NuggetIndex: Governed Atomic Retrieval for Maintainable RAG

Saber Zerhoudi, Michael Granitzer, Jelena Mitrovic

Retrieval-augmented generation (RAG) systems are frequently evaluated via fact-based metrics, yet standard implementations retrieve passages or static propositions. This unit misma…

AgentSim: A Platform for Verifiable Agent-Trace Simulation

Saber Zerhoudi, Michael Granitzer, Jelena Mitrovic

Training trustworthy agentic LLMs requires data that shows the grounded reasoning process, not just the final answer. Existing datasets fall short: question-answering data is outco…

IIRSim Studio: A Dashboard for User Simulation

Saber Zerhoudi, Adam Roegiest, Michael Granitzer

User simulation is a valuable methodology for evaluation in Information Retrieval (IR), enabling low-cost experimentation and counterfactual analysis. However, existing simulation…

Approximation of Functions: Optimal Sampling and Complexity

David Krieg, Mario Ullrich

We consider approximation or recovery of functions based on a finite number of function evaluations. This is a well-studied problem in optimal recovery, machine learning, and numer…

Subgroups of Cyclically Amalgamated Free Products

Martin Kreuzer, Anja Moldenhauer, Gerhard Rosenberger

Given a group which is the free product of two finitely generated groups and with amalgamation over a cyclic subgroup which is malnormal in
