Job Description
Thesis Subject
The objective of the PhD project is to advance the theory and methodology of majorisation-minimisation (MM), with a focus on problems from signal/image processing or machine learning. MM consists in iteratively building and minimising a locally tight upper bound of the loss function. In other words, it resorts to the iterative optimisation of a local approximation. This is an intuitive and yet powerful optimisation framework that does not require stringent assumptions. MM algorithms decrease the value of the loss at every iteration and well-designed upper bounds can finely capture the local curvature of the loss, resulting in efficient updates. Though MM can be traced back to the 1970s, it has enjoyed a significant revival in the last years. It subsumes well-known algorithms such as (Bregman) proximal gradient methods, Expectation-Maximisation (EM) or the Concave-Convex Procedure (CCP).
A more precise research program will be defined in accordance with the successful candidate.
Topics of interest include: acceleration of MM algorithms, convergence of MM, generalised MM, unrolled MM.
Problems of interest include: inverse problems, optimal transport, matrix factorisation.
Your Work Environment
The successful candidate will join the Institut de Recherche en Informatique de Toulouse (IRIT), a joint laboratory of CNRS and Toulouse universities & engineering schools (ENSEEIHT campus). The position is funded by Toulouse AI institute ANITI (AMINA chair).
