Predicting Unmeasured Region of the Efficiency Map of a Speed Reducer Using a Denoising Auto-Encoder

This paper presents a Remaining Useful Life (RUL) prediction method for a speed reducer based on denoising au- to-encoder (DAE). Constructing the efficiency map of the re- ducer is an important process for predicting the life span. However, due to the situational constraints that occur, un- measured intervals hinder the completion of the efficiency map. to solve this problem, we propose a method that can pre- dict and reconstruct an unmeasured interval effectively and reliably by using DAE. In addition, we examine the applicabil- ity of the proposed algorithm through experiments that assume various situations.
