+# sentence-BERTino
+
+This is a [sentence-transformers](https://www.SBERT.net) model: It maps sentences & paragraphs to a 768 dimensional dense vector space and can be used for tasks like clustering or semantic search. It was trained on 1M examples from [mmarco](https://huggingface.co/datasets/unicamp-dl/mmarco/viewer/italian/train). 
+
+## Usage (Sentence-Transformers)
+
+Using this model becomes easy when you have [sentence-transformers](https://www.SBERT.net) installed:
+```
+pip install -U sentence-transformers
+```
+Then you can use the model like this:
+```python
+from sentence_transformers import SentenceTransformer
+sentences = ["Questo è un esempio di frase", "Questo è un ulteriore esempio"]
+
+model = SentenceTransformer('efederici/mmarco-sentence-BERTino')
+embeddings = model.encode(sentences)
+print(embeddings)
+```
+## Usage (HuggingFace Transformers)
+
+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.
+```python
+from transformers import AutoTokenizer, AutoModel
+import torch
+
+
+#Mean Pooling - Take attention mask into account for correct averaging
+def mean_pooling(model_output, attention_mask):
+    token_embeddings = model_output[0] #First element of model_output contains all token embeddings
+    input_mask_expanded = attention_mask.unsqueeze(-1).expand(token_embeddings.size()).float()
+    return torch.sum(token_embeddings * input_mask_expanded, 1) / torch.clamp(input_mask_expanded.sum(1), min=1e-9)
+
+# Sentences we want sentence embeddings for
+sentences = ["Questo è un esempio di frase", "Questo è un ulteriore esempio"]
+
+# Load model from HuggingFace Hub
+tokenizer = AutoTokenizer.from_pretrained('efederici/mmarco-sentence-BERTino')
+model = AutoModel.from_pretrained('efederici/mmarco-sentence-BERTino')
+
+# Tokenize sentences
+encoded_input = tokenizer(sentences, padding=True, truncation=True, return_tensors='pt')
+
+# Compute token embeddings
+with torch.no_grad():
+    model_output = model(**encoded_input)
+# Perform pooling. In this case, mean pooling.
+sentence_embeddings = mean_pooling(model_output, encoded_input['attention_mask'])
+print("Sentence embeddings:")
+print(sentence_embeddings)
+```
