EXPRESS 2026 — Explainable and Reliable Software Systems
2nd Workshop, co-located with SPLASH/ISSTA 2026

Table of Contents

Overview

EXPRESS 2026 is the 2nd Workshop on Explainable and Reliable Software Systems, co-located with SPLASH/ISSTA 2026 in Oakland. Scope, in one line: dependability, safety, and reliability of software and agentic systems — verification, trustworthy AI, interpretability of ML models, and runtime observability all in-scope.

Sibling to SpecOps 2026 on the same week: SpecOps is about synthesizing and validating specs with foundation models; EXPRESS is about explaining and observing the resulting systems at runtime. The two workshops cover adjacent halves of the same problem — spec-driven build then explainable operate.

Adjacencies to current work

  • Reliability + agentic systems is one of the site's active threads (see also the ISSRE / QRS / DSC tracking discussion). EXPRESS explicitly names "agentic systems" in scope — closest workshop-scale fit for that thread.
  • Overlaps with the observability and runtime evidence research lines: runtime observability is in-scope.
  • Complementary to SpecOps (spec synthesis + validation) — attend/watch both if the schedule allows.

TODO

  • [ ] Refresh once accepted-paper list drops (~early August 2026, after Jul 31 notification).
  • [ ] Confirm exact workshop day within the Oct 3-9 window once program lands.
  • [ ] Cross-link to parent SPLASH/ISSTA 2026 index once program is finalized.
  • [ ] Watch for video/slides release; capture into the reliability + agents research index.
