This is a
sentence-transformers model: It maps sentences & paragraphs to a 768 dimensional dense vector space and can be used for tasks like clustering or semantic search.
Using this model becomes easy when you have
sentence-transformers installed:
1from sentence_transformers import SentenceTransformer
2sentences = ["أنا أحب القراءة والكتابة.", "الطيور تحلق في السماء."]
3
4model = SentenceTransformer('FDSRashid/QulBERT')
5embeddings = model.encode(sentences)
6print(embeddings)
Without
sentence-transformers, you can use the model like this: First, you pass your input through the transformer model, then you have to apply the right pooling-operation on-top of the contextualized word embeddings.

6def mean_pooling(model_output, attention_mask):
7 token_embeddings = model_output[0] #First element of model_output contains all token embeddings
8 input_mask_expanded = attention_mask.unsqueeze(-1).expand(token_embeddings.size()).float()
9 return torch.sum(token_embeddings * input_mask_expanded, 1) / torch.clamp(input_mask_expanded.sum(1), min=1e-9)
