WebSep 20, 2024 · Feature embedding is stored in the file feature_embeddings.pth. Just wondering if any one can help to visualise the features using TSNE. You could load the data via torch.load, transform it to a numpy array via arr = tensor.numpy (), and use e.g. sklearn.manifold.TSNE to visualize it. Thanks so much, Ptrblck for the help. WebJudging by the documentation of sklearn, TSNE simply does not have any transform method. Also, TSNE is an unsupervised method for dimesionality reduction/visualization, so it does not really work with a TRAIN and TEST. You simply take all of your data and use fit_transform to have the transformation and plot it. ios swift device console log
