Fast Radio Bursts (FRBs) are high-energy, transient phenomena with extremely short durations, and their origin remains uncertain. Various theories have been
proposed to explain their mechanism. Among these, FRB200428 has been confirmed to originate from the magnetar SGR 1935+2154, providing a potential model
for understanding other FRBs. In this study, we use the physical parameters of FRB200428 as a reference, assuming that the sources in the CHIME/FRB Catalog are
at the same distance. Based on this assumption, we compute the corresponding physical parameters for these sources. To analyze these data, we apply Uniform
Manifold Approximation and Projection (UMAP) for classification, aiming to determine whether other sources exhibit similar physical processes as FRB200428.
The CHIME/FRB Catalog offers a rich dataset, which includes both repeating and non-repeating FRBs. This study aims to reveal potential connections between
FRB200428 and other FRBs based on their shared physical characteristics.
