The paper introduces an innovative approach to improve the Transformer architecture’s ability to effectively represent temporal sequences, particularly when using longer lookback windows. By combining Pyramid RNN embeddings (PRE) with the Transformer’s capability to model multivariate dependencies, the authors create a new model called PRformer. PRE uses pyramidal one-dimensional convolutional layers to construct multiscale convolutional features that preserve temporal order, while RNNs layered atop these features learn multiscale time series representations sensitive to sequence order. This integration results in significant performance enhancements on various real-world datasets.
Low GrooveSquid.com (original content) Low Difficulty Summary
This approach can be used for time series prediction tasks and is particularly useful when using longer lookback windows. The authors demonstrate the effectiveness of their method by achieving state-of-the-art performance on several real-world datasets.
