    • Nonlinear Principal Component Analysis for Geographically Weighted Temporal‑spatial Data 

      Krzyśko, Mirosław; Łukaszonek, Wojciech; Ratajczak, Waldemar; Wołyński, Waldemar (Wydawnictwo Uniwersytetu Łódzkiego, 2018)
      Schölkopf, Smola and Müller (1998) have proposed a nonlinear principal component analysis (NPCA) for fixed vector data. In this paper, we propose an extension of the aforementioned analysis to temporal‑spatial data and ...
