■ Research Overview
Our research develops a hybrid method for the video analysis of dynamic brainstorming sessions. Since training deep learning (DL) models is resource-intensive, we adapt the output of pre-trained models using symbolic processing. This achieves effective situation recognition at a low computational cost.
We also research secret sharing and secure computation to counter the threat of quantum computers to current cryptography. By distributing data, we achieve information-theoretic security, which is fundamentally stronger. This allows computation on decentralized data, preventing data reconstruction even if parts are compromised and ensuring robustness against system failures.
Finally, we are developing double-oriented computing, a new paradigm that adds sustainability to the autonomy of agent-oriented systems. As system complexity now leads to large-scale failures, our work aims to ensure continuous service and resilience by creating mechanisms that can withstand partial system failures.
