PhD student in AI reliability

Noam Bires

I work on the reliability of deep neural networks under hardware-like faults, with a focus on software-implemented fault injection, modern vision models, and efficient evaluation methodologies. I am also interested in mechanistic interpretability: studying how models represent, process, and use information, and how those internal mechanisms affect safety.

Research

My current PhD work studies how deep neural networks behave when affected by hardware-like faults, and how to evaluate these effects with scalable software-based fault-injection workflows. I am also interested in mechanistic interpretability and model safety, especially how understanding internal model behavior can help make AI systems more reliable.

2025 - Present

PhD in Artificial Intelligence Reliability and Machine Learning

University of Rennes / IRISA / Inria, France

Research focus: reliability of deep neural networks under hardware-like faults using software-implemented fault injection, with applications to modern vision models and efficient fault-injection methodologies. I am also building an interest in mechanistic interpretability: how models think, what internal structures drive their decisions, and how this connects to safety.

TreeFI: Value-Aware Statistical Fault Injection for Deep Neural Networks

Noam Bires, Marcello Traiola, Angeliki Kritikakou, Elisa Fromont

IEEE/ACM International Conference on Computer-Aided Design (ICCAD 2026) · Upcoming presentation

TreeFI uses regression trees to group neural-network values by their response to bit flips and allocate fault injections where they matter most. Across the evaluated models, it reduces the required injection budget by up to 72.1× while preserving the target confidence and error margin.

Five stages of TreeFI: analyse value distributions, learn value intervals with regression trees, analyse interval frequencies, allocate fault injections, and aggregate outcomes to estimate the failure rate.

Personal

Outside research, I like keeping a few things in motion.

  • Competitive swimmer for most of my life.
  • Competitive beach volleyball, and sailing whenever I can.
  • Currently learning Chinese, slowly but seriously.
  • Reading with a deliberately random list. Recently: Italo Calvino, Dostoevsky, and Han Kang. I like walking into a bookstore, picking a random book, and discovering something new.
