Abstract¶
OACT is an open-source, public-data decision-support prototype designed to help stakeholders detect, investigate, and quantify infrastructure disruption risk during extreme weather events (e.g., flooding and atmospheric river scenarios). This talk presents a reproducible “Right to Replicate” architecture: public data ingestion, auditable transformations, transparent scoring, and an evidence-first workflow designed for responsible reuse by universities and public-sector partners.
We will walk through the end-to-end pipeline (signals → features → risk scoring → recommended actions) and highlight design choices that improve reproducibility and governance, such as dataset lineage, assumptions logging, and decision traceability. By focusing on “auditability by default,” OACT addresses the critical gap between opaque proprietary risk models and the need for transparent, accessible tools in public-sector resilience planning. Attendees will leave with a concrete pattern for building analytics prototypes that bridge research, open infrastructure, and real-world decision needs.

Yidan (Lena) Hu | Independent Researcher¶
Yidan (Lena) Hu is the Lead Data Scientist for the Open Analytics Control Tower (OACT), where she leads the design and implementation of the system’s risk modeling framework, focusing on translating compound environmental signals into predictive, decision-ready indicators of infrastructure disruption. In her professional career, Lena is a senior-level data scientist in a top-tier tech company, specializing in large-scale analytics and machine learning systems within the media and entertainment industry. Her current independent research establishes a reproducible, auditable methodology for operational risk intelligence, directly supporting public-sector resilience efforts and aligning with federal and state priorities for critical infrastructure protection.
