Machine learning in simple terms
In traditional programming, humans write explicit rules. In machine learning, a system learns patterns from examples and uses those patterns to make predictions or generate outputs.
| Concept | Meaning | Example |
|---|---|---|
| Data | Examples used for learning or input | Images, text, sales records |
| Model | Pattern structure learned from data | Classifier, language model, recommender |
| Training | Process of learning from data | Adjusting model behavior |
| Inference | Using the trained model | Answering a question or detecting an object |
| Evaluation | Testing usefulness and errors | Accuracy, bias, safety checks |
What AI is good at
AI can help with pattern recognition, text generation, translation support, image analysis, recommendations, anomaly detection, automation, summarization, and decision support.
What AI is not good at
AI can make mistakes, reflect bias in data, misunderstand context, generate confident wrong answers, overfit patterns, or fail in situations different from its training environment.
AI outputs should be reviewed carefully when they affect money, safety, law, health, education, employment, or personal rights.

AI questions
Not exactly. AI systems process data and patterns using mathematical models. Some outputs can look human like, but the internal process is different from human experience.
