For compared to all the rest, this has been the best chronicled, not only in Spanish, but also in Chinese sources. Since the stock data is a typical time series, we choose LSTM model, which is widely applied to time series prediction, as the generative model to predict output based on the input data ; that is,. We add a feature extractor specific for industrial time series which is able to present the unique feature of a period and at the same time reduce dimension and computing time before the data is feed into our fault detector. It is possible to predict when there is a given condition, but it may be difficult to 28 predict when a new input provided. There are many machine learning algorithms with some appropriate choice of features which deal with time series data.
