Abstract

Connectionist systems for spatio-temporal pattern recognition usually use a spatial coding of time or a mixed, spatial and temporal, representation. In this paper, we propose a temporal coding of spatial information by means of relative temporal delays of spatial events. These spatial events, translated into temporal events by scanning the 2D-space, feed a guided propagation network for handwritten records recognition. The network can adapt to (i) global pattern translation, (ii) local spatial shift of spatial events around their original position, (iii) suppression of some spatial events, and (iv) global pattern transformation.

适应二维空间扭曲的时空表征
用于时空模式识别的联结主义系统通常使用时间的空间编码或时空混合表示。本文提出了一种利用空间事件的相对时间延迟对空间信息进行时间编码的方法。这些空间事件通过扫描二维空间转化为时间事件,为手写记录识别提供引导传播网络。该网络能够适应(i)全球模式转换,(ii)空间事件在其原始位置附近的局部空间移动,(iii)某些空间事件的抑制,以及(iv)全球模式转换。
