NettetConsidering the temporal and nonlinear characteristics of canyon wind speed data, a hybrid transfer learning model based on a convolutional neural network (CNN) and gated recurrent neural network (GRU) is proposed to predict short-term canyon wind speed with fewer observation data. In this method, the time sliding window is used to extract time ... NettetTo tackle that task, we trained and adapted ResNet, a neu- ral network that has been shown to be particularly efficient with multivariate times series recording, on data acquired in a group of 16 participants. The aim of the model is to correctly classify short time windows of the signal as containing or not motor preparation.
