Cases

  • Article

A case is the set of all information known about a specific site user and consists of property/value pairs. This information may include user profile data, purchase history, click history, or a combination of these. Cases can also include any other data for which you require recommendations.

A typical analysis model uses between 10,000 and 50,000 cases with a resulting size of between 10 kilobytes (KB) and 100 KB.

In general, predictions are more accurate when many cases are available for a model. However, after a certain point (often 50,000 cases or less), there is little increase in accuracy when additional cases are used. In contrast, the time necessary to build an analysis model increases with the number of cases in the configuration.
