A System-Theoretic Approach to Hawkes Process Identification with Guaranteed Positivity and Stability
Xinhui Rong, Girish N. Nair
The Hawkes process models self-exciting event streams, requiring a strictly non-negative and stable stochastic intensity. Standard identification methods enforce these properties u…
