PoF participated in the 2026 KSPHM-KIMM Machine Data Challenge and was awarded the Encouragement Award (장려상) for finishing 7th place out of 80 teams and 259 participants. This challenge was a competition to verify the performance and applicability of AI-based prognosis on actual bearing degradation data provided by Korea Institute of Machinery & Materials (KIMM). Through this experience PoF members acquired experience in developing AI-based prognosis algorithms based on real machinery signal data. Deeper research and understanding of AI-based prognosis will be studied further within the lab. 

🔗This achievement was also featured in the KIMM News.
