In search for the possible astrophysical sources behind origination of the diverse gamma-ray bursts, cluster analyses are performed to find homogeneous groups, which discover an intermediate group other than the conventional short and long bursts. However, very recently, few studies indicate a possibility of the existence of more than three (namely five) groups. Therefore, in this paper, fuzzy clustering is conducted on the gamma-ray bursts from the final ‘Burst and Transient Source Experiment’ catalog to cross-check the significance of these new groups. Meticulous study on individual bursts based on their memberships in the fuzzy clusters confirms the previously well-known three groups against the newly found five.

为了寻找各种伽玛射线爆发的背后可能的天体物理来源，进行聚类分析以发现均质基团，该均质基团发现了除了常规短脉冲和长脉冲外的中间基团。但是，最近很少有研究表明存在三个以上（即五个）组的可能性。因此，在本文中，对最终“爆发和瞬态源实验”目录中的伽马射线爆发进行了模糊聚类，以交叉检查这些新小组的重要性。根据各个突发在模糊聚类中的隶属关系进行的细致研究证实了先前众所周知的三组与新发现的五组之间的差异。
