Intership Agentic Multimodal ai For Understanding And Reasoning Over Complex Technical Documents H/F - CEA

Le CEA est un acteur majeur de la recherche, au service des citoyens, de l'économie et de l'Etat.


Il apporte des solutions concrètes à leurs besoins dans quatre domaines principaux : transition énergétique, transition numérique, technologies pour la médecine du futur, défense et sécurité sur un socle de recherche fondamentale. Le CEA s'engage depuis plus de 75 ans au service de la souveraineté scientifique, technologique et industrielle de la France et de l'Europe pour un présent et un avenir mieux maîtrisés et plus sûrs.


Implanté au coeur des territoires équipés de très grandes infrastructures de recherche, le CEA dispose d'un large éventail de partenaires académiques et industriels en France, en Europe et à l'international.


Les 20 000 collaboratrices et collaborateurs du CEA partagent trois valeurs fondamentales :


- La conscience des responsabilités

- La coopération

- La curiosité

As an intern at the CEA, you will have the opportunity to work within a world-renowned research environment. Our teams consist of passionate and dedicated experts, providing an ideal setting for learning and collaboration. You will have access to state-of-the-art equipment and top-tier research resources to carry out your assignments. The work conducted may potentially lead to a scientific publication.

Context :

Complex technical documents combine heterogeneous information such as text, tables, diagrams, figures and equations, often distributed across multiple pages. They include technical manuals, maintenance procedures, user guides, datasheets, product specifications, engineering documents, and technical or scientific reports.

Understanding such documents raises several challenges: retrieving relevant information across long documents, jointly interpreting heterogeneous modalities, linking information distributed over multiple pages, and performing multi-step reasoning.

This internship aims to develop multimodal agentic AI capable of planning and orchestrating specialized models and tools for complex document understanding and reasoning.

What do we expect from you?

To address these challenges, the internship will investigate the following research directions:

• Review existing benchmarks and, if necessary, develop a benchmark covering a fine-grained taxonomy of technical documents and multimodal reasoning tasks.
• Evaluate recent Vision-Language Models (VLMs) for technical document understanding.
• Design an agentic architecture able to decompose complex queries and plan multi-step reasoning.
• Dynamically retrieve relevant pages and select appropriate tools or models.
• Combine and reason over information from text, tables, figures, diagrams and equations across multiple pages.
• Evaluate the proposed approach against direct VLM and multimodal RAG baselines.
