Eventizing Traditionally Opaque Binary Neural Networks as 1-safe Petri net Models
Summary
A new Petri net (PN)-based framework has been developed to model Binary Neural Networks (BNNs), which are typically opaque due to their discrete, non-linear behavior. This framework "eventizes" BNN operations, exposing causal relationships and dependencies for fine-grained analysis of concurrency, ordering, and state evolution. The approach constructs modular PN blueprints for core BNN components, including activation, gradient computation, and weight updates, then composes them into a complete system-level model. The composed PN is validated against a reference software-based BNN and formally verified for 1-safeness, deadlock-freeness, mutual exclusion, and correct-by-construction causal sequencing. Scalability and complexity are assessed at segment, component, and system levels using Workcraft's automated measurement tools, enabling causal introspection and formal verification for BNNs.
Key takeaway
For AI Scientists developing BNNs for safety-critical applications, this Petri net framework offers a pathway to overcome the inherent opacity of BNNs. You can achieve causal transparency and formal verifiability, which are essential for deployment in regulated or high-assurance domains. Consider integrating this event-driven modeling approach to establish behavioral guarantees and enhance trust in your BNN designs.
