Smarter fish farms could cut electricity use and CO₂ while keeping fish safe

Saitama University
Peer-Reviewed Publication

A joint research team from Saitama University and the University of the Ryukyus has developed an energy management framework for recirculating aquaculture systems that coordinates renewable energy, battery storage, and aerator operation while maintaining dissolved oxygen levels needed to keep fish safe. By combining experimental data from Malabar grouper with model predictive control, the framework reduced annual electricity use by 17.8% and CO₂ emissions by 31.9% in simulations, while also helping maintain dissolved oxygen levels during power outages.

New W² metric could improve how AI prediction models are evaluated in environmental health

Shenyang Agricultural University Collaborative Journals
Peer-Reviewed Publication

Artificial intelligence is increasingly used to estimate pollutant concentrations, human exposure, and disease risks. However, researchers warn that commonly reported performance measures may give an incomplete picture of whether these predictions are truly reliable.

KAIST develops AI that avoids hallucinating even at night or in smoke

The Korea Advanced Institute of Science and Technology (KAIST)
Reports and Proceedings

- A research team led by Professor Yong Man Ro from the School of Electrical Engineering addressed AI hallucinations caused by sensory misinterpretation.

- Successfully suppressed cross-modal hallucination, in which the AI fabricates sounds that do not actually exist based on visual cues.

- The technology can be applied without additional model training, paving the way for next-generation autonomous vehicles, robots, drones, and security screening systems.
