Among the advanced ARPES techniques, spatially-resolved ARPES has recently attracted growing interest because of its capability to obtain local electronic information at the micro- or nano-metric length scales by utilizing a well-focused light source [1]. On the other hand, it is not trivial to analyze and understand the spatial variation of electronic states against massive datasets, typically in 4-dimensional space (energy, momentum, and two spatial axes). In this work, we present unsupervised clustering analyses based on K-means and Fuzzy-c-means methods on spatially-resolved micro-ARPES data from Y-based high-Tc cuprate superconductor YBa2Cu3O7-δ, which shows spatial inhomogeneity due to multiple surface terminations due to BaO or CuO layers on a cleavage (001) plane [2]. The performance of the clustering analyses will be demonstrated with the comparison of the conventional analysis method.\n[1] Hideaki Iwasawa, Electronic Structure 2, 043001 (2020).\n[2] H.
