+ # paecter
16
+
17
+ This is a [sentence-transformers](https://www.SBERT.net) model: It can be used to generate 1024 dimensional dense vector for patent texts for downstream tasks like semantic search, prior art search, clustering, and patent landscaping.
18
+
19
+ <!--- Describe your model here -->
20
+
21
+ ## Usage (Sentence-Transformers)
22
+
23
+ Using this model becomes easy when you have [sentence-transformers](https://www.SBERT.net) installed:
24
+
25
+ ```
26
+ pip install -U sentence-transformers
27
+ ```
28
+
29
+ Then you can use the model like this:
30
+
31
+ ```python
32
+ from sentence_transformers import SentenceTransformer
33
+ sentences = ["This is an example sentence", "Each sentence is converted"]
34
+
35
+ model = SentenceTransformer('paecter')
36
+ embeddings = model.encode(sentences)
37
+ print(embeddings)
38
+ ```
39
+
40
+
41
+
42
+ ## Usage (HuggingFace Transformers)
43
+ Without [sentence-transformers](https://www.SBERT.net), 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.
44
+
45
+ ```python
46
+ from transformers import AutoTokenizer, AutoModel
47
+ import torch
48
+
49
+
50
+ #Mean Pooling - Take attention mask into account for correct averaging
51
+ def mean_pooling(model_output, attention_mask):
52
+ token_embeddings = model_output[0] #First element of model_output contains all token embeddings
53
+ input_mask_expanded = attention_mask.unsqueeze(-1).expand(token_embeddings.size()).float()
54
+ return torch.sum(token_embeddings * input_mask_expanded, 1) / torch.clamp(input_mask_expanded.sum(1), min=1e-9)
55
+
56
+
57
+ # Sentences we want sentence embeddings for
58
+ sentences = ['This is an example sentence', 'Each sentence is converted']
59
+
60
+ # Load model from HuggingFace Hub
61
+ tokenizer = AutoTokenizer.from_pretrained('paecter')
62
+ model = AutoModel.from_pretrained('paecter')
63
+
64
+ # Tokenize sentences
65
+ encoded_input = tokenizer(sentences, padding=True, truncation=True, return_tensors='pt')
66
+
67
+ # Compute token embeddings
68
+ with torch.no_grad():
69
+ model_output = model(**encoded_input)
70
+
71
+ # Perform pooling. In this case, mean pooling.
72
+ sentence_embeddings = mean_pooling(model_output, encoded_input['attention_mask'])
73
+
74
+ print("Sentence embeddings:")
75
+ print(sentence_embeddings)
76
+ ```
77
+

+ ## Evaluation Results
