Induced and Restricted Representations of Kumjian--Pask Algebras of Higher-Rank Graphs
Bich Van Nguyen
In this paper, we develop a unified theory of induced and restricted representations for Kumjian--Pask (KP) algebras of higher-rank graphs (-graphs) over a unital commutative ri…

Spectral Stability of Pseudoinverse-Based Extreme Learning Machine
Bich Van Nguyen, Ngoc Anh Khong
Extreme Learning Machine (ELM) computes output weights analytically using the Moore-Penrose pseudoinverse. Although this leads to fast training, its numerical stability depends str…
