Explicit Model for Chiller Fault Diagnosis Based on Multi-objective Regression with Different Weights

Based on the cross-entropy loss function and stochastic gradient descent algorithm, a weight regression fault diagnosis model was established for seven common faults in a chiller. The weighted regression model was slightly more complex than the pure linear regression model; however, the fault diagno...
