Core offering

The HUN-REN Rényi Institute of Mathematics is Hungary's flagship public mathematical research institute, conducting fundamental research across pure mathematics (algebra, combinatorics, geometry, number theory, probability, topology, logic) and applied artificial intelligence (deep learning, graph neural networks, automated theorem proving, healthcare analytics, archival document processing). It runs 15+ research departments, the Erdős Center, and educational programs including Budapest Semesters in Mathematics for international PhD-level students.

Product overview

HUN-REN Rényi Institute of Mathematics is a mathematical research institute, not a product company. Its primary outputs are research publications and AI applications developed by its Rényi AI Research Group. The Rényi AI group operates as an internal research & development team offering multiple AI capabilities: healthcare analytics (patient pathway modeling, disease prediction), archival document processing (Document Image Enhancement and semi-agentic RAG systems), neural network analysis tools (Dr. Frankenstein, Global Sinkhorn Autoencoder), automated theorem proving, and combinatorial optimization (Diverse Beam Search). These are research outputs rather than commercial products offered for sale. The institute also maintains institutional services including a library (with Corvina OPAC catalog and academic database access) and an internal AURA web portal for administrative operations.

• Semi-Agentic Archival RAG System Retrieval-Augmented Generation system for archival access combining high-quality transcriptions with original scanned images via hybrid search pipeline, featuring a conversational ChatGPT-like interface with precise citations back to original pages. Developed for the Council of Ministers' meeting minutes from the first Imre Nagy government.
• AI-Based Energy Information and Production Management System Real-time autonomous AI-based energy information and production management system for smart power plant optimization, integrating weather-dependent renewable energy sources and improving electricity system stability for ALTEO Energy Service Plc.
• Budapest Semesters in Mathematics (BSM) PhD-level mathematics education program providing semester-based training in advanced mathematics to international students, administered jointly with the Budapest University of Technology and Economics.
• Rényi Institute Library Institutional research library providing catalog access (OPAC via CorvinaWeb), access to major academic databases, and research support services, holding collected papers of Paul Erdős, Alfréd Rényi, and Vera T. Sós.
• Rényi AI Research Group The AI Research & Development division of the HUN-REN Rényi Institute of Mathematics, conducting both foundational mathematical AI research and applied machine learning projects for consortium partners in healthcare, government archives, and energy.
