On the Number of Observation Nodes in Recurrent Neural Networks with Linear Threshold and ReLU Functions
Liangjie Sun, Wai-Ki Ching, Tatsuya Akutsu
This paper investigates how node update rules and admissible state domains affect the minimum number of observation nodes required for global finite-horizon observability in recurr…

On the Observability and Controllability of Leaky-ReLU Networks
Liangjie Sun, Wai-Ki Ching, Shun-ichi Azuma +1
This paper studies minimum-node observability and controllability of Leaky rectified linear unit (Leaky-ReLU) networks under degree constraints. The objective is to characterize ho…
