Applying Hierarchical Bayesian Neural Network in Failure Time Prediction

Table 3

Performance measures and their definitions.

Metrics	Calculation
RMSE	RMSE=∑^30𝑖=1(𝑇𝑖−𝑃𝑖)^2/30
MAD	MAD=∑^30𝑖=1|𝑇𝑖−𝑃𝑖|/30
MAPE	MAPE=∑^30𝑖=1|(𝑇𝑖−𝑃𝑖)/𝑇𝑖|/30
RMSPE	RMSPE=∑^30𝑖=1((𝑇𝑖−𝑃𝑖)/𝑇𝑖)^2/30

^∗Note that 𝑇 and 𝑃 represent the actual and predicted failure time, respectively.
