Companion Research Directions for Masked Series Systems

Research ideas, ablation studies, and companion paper drafts building on the foundation paper:

Towell, A. (2025). Masked Causes of Failure in Series Systems: A Likelihood Framework. [arXiv/Zenodo forthcoming]

Research Directions in This Repo

Each directory contains a research brief, literature notes, and (eventually) draft content.

Directory Working Title Novelty Effort
weibull-masked-fim/ Closed-Form FIM for Weibull Series with Masked Failure Causes Medium High
deterministic-masking/ Information Recovery under Deterministic Masking — —

How to Use This Repo

  1. Each research direction has a brief.md with the core idea, scope, and open questions
  2. As ideas mature, they get promoted to their own paper repo
  3. Cross-reference the foundation paper’s theorems and notation throughout
