The AI Glossary

Artificial Intelligence (AI) can feel like a world full of cryptic terms and technical jargon. But it doesn’t have to be intimidating. Here’s a glossary of common AI terms, explained in plain language and ordered alphabetically for easy reference.

Algorithm

A recipe for computers. It’s a set of instructions that tells a machine how to solve a problem. Some are simple, like sorting numbers, while others are more like gourmet recipes, powering things like image recognition or voice assistants.

Artificial Intelligence (AI)

When machines can do tasks that normally require human intelligence, like recognizing speech, solving problems, or understanding language. It’s not magic—it’s math and data working behind the scenes.

Bias

When AI makes unfair or skewed decisions because the data it was trained on wasn’t balanced. For example, if an AI is trained only on photos of light-skinned people, it might struggle to recognize darker skin tones. It’s a reminder that AI is only as good as the data we give it.

Black Box

A term used to describe AI systems where the decision-making process isn’t clear. Even the developers sometimes don’t fully understand how the AI reaches its conclusions. It’s like magic, but for scientists, it’s a bit frustrating.

Chatbot

An AI-powered program that can carry on a conversation. Some are simple (like answering FAQs), while others are more advanced and can sound almost human. They’re the friendly helpers on many websites.

Computer Vision

AI’s ability to “see” and interpret images or videos. It’s how self-driving cars recognize stop signs and social media apps identify your friends in photos.

Data Set

A collection of data used to train AI. It could be anything from photos of dogs to medical records. The more diverse and accurate the data, the better the AI performs. Bad data? Bad AI.

Deep Learning

A supercharged version of neural networks. It uses many layers of nodes to learn complex patterns. This is how AI can do things like generate realistic photos or drive cars. Think of it as neural networks with a gym membership.

Ethics

The rules and principles guiding how AI should be used responsibly. It’s about making sure AI benefits people and doesn’t harm them, like ensuring privacy, fairness, and transparency.

Generative AI

AI that creates new content, like images, text, or even music. It’s behind tools that can write essays, generate artwork, or produce deepfake videos. Think of it as the creative side of AI.

Inference

This is when the AI applies what it has learned. If training is the study session, inference is the test. For example, after learning to identify cats, the AI can now tell if there’s a cat in a new photo.

Machine Learning (ML)

Think of it as teaching computers by example. Instead of programming exact rules, you feed the machine data, and it learns patterns on its own. It’s like showing a kid hundreds of pictures of cats until they can spot one in the wild.

Natural Language Processing (NLP)

The part of AI that understands and generates human language. It’s what powers chatbots, translates languages, and helps your voice assistant understand your requests. It’s like teaching machines to speak human.

Neural Network

Inspired by the human brain, a neural network is a system of “nodes” (like tiny digital neurons) that work together to process data. It’s what makes AI good at recognizing faces or predicting what you’ll want to watch next on Netflix.

Overfitting

When an AI learns too much from its training data and becomes like a perfectionist student who memorizes answers instead of understanding concepts. It performs well in practice but struggles with real-world problems.

Singularity

A sci-fi favorite. It’s the idea of a future where AI becomes smarter than humans. While it makes for great movies, it’s still firmly in the realm of speculation.

Training

The process of teaching AI by feeding it data. If AI is like a student, training is its study time. It goes through lots of examples, learns from them, and gets better at its task.

Turing Test

A test to see if a machine can fool a human into thinking it’s also human. Named after Alan Turing, one of the pioneers of AI. If a chatbot convinces you it’s real, it’s passed the test.

This glossary is a simple guide to the world of AI. By breaking down the terms in a straightforward way, it makes artificial intelligence a bit less daunting and a lot more interesting.
