Transfer Learning (TL) [1, 2] refers to methods for transferring knowledge learned in one setting (the source domain) to another setting (the target domain) and it is needed in the field of machine diagnostics and prognostics. The current industrial approach for developing machine diagnostic and prognostic methods usually relies on data acquired in experiments under controlled conditions prior to deployment of the equipment. Detecting or predicting failures and estimating machine health in this paradigm assumes that future field data will have a very similar distribution to the experiment data. However, many machines were operated under dynamic environmental conditions and were operated in a variety of ways. This makes the assumption that pre-deployment data and post-deployment data follow very similar distributions are unlikely to hold. Moreover, since industrial systems are not allowed to run until failure (for safety reasons), collecting data that has comprehensive coverage on various usages patterns and deterioration patterns is very challenging.
Therefore, machine diagnostic and prognostic methods needed: (i) adapting to more complex scenarios where unseen degradation patterns and new operating conditions are present (in the testing data); (ii) learning to utilize and transfer knowledge gained from operations of similar equipment/assets. A very popular approach for solving these two problems is Feature-Representation based TL. The feature-representation based TL, e.g. domain adaptation, aims at discovering meaningful common structures between the source and the target domain, finding transformations that project the source data and the target data into a common latent feature space, which has predictive qualities for solving the target task. At the same time is the difference in the marginal distribution between the source and the target domain in the latent feature space reduced. Recently, Domain Adversarial Neural Networks (DANN) [3-8] have emerged for performing domain adaptation. The main objective of this work is to develop DANN based models to perform machine diagnostics and prognostics, propose cost functions and design NN structure. The proposed methods will be tested using both simulated data and real data coming from heaving duty vehicles.
