虽然复杂系统中事件相位的突变可能指示潜在的本质力量，但这种事件并不常见。在本文中，我们提出了一个基本事件提取器（E3）计划，以提取相对罕见的，但共同发生的事件序列的事件相变。在E3中，使用自组织映射（SOM）作为矢量量化（VQ）来编码非符号事件，并将KeyGraph作为共生图。然后，可以通过参考VQ的拓扑图上的发生密度估计来获得同现图上的事件转移。我们证明了E3使用声发射（AE）事件序列在燃料电池的损伤测试过程中观察到的，并获得合理的和必要的共同发生的损伤序列，表现出机械效应。
Although sudden changes of the event phase in complex system may indicate underlying essential forces, such events are not frequent. In the present paper, we propose an essential event extractor (E3) scheme to extract relatively rare but co-occurring event sequences in event phase transitions. In E3, the self-organizing map (SOM) is used as vector quantization (VQ) to encode non-symbolic events and KeyGraph as a co-occurrence graph. Afterwards, event transitions on the co-occurrence graph can be obtained by referring to an occurrence density estimation on the topology map of VQ. We demonstrate the E3using an acoustic emission (AE) event sequence observed during a damage test of fuel cells and obtain reasonable and essential co-occurring damage sequences that exhibit mechanical effects.
