What is AI?

Artificial intelligence (AI) is not new. In fact, AI has been with us as an academic discipline since the 1950s. However, today, there remains no universally accepted definition.

Generally, AI refers to the development of computer systems that can perform tasks that would typically require human intelligence, such as learning, reasoning, perception, interacting with an environment, problem-solving, and even exercising creativity.

AI is not a single technology. Rather, it can be characterized as a set of technologies that includes any type of software or hardware component that enables machines to process and analyze large amounts of data, identify patterns, and make predictions or decisions based on that data.

There are several subcategories of AI including machine learning, federated learning, and deep learning; generative AI; natural language processing including both natural language generation and natural language understanding; speech recognition; computer vision; and expert systems. Intelligent automation, including robotic process automation (RPA), is not technically a form of AI. Instead, it works in conjunction with AI by automating repetitive processes in a quicker, more efficient way. The critical difference is that RPA is process-driven, whereas AI is data-driven. These subfields each focus on different aspects of AI, but they are all united by the goal of developing intelligent machines that can perform tasks without human intervention.

In recent years, the use of AI has been expanding. In fact, since 2017, the adoption of AI models in some industries has more than doubled, and investment has increased apace. With rapid evolution, there are inherent risks – some known and some unknown. Questions of ethical use, bias, and equity can be mitigated if initial data used to train these models are carefully selected and curated and humans are kept in the loop, especially when model outputs involve individual and population health and overall human welfare.

AI subcategory definitions

There are distinct differences between the terms AI and ML

Artificial Intelligence (AI) – An umbrella concept wherein machines are taught to perform tasks normally associated with human intelligence, such as decision-making and language interaction.

Machine Learning (ML) – A subset of AI dedicated to taking data and training algorithms to create models that can perform highly complex tasks without being explicitly programmed.

  • Deep Learning – A subset of ML that uses artificial neural networks to mimic the learning process of the human brain to solve complex problems.
    • Generative AI – A subset of deep learning that focuses on creating computer systems capable of generating new and original content, such as images, music, videos, or text.
    • Computer Vision – A subset of ML and deep learning that uses deep neural networks to interpret the meaning of images and videos to apply them to predictive or decision-making tasks.
  • Federated Learning – A subset of ML enabling an organization to train AI models on decentralized data without the need to centralize or share that data.
  • Natural Language Processing (NLP) – A subset of ML that enables computers to understand, analyze, and generate human language.
    • Natural Language Understanding (NLU) – A subset of NLP that focuses on understanding the meaning of text or speech.
    • Natural Language Generation (NLG) – A subset of NLP that focuses on the production of written or spoken language.
  • Speech Recognition – A subset of ML that uses algorithms to identify, understand, and process patterns in human speech.
  • Expert Systems – A subset of ML designed to emulate and mimic human intelligence, expert skills, or behavior in a particular field or topic.

Intelligent Automation (IA) – Technically not a form of AI or ML, IA uses automation technologies to perform repetitive process tasks with predictable inputs. It is used in combination with ML and NLP.

  • Robotic Process Automation (RPA) – A software technology and subset of IA that automates repetitive high-volume tasks by mimicking human behavior and speeding up processing time.
  • Business Process Management (BPM) – A management discipline that focuses on optimizing business processes using automation technologies.

AI classification

Generally, the degree to which an AI system can replicate human capabilities is used as the criterion to determine AI type.

AI and AI-enabled machines that can perform more human-like functions with equivalent or better levels of proficiency are considered a more evolved type of AI, while an AI that has limited functionality and performance is considered a simpler and less evolved type.

Based on this criterion, there are two ways in which AI is generally classified. One type is considered human-centric, while the other type is said to be technology-centric.

Myth-busting artificial intelligence

Breaking down the common misconceptions so you can focus on what is real

Myth: Only Big Tech uses AI

AI is present in many aspects of our everyday lives. Although large tech companies are usually the ones exploring AI research, we all interact with AI technology in our daily routines – even if we don’t always realize it. The hype and seeming explosion of generative AI has pushed AI to the front of corporate consciousness and is increasing the regularity of conscious AI usage.

What uses of AI exist in your organizational function today? Where else could AI be used?

Myth: AI will replace our jobs

Artificial intelligence is meant to work with humans, not instead of humans. AI is expected to augment human abilities, allowing us to work more efficiently and effectively. AI can take over repetitive and mundane tasks, allowing humans to focus on the creative, strategic, and interpersonal aspects of their work.

How will AI impact what your team does? How might you use the capacity that AI could generate?

Myth: AI is self-sufficient

Many people believe that all AI programs can exist and run entirely on their own. In fact, some work in AI still requires the human touch. AI algorithms are developed by humans, who inevitably have their own biases and preferences and, therefore, the data sets used by models may be biased as a result. Having the “human in the loop” helps to eliminate biases in the design process and strive to create diverse and inclusive data sets.

Have you thought about the impacts of tacit biases and the biases within your data sets?
