Attention-based RNN modeling technique could be potentially used for investigating a variety of process engineering problems that require multiple step predictions. This type of model consists of an RNN that encodes a sequence of time series data into a new representation form, an another RNN that decodes the representation into a target sequence, as well as an attention model added in between that allows the model to focus on part of the input sequence that are critical to predicting the target sequence. The model with this deep architecture for high-level representations can learn very complex dynamic systems. To demonstrate the effectiveness of the modeling approach, a comparative study on the problem of catalyst activity prediction is illustrated. (C) 2020 Published by Elsevier Ltd.
