چکیده
Mechanical fault prediction is one of the main problems in condition-based maintenance, and its purpose to predict future working status machine based on collected information machine. However, hand, model health indices by sensors will directly affect evaluation results system. On other because index a continuous time series, effect feature learning data also affects prognosis. This paper makes full use autonomous fusion capability stacked autoencoder strong deep belief networks for data, proposes novel prognosis method. Firstly, used construct through vibration signals sensors. To solve local fluctuations indices, exponentially weighted moving average method smooth reduce impact noise. Then, network perform constructed performance changes model. Finally, experiment bearing was performed. The experimental show that combines advantages autoencoders networks, has lower error than traditional intelligent methods.

Deep Dictionary Learning vs Deep Belief Network vs Stacked Autoencoder: An Empirical Analysis
A recent work introduced the concept of deep dictionary learning. The first level is a dictionary learning stage where the inputs are the training data and the outputs are the dictionary and learned coefficients. In subsequent levels of deep dictionary learning, the learned coefficients from the previous level acts as inputs. This is an unsupervised representation learning technique. In this wo...

متن کاملTransformer fault diagnosis using continuous sparse autoencoder.
This paper proposes a novel continuous sparse autoencoder (CSAE) which can be used in unsupervised feature learning. The CSAE adds Gaussian stochastic unit into activation function to extract features of nonlinear data. In this paper, CSAE is applied to solve the problem of transformer fault recognition. Firstly, based on dissolved gas analysis method, IEC three ratios are calculated by the con...
متن کاملRemote Sensing Image Classification Based on Stacked Denoising Autoencoder
Focused on the issue that conventional remote sensing image classification methods have run into the bottlenecks in accuracy, a new remote sensing image classification method inspired by deep learning is proposed, which is based on Stacked Denoising Autoencoder. First, the deep network model is built through the stacked layers of Denoising Autoencoder. Then, with noised input, the unsupervised ...
