Models for perceptual grouping and contour integration are presented. Connection weights depend on distances and angle differences, while neurons evolve following a spiking dynamics (Izhikevich's model in most of the considered cases). Although the studied synapses depend on discrete three-valued functions, simulations display the emergence of approximate synchrony, making these cognitive tasks possible. Noise effects are examined, and the possibility of achieving similar results with a different neuron model is discussed.
本文提出了用于感知分组和轮廓整合的模型。连接权重取决于距离和角度差异,而神经元则遵循脉冲动力学进行演化(在大多数考虑的情况下采用艾兹海默模型)。尽管所研究的突触依赖于离散的三值函数,但模拟显示出近似同步的出现,使得这些认知任务成为可能。研究了噪声效应,并讨论了使用不同神经元模型获得类似结果的可能性。
