Artificial intelligence (AI) and machine learning (ML) are terms that have created a lot of buzz in the technology world, and for good reason. They’re helping organizations streamline processes and uncover data to make better business decisions.
These technologies are responsible for capabilities like facial recognition features on smartphones, personalized online shopping experiences, virtual assistants in homes, and even the medical diagnosis of diseases.
What Is Artificial Intelligence?
Artificial intelligence is a poorly defined term, which contributes to the confusion between it and machine learning, says Bethany Edmunds, associate dean and lead faculty for Northeastern’s computer science master’s program.
“Artificial intelligence is essentially a system that seems smart. That’s not a very good definition, though, because it’s like saying that something is ‘healthy’. What exactly does that mean?” she says. “On a basic level, artificial intelligence is where a machine seems human-like and can imitate human behavior.”
These behaviors include problem-solving, learning, and planning, for example, which are achieved through analyzing data and identifying patterns within it in order to replicate those behaviors.

What Is Machine Learning?
Machine learning, on the other hand, is a type of artificial intelligence, Edmunds says. “Where artificial intelligence is the overall appearance of being smart, machine learning is where machines are taking in data and learning things about the world that would be difficult for humans to do,” she says. “ML can go beyond human intelligence.”
ML is primarily used to process large quantities of data very quickly using algorithms that change over time and get better at what they’re intended to do. A manufacturing plant might collect data from machines and sensors on its network in quantities far beyond what any human is capable of processing. ML is then used to spot patterns and identify anomalies, which may indicate a problem that humans can then address.
“Machine learning is a technique that allows machines to get information that humans can’t,” she says. “We don’t really know how our vision or language systems work—it’s difficult to articulate in an easy way. For this reason, we’re relying on data and feeding it to computers so they can simulate what they think we’re doing. That’s what machine learning does.”

Machine learning and deep learning are subfields of AI
As a whole, artificial intelligence contains many subfields, including:
Machine learning automates analytical model building. It uses methods from neural networks, statistics, operations research and physics to find hidden insights in data without being explicitly programmed where to look or what to conclude.
A neural network is a kind of machine learning inspired by the workings of the human brain. It’s a computing system made up of interconnected units (like neurons) that processes information by responding to external inputs, relaying information between each unit. The process requires multiple passes at the data to find connections and derive meaning from undefined data.
Deep learning uses huge neural networks with many layers of processing units, taking advantage of advances in computing power and improved training techniques to learn complex patterns in large amounts of data. Common applications include image and speech recognition.
Computer vision relies on pattern recognition and deep learning to recognize what’s in a picture or video. When machines can process, analyze and understand images, they can capture images or videos in real time and interpret their surroundings.
Natural language processing is the ability of computers to analyze, understand and generate human language, including speech. The next stage of NLP is natural language interaction, which allows humans to communicate with computers using normal, everyday language to perform tasks.
