What does "Continual Observation" mean?

Table of Contents

Continual observation refers to the process of watching and tracking changes in a dataset over time. In this context, it involves keeping an eye on data that can grow or shrink as new information comes in or old information is removed.

This is important when you want to analyze or group data, like finding patterns or clusters, while ensuring that the privacy of individuals is protected. When data updates occur frequently, you need methods that can quickly adapt to these changes without losing sight of privacy.

For example, if you have a group of people and their information changes—some join, some leave—you want to group them in a way that still keeps their personal details private. Using special techniques, it’s possible to do this in a way that balances accuracy and privacy, allowing for reliable analysis of ever-changing data.
