Job Description

Thesis Subject

Context:
As machine learning systems become increasingly present in our everyday life, we require correctness guarantees in sensitive domains. The goal of the CertAI Project is to make progress in this direction, by exploiting certified model counting to certify machine learning output in restricted formal contexts.

Profile:
The goal of the advertised PhD position is to work on the intersection of model counting and machine learning, with the idea of substantially improving counting performance, based on recently established insights of normal forms for counting. We are looking for a highly motivated candidate with a strong interest in the theoretical and practical aspects of computer science, satisfiability, and/or model counting. Candidates should hold a Master's degree (or equivalent) in Computer Science or Applied Mathematics and possess the following skills: theoretical skills and/or implementation experience, preferably in the area of sat, model counting, or similar domains. Experience with theory and practice of machine learning is desirable.

Your Work Environment

The PhD will take place at CRIL (Lens Computer Science Research Center), an internationally renowned laboratory recognized for its cutting-edge expertise in Artificial Intelligence, particularly in the areas of knowledge representation, reasoning (SAT, constraints), and model counting. The PhD candidate will join a dynamic and respected team in these fields, benefiting from a stimulating research environment, expert supervision, and access to the hardware resources necessary for their work.
