RefusalBench: Why Refusal Rate Misranks Frontier LLMs on Biological Research Prompts
Lukas Weidener, Marko BrkiÄ, Mihailo JovanoviÄ +2
Frontier large language models are increasingly deployed as orchestration backbones for biological research workflows, yet no shared evidence base exists for comparing their refusa…
From oblique-wave forcing to streak reinforcement: A perturbation-based frequency-response framework
DuÅ¡an BožiÄ, Anubhav Dwivedi, Mihailo R. JovanoviÄ
We develop a perturbation-based frequency-response framework for analyzing amplification mechanisms that are central to subcritical routes to transition in wall-bounded shear flows…
Rethinking the AI Scientist: Interactive Multi-Agent Workflows for Scientific Discovery
Lukas Weidener, Marko BrkiÄ, Mihailo JovanoviÄ +5
Artificial intelligence systems for scientific discovery have demonstrated remarkable potential, yet existing approaches remain largely proprietary and operate in batch-processing…
Tannenbaum's gain-margin optimization meets Polyak's heavy-ball algorithm
Wuwei Wu, Jie Chen, Mihailo R. JovanoviÄ +1
This paper highlights an apparent, yet relatively unknown link between algorithm design in optimization theory and controller synthesis in robust control. Specifically, quadratic o…
From Task Executors to Research Partners: Evaluating AI Co-Pilots Through Workflow Integration in Biomedical Research
Lukas Weidener, Marko BrkiÄ, Chiara Bacci +7
Artificial intelligence systems are increasingly deployed in biomedical research. However, current evaluation frameworks may inadequately assess their effectiveness as research col…
Stability properties of gradient flow dynamics for the symmetric low-rank matrix factorization problem
Hesameddin Mohammadi, Mohammad Tinati, Stephen Tu +2
The symmetric low-rank matrix factorization serves as a building block in many learning tasks, including matrix recovery and training of neural networks. However, despite a flurry…
