Ensemble coding

Ensemble Coding

Ensemble coding, also known as ensemble perception or summary representation, is the ability to see the average of a group of objects or faces.

Ensemble Coding Defined

In a 2018 Annual Review of Psychology, Whitney and Lieb provided an operational definition of ensemble coding.

"A flexible operational definition of ensemble coding should include the following five concepts:

• Ensemble perception is the ability to discriminate or reproduce a statistical moment.

• Ensemble perception requires the integration of multiple items.
• Ensemble information at each level of representation can be precise relative to the processing of single objects at that level.
• Single-item recognition is not a prerequisite for ensemble coding.
• Ensemble representations can be extracted with a temporal resolution at or beyond the temporal resolution of individual object recognition.” ^[2]
