Artificial Intelligence: What It Is and How It Works
Artificial intelligence refers to computer systems that perform tasks that typically require human judgment, such as recognizing patterns, understanding language, or making predictions.
Overview
What Is Artificial Intelligence?
Most practical AI today is based on machine learning, in which a model learns patterns from examples rather than following hand-written rules. Once trained, the model can make predictions or generate output for new inputs.
AI can be highly useful for specific, well-defined tasks. It can also make mistakes, reflect biases in its training data, and produce confident-sounding answers that are wrong — which is why human oversight remains important.
At a Glance
Learns patterns from data
Strong at specific, well-defined tasks
Output should be reviewed by people
Requires careful handling of data and privacy
Key Concepts
Terms and Ideas to Know
Machine Learning
Algorithms that improve at a task by learning from examples.
Training Data
The examples a model learns from; its quality strongly affects results.
Models
The trained system that turns inputs into predictions or generated content.
Generative AI
Models that create new text, images, or other content based on prompts.
Natural Language Processing
Techniques that allow computers to work with human language.
Bias & Fairness
Systematic errors that can arise when data or design does not represent people fairly.
Common Uses
Where Artificial Intelligence Is Used
Typical applications across organizations of different sizes and industries.
Drafting & summarizing
Producing first drafts and condensing long documents for review.
Classifying content
Sorting images, documents, or messages into categories.
Forecasting & anomalies
Estimating trends and flagging unusual patterns in data.
Support assistance
Helping answer common questions, with escalation to people.
