Researchers use transfer learning to predict tonal noise in VRF units

Researchers have developed an unsupervised transfer learning method, Domain-invariant Partial Least Squares (Di-PLS), to predict tonal noise in VRF units. This approach utilizes thermodynamic and vibration signals to forecast noise levels under varying conditions. The study found that vibration signals provided more accurate predictions than thermodynamic signals, with prediction errors within 3 dB. AI
