WebSep 6, 2024 · The variable to predict (often called the class or the label) is politics type, which has possible values of conservative, moderate or liberal. For PyTorch multi-class classification you must encode the variable to predict using ordinal encoding. The demo sets conservative = 0, moderate = 1 and liberal = 2. The order of the encoding is arbitrary. WebApr 14, 2024 · The torch.eq (tensor_one, tensor_two) function can help you in this situation.

WebApr 10, 2024 · The model performs pretty well in many cases, being able to search very similar images from the data pool. However in some cases, the model is unable to predict any labels and the embeddings of these images are almost identical, so the cosine similarity is 1.0. The search results thus become very misleading, as none of the images are similar.
