Computer science is the holistic study of all aspects of computers, offering a generalist approach to topics ranging from algorithms and programming languages, to artificial intelligence (abbreviated as "AI") and machine learning. In short, artificial intelligence is a sub-discipline of computer science, and machine learning is a sub-discipline of artificial intelligence.

Once the realm of science fiction, decades of technological breakthroughs -- including OpenAI's release of ChatGPT-4 -- are bringing us closer to realizing artificial intelligence. Today, AI is often defined in two ways: first, as the scientific process of designing machines that are capable of human-like, inductive decision-making; and secondly, as the outcome, or the intelligence demonstrated by machines, in contrast to the natural intelligence displayed by humans and other animals.

The goals and functions of AI are similar to those of machine learning ("ML"), but they use a much wider range of techniques like deep learning, neural networks, robotics, and more. Machine learning is the science of designing autonomous ("self-thinking") software that can "learn" knowledge from big data to solve problems and make predictions at massive scale.

Educational requirements and employment pathways vary for careers across computer science, artificial intelligence and machine learning. That’s why it’s important to identify your personal career goals and interests before pursuing an advanced degree program.

What is Artificial Intelligence?

Artificial intelligence is a sub-discipline of computer science. AI, as a whole, tries to enable computers to mimic human intelligence in order to solve complex problems and make decisions at scale, in a replicable manner. By designing specialized algorithms, computer scientists help machines teach themselves, simulating human cognitive functions. AI-equipped machines are able to gather and process big data from various sources, such as sensors or remote inputs, rapidly analyze the data, and then act on the insight gathered from that analysis.

While it may be a decade or two before programming fundamentally changes, in the future software engineers will become designers, guiding AI as it writes code. Currently, there’s a tremendous shortage of programmers. This technology will help fill that gap and increase production.

The AI field draws upon computer science, mathematics, psychology, linguistics, philosophy and many others. Applications of artificial intelligence are innumerable, including healthcare and biomedicine, bioinformatics, physics, robotics, geosciences and more.

What is Machine Learning?

With AI/ML-related terms on the rise in job postings, many prospective students ask, how is machine learning similar to computer science, and is computer science the same as machine learning?

Machine learning is one sub-discipline of artificial intelligence, which seeks to "learn" knowledge from big data to solve complex problems in a replicable, scalable manner. Machine learning experts develop "next gen" algorithms -- machine learning-based algorithms -- that enable computer systems to automate the basic algorithms computer scientists and software engineers design and implement today, without the need for as much manual human intervention. Within companies, data scientists and other R&D/innovation teams then use these ML tools as one way to uncover actionable insights from massive amounts of data they have about their business, customers and competitive landscape.

Machine learning models promise greater precision, accuracy and efficiency, reducing much of the need for developers to manually program instructions for the machines. They're used daily to enhance decision-making in business, healthcare, law enforcement and finance. For example, machine learning algorithms are used for facial recognition, spam filters, and personalized search engine results.

What is Deep Learning?

Deep learning refers to the multi-stage machine learning methods in which machines learn representations of complex data in phases, over time. Deep learning is what it sounds like: a type of machine learning designed to delve much deeper than other forms of ML. Traditional machine learning algorithms are linear, whereas deep learning algorithms are stacked in a hierarchy of increasing complexity.

Over the past several years, thanks for the development of new machine learning (ML) training rules, massive computing capabilities, and enormous training datasets, deep learning systems have redefined the state-of-the-art in object identification, face recognition, and speech recognition. Examples of modern tools include ChatGPT, Deep Mind’s AlphaGo, Facebook’s Deep Face, and Baidu’s Deep Speech.

What is the Difference Between Artificial Intelligence and Machine Learning?

At a macro level, artificial intelligence (AI) is interested in enabling computers to mimic human intelligence in order to solve complex problems and make decisions at scale, in a replicable manner. Machine learning is one way to realize AI and focuses on training machines to learn from multiple data sources to solve complex problems in a replicable, scalable manner. In other words, machine learning is where a machine can learn from data on its own without being explicitly programmed by a software engineer, developer or computer scientist.

AI / ML vs Computer Science: Career Paths and Salary Potential

Professionals with broad, versatile computer science and data science skills continue to grow in workplace demand globally. Careers in computer science are expected to grow by +21% from 2021-2031 according to the U.S. Bureau of Labor Statistics, making it one of the fastest-growing and highest demand occupations -- and AI/ML-related occupations are growing even faster. With a master's degree in computer science or data science, students will be able to earn a median salary of $131,490 per year. The national average U.S. salary for a Machine Learning Engineer is $132,600. For AI Engineers, the average U.S. salary is approximately $156,648.

Also, because computer scientists' expertise extends well beyond individual programming languages, they're also well-positioned for the transition to machine learning based algorithms that negate the need for extensive manual coding and human-built software.

What’s the Difference in Career Paths between Computer Science vs Machine Learning and Artificial Intelligence?

Since computer science, AI and ML are core to the digital innovation transforming every industry, you'll find a broad range of tech, engineering and science roles requesting these skills.
