WebOct 1, 2024 · This is where the technique behind the word embedding will be useful. Word embedding is a technique commonly applied in Natural Language Processing to transform words into numeric values in the form of vectors. These vectors will occupy the embedding space with certain dimensions. WebEmbeddingBag also supports per-sample weights as an argument to the forward pass. This scales the output of the Embedding before performing a weighted reduction as specified by mode. If per_sample_weights is passed, the only supported mode is "sum", which computes a weighted sum according to per_sample_weights. Parameters: num_embeddings ( int ...
