Figure 2From: Evaluating the role of feedback regulation in recognition processingSimultaneous Pattern Recognition Test. The different recognition mechanisms are tested on simultaneous patterns. Such patterns are generated by combining multiple leaned patterns together and adding overlapping features. k represents the number of patterns combined simultaneously, below k is the number of compositions possible. 26 single patterns (k=1) and pattern mixes of up to 8 simultaneously (k=2 .. 8) are presented to networks that were trained on the single patterns. The vertical axis indicates the % of combinations where the top k most-active nodes corresponded with the test pattern mix. Only feedback regulation inherently recognizes simultaneous patterns without training on them.Back to article page
