Co-Occurrence Statistic

AKA: Distributional Statistic, Co-occur.
Context:
- It can range from being a Local Co-occurrence Statistic to being a Global Co-occurrence Statistic.
- It can range from being a Linguistic Co-occurrence Statistic (such as lexical co-occurrence) to being a Visual Pattern Co-occurrence Statistic.
- It can be referenced by a Co-Occurrence Pattern.
- It can be related to a: Mutual Information Test, a Dice Coefficient, χ2 Test, a LSA-based Statistic Function, ...
Example(s):
- Co-Occurrence Count.
- Co-Occurrence Average.
- It can be a Domain-Specific Co-Occurrence Statistic, such as a Word Co-Occurrence Statistic, Citation Co-Occurrence Statistic.

One of the cues that helps recognition is global object co-occurrence statistics, a measure of which classes (such as chair or motorbike) are likely to occur in the same image together. …
