论文摘要

结合问题是阻止人工神经网络(ANN)对人类感知等世界的组成理解的基本挑战之一,因为当出现与多个对象的复杂数据时,生成因素的分离和分布式表示会干扰并导致歧义。在本文中,我们提出了一个受脑启发的杂化神经网络(HNN),该杂交神经网络(HNN)通过将尖峰时序动态(通过尖峰神经网络,SNN)与重建性关注(通过ANN)整合到ANN中,引入了临时结合理论。尖峰时序为分组提供了一个额外的维度,而重建反馈将尖峰协调为时间连贯状态。通过ANN和SNN的迭代相互作用,该模型在SNN编码空间中的替代同步触发时间连续绑定了多个对象。在二进制图像的合成数据集上评估模型的有效性。通过可视化和分析,我们证明了结合是可以解释的,柔软的,灵活的和分层的。值得注意的是,该模型是在单个对象数据集上训练的,而无需对分组进行明确监督,但成功地绑定了测试数据集上的多个对象,显示其组成概括能力。进一步的结果表明其在动态情况下的结合能力。

The binding problem is one of the fundamental challenges that prevent the artificial neural network (ANNs) from a compositional understanding of the world like human perception, because disentangled and distributed representations of generative factors can interfere and lead to ambiguity when complex data with multiple objects are presented. In this paper, we propose a brain-inspired hybrid neural network (HNN) that introduces temporal binding theory originated from neuroscience into ANNs by integrating spike timing dynamics (via spiking neural networks, SNNs) with reconstructive attention (by ANNs). Spike timing provides an additional dimension for grouping, while reconstructive feedback coordinates the spikes into temporal coherent states. Through iterative interaction of ANN and SNN, the model continuously binds multiple objects at alternative synchronous firing times in the SNN coding space. The effectiveness of the model is evaluated on synthetic datasets of binary images. By visualization and analysis, we demonstrate that the binding is explainable, soft, flexible, and hierarchical. Notably, the model is trained on single object datasets without explicit supervision on grouping, but successfully binds multiple objects on test datasets, showing its compositional generalization capability. Further results show its binding ability in dynamic situations.
