Dropout Deep Belief Network Based Chinese Ancient Ceramic Non-Destructive Identification

Abstract

A non-destructive identification method was developed here based on dropout deep belief network in multi-spectral data of ancient ceramic. A fractional differential algorithm was proposed to enhance the spectral details by making use of the difference between the first and second-order differential pre-process spectral data. An unsupervised multi-layer restricted Boltzmann machine (RBM) was employed to extract some high-level features during pre-training. Some weight and bias values trained by RBM were used to initialize a back propagation (BP) neural network. The RBM deep belief network was fine-tuned by the BP neural network to promote the initiative performance of network training, which helped to overcome local optimal limitation of the network due to the random initializing weight parameter. The dropout strategy has been put forward into the RBM network to solve the over-fitting of small sample spectral data. The experimental results show that the proposed method has excellent recognition performance of the ceramics by comparisons with some other ones.

“…This method of selecting process parameters for the process of imitating ancient ceramics provides a new and effective idea. Huang and Guan [ 13 ] used an expert system to appraise blue and white porcelain in the Ming and Qing Dynasties. This research method has entered the scope of modern appraisal thinking.…”
