that drive innovation across industries. AI enables breakthroughs in computer vision, natural language processing, and robotics.

AI and machine learning (ML) are closely related fields, with ML being a subset of AI.2 AI refers to the broader concept of designing systems that can perform tasks requiring human intelligence. ML, on the other hand, is a specific approach within AI that focuses on building algorithms that direct computers to learn from data without being explicitly programmed. ML is an essential technique to achieve AI’s goals by allowing systems to learn from experience, adapt to new data, and make predictions or decisions based on that learning. ML algorithm training occurs on large datasets to recognize patterns, classify data, make predictions, or optimize processes, among other tasks. AI systems utilize the trained models to perform specific tasks or applications. Therefore, while AI encompasses broader goals and techniques to replicate human-like intelligence, ML is a foundational tool within AI.

Advances in AI have resulted in technological advancements, and are reshaping economies and societies, as well as how we live and work. AI-driven innovations are revolutionizing industries and disrupting traditional business models. AI applications are becoming increasingly pervasive, from personalized recommendations on e-commerce platforms to autonomous vehicles navigating city streets. However, as AI evolves, ethical considerations, such as bias, fairness, transparency, and accountability, are becoming critical concerns, highlighting the importance of taking a responsible approach to AI development and training. Ultimately, AI holds the potential to address some of the world’s most pressing challenges, from health care and climate change to education and economic inequality, ushering in a future where human ingenuity and machine intelligence collaborate to create a better world.

AI Taxonomy

AI taxonomy, also known as the classification or categorization of artificial intelligence, refers to the hierarchical organization of different types or categories of AI based on their capabilities, approaches, and functionalities. Table 1.1 presents a primary taxonomy of AI systems.

TABLE 1.1 AI Categorization

AI Category

Description

Narrow AI (Weak AI)

Narrow AI refers to AI systems designed to perform specific tasks or functions within a limited domain. These systems excel at particular tasks but need humans’ broad general intelligence. Examples include virtual assistants like Siri or Alexa, recommendation systems, and image recognition algorithms.

General AI (Strong AI)

General AI aims to replicate human-level intelligence and cognition across various tasks and domains. General AI can understand, learn, and adapt to different situations like humans. Achieving general AI is mainly theoretical.

Reactive AI

Reactive AI systems operate solely on current input without storing or referencing past experiences. They do not have memory or the ability to learn from previous interactions. While they can perform specific tasks well, they cannot adapt or improve over time.

Superintelligent AI

Superintelligent AI refers to AI systems that surpass human intelligence in all aspects. This hypothetical form of AI, often depicted in science fiction, possesses cognitive abilities far beyond those of humans and could outperform humans in every intellectual task.

Limited Memory AI

Limited memory AI systems, or transitional AI, can sometimes store and reference past experiences. Unlike reactive AI, these systems can learn from historical data and past interactions, allowing them to make better decisions or predictions based on previous experiences.

Theory of Mind AI

The theory of mind AI refers to systems that can understand and infer the mental states, beliefs, intentions, and emotions of others. This advanced form of AI enables machines to interact with humans and other entities more human-likely, understanding social cues and emotional context.

Self-aware AI

Self-aware AI, often considered the most advanced form of AI, refers to systems with consciousness and self-awareness, similar to humans. These systems have a sense of identity and subjective experiences.

While this taxonomy provides a broad overview of AI categories, it is essential to recognize that AI is a rapidly evolving field. New categories and classifications may emerge as research progresses and technology advances. Additionally, the boundaries between these categories are only sometimes clear-cut, and many AI systems may simultaneously exhibit characteristics of multiple categories.
