Automated early process fault detection and prediction remains a challenging problem in industrial processes. Traditionally it has been done by multivariate statistical analysis of sensor readings and, more recently, with the help of machine learning methods. The quality of machine learning models strongly depends on feature engineering, that in turn heavily relies on expertise of the process engineers and model developers. With the recent advent of deep learning neural network methods and abundance of available sensor data, it became possible to develop advanced approaches to early fault detection and prediction that do not require feature engineering and provide more accurate and timely results.

In this paper we investigate a wide range of recurrent and convolutional architectures on the publicly available simulated Tennessee Eastman Process extended TEP dataset for the fault detection in chemical processes. We have selected the best architecture for the task and proposed a novel temporal CNN1D2D architecture that achieves overall better performance on the dataset than any referenced method. We have also proposed to use Generative Adversarial Network GAN to extend and enrich data used in training.
