Abstract

This paper proposes a missing data imputation method based on CGAN, enhanced with spectral normalization. To evaluate the effectiveness of the proposed method, two approaches are developed: a fault diagnosis model based on LSTM and CNN, and an FID score algorithm based on LSTM. These approaches transform the imputation results into more intuitive and measurable forms. Experimental results on the TE dataset demonstrate the strong performance of the proposed approach.
