WebApr 9, 2024 · Firstly, we convert one-dimensional data to a Gramian Angular Field (GAF) image showing a spatial correlation, and add three kinds of noise to the original GAF image to prevent overfitting. Secondly, we propose an Inception-Resnet-V2 model based on the attention mechanism ECANet, which can improve the training effect obviously. WebThe type of image we have chosen is Gramian Angular Summation/Difference Field (GASF/GADF). Such images had been proposed in the field of time series classification , where the authors evaluated the efficacy of representing time series in a polar coordinate system instead of the typical Cartesian coordinates. For a deep understanding of the ...
