Stationarity of Time-Series on Graph via Bivariate Translation Invariance
Amin Jalili, Chong-Yung Chi
Stationarity is a cornerstone in classical signal processing (CSP) for modeling and characterizing various stochastic signals for the ensuing analysis. However, in many complex rea…

Translation Operator in Graph Signal Processing: A Generalized Approach
Amin Jalili, Sadid Sahami, Chong-Yung Chi
The notion of translation (shift) is straightforward in classical signal processing, however, it is challenging on an irregular graph structure. In this work, we present an approac…
