人脸识别的实证研究表明，人脸可能是通过一些典型的表征存储在记忆中。然而，这些规范表示的性质尚不清楚。虽然心理学数据显示四分之三视角的优势，但生理学研究表明，侧面和正面的观点是储存在记忆中的。提出了一种计算方法来调和这些结果。当不同的意见，或意见的组合，被用作一个两阶段的识别网络组成的自联想记忆，然后由径向基函数网络的内部表示时，得到的结果的模式进行比较。结果表明，（i）正面和侧面视图足以达到最佳的网络性能;（ii）所有不同的表示产生四分之三的视图优势，类似于一般描述的人类受试者。这些结果表明，虽然四分之三视图比其他视图产生更好的识别，但它们不需要存储在内存中来显示这种优势。
Empirical studies of face recognition suggest that faces might be stored in memory by means of a few canonical representations. The nature of these canonical representations is, however, unclear. Although psychological data show a three-quarter-view advantage, physiological studies suggest profile and frontal views are stored in memory. A computational approach to reconcile these findings is proposed. The pattern of results obtained when different views, or combinations of views, are used as the internal representation of a two-stage identification network consisting of an autoassociative memory followed by a radial-basis-function network are compared. Results show that (i) a frontal and a profile view are sufficient to reach the optimal network performance; and (ii) all the different representations produce a three-quarter view advantage, similar to that generally described for human subjects. These results indicate that although three-quarter views yield better recognition than other views, they need not be stored in memory to show this advantage.
