CHEME AI Lab

Chemical Engineering & Medical Imaging AI Lab

Integrating fundamental applied science understanding into technology has been a continuous process throughout history, and the CHEME AI Lab works to make today’s data-driven artificial intelligence (AI) stronger. We investigate knowledge-driven AI and demonstrate its potential within two applied science domains in particular – chemical engineering and imaging physics. Our research also applies to a wider range of applications. It explores fundamental ways to instil knowledge into all key components of AI: data acquisition, algorithm design, user interaction and deployment. Such knowledge-driven AI aims to be more interpretable and reliable than purely data-driven AI, and it will further drive future scientific development in chemical engineering and imaging physics.

The CHEME AI Lab is part of the TU Delft AI Labs programme.

Qian Tao one of the promising research projects on AI starting within NGF AiNed XS Europa

With these subsidies from the National Growth Fund programme AiNed promising ideas and innovative and speculative initiatives in the AI domain can be explored. As one out of ten, Qian Tao (AS) received a grant with her project on ‘physics-informed generative medical imaging: an AI-for-AI solution to fair data. Her project will lead to a proof-of-concept MI data curation method that is fair, cost-effective, and privacy-compliant. It potentially transforms medical imaging AI, towards significantly reduced financial and regulatory costs and enhanced fairness.

NWO Open Science Fund

Artur Schweidtmann (AS) has won a NWO Open Science Fund with his proposal for an open-source knowledge graph database for chemical engineering. His project is one of the 26 projects that were honoured by this call for the first time this year (and the only one from TU Delft). The ‘ChemEng KG’ aims to accelerate process development in academia and industry. Flowsheet simulations are crucial for (bio-)chemical process development. However, no public database for flowsheet simulation files exists, which is a major hurdle as knowledge from earlier simulations is not easily findable, accessible, interoperable, and reusable. “We envision establishing an open-source knowledge graph database for flowsheet simulation data that is FAIR and linked to leading initiatives in the open science community. The ‘ChemEng KG’ will accelerate process development in academia and industry. In addition, it will pave the way for automated process design through optimisation and machine learning."
