+ # SetFit with sentence-transformers/all-MiniLM-L6-v2
26
+
27
+ This is a [SetFit](https://github.com/huggingface/setfit) model that can be used for Text Classification. This SetFit model uses [sentence-transformers/all-MiniLM-L6-v2](https://huggingface.co/sentence-transformers/all-MiniLM-L6-v2) as the Sentence Transformer embedding model. A [LogisticRegression](https://scikit-learn.org/stable/modules/generated/sklearn.linear_model.LogisticRegression.html) instance is used for classification.
28
+
29
+ The model has been trained using an efficient few-shot learning technique that involves:
30
+
31
+ 1. Fine-tuning a [Sentence Transformer](https://www.sbert.net) with contrastive learning.
32
+ 2. Training a classification head with features from the fine-tuned Sentence Transformer.

36
+ # all-MiniLM-L6-v2
37
+ This is a [sentence-transformers](https://www.SBERT.net) model: It maps sentences & paragraphs to a 384 dimensional dense vector space and can be used for tasks like clustering or semantic search.
38
+
39
+ ## Usage (Sentence-Transformers)
40
+ Using this model becomes easy when you have [sentence-transformers](https://www.SBERT.net) installed:
41
+
42
+ ```
43
+ pip install -U sentence-transformers
44
+ ```
45
+
46
+ Then you can use the model like this:
47
+ ```python
48
+ from sentence_transformers import SentenceTransformer
49
+ sentences = ["This is an example sentence", "Each sentence is converted"]
50
+
51
+ model = SentenceTransformer('sentence-transformers/all-MiniLM-L6-v2')
52
+ embeddings = model.encode(sentences)
53
+ print(embeddings)
54
+ ```
55
+
56
+ ## Usage (HuggingFace Transformers)
57
+ 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.
58
+
59
+ ```python
60
+ from transformers import AutoTokenizer, AutoModel
61
+ import torch
62
+ import torch.nn.functional as F
63
+
64
+ #Mean Pooling - Take attention mask into account for correct averaging
65
+ def mean_pooling(model_output, attention_mask):
66
+ token_embeddings = model_output[0] #First element of model_output contains all token embeddings
67
+ input_mask_expanded = attention_mask.unsqueeze(-1).expand(token_embeddings.size()).float()
68
+ return torch.sum(token_embeddings * input_mask_expanded, 1) / torch.clamp(input_mask_expanded.sum(1), min=1e-9)
69
+
70
+
71
+ # Sentences we want sentence embeddings for
72
+ sentences = ['This is an example sentence', 'Each sentence is converted']
73
+
74
+ # Load model from HuggingFace Hub
75
+ tokenizer = AutoTokenizer.from_pretrained('sentence-transformers/all-MiniLM-L6-v2')
76
+ model = AutoModel.from_pretrained('sentence-transformers/all-MiniLM-L6-v2')
77
+
78
+ # Tokenize sentences
79
+ encoded_input = tokenizer(sentences, padding=True, truncation=True, return_tensors='pt')
80
+
81
+ # Compute token embeddings
82
+ with torch.no_grad():
83
+ model_output = model(**encoded_input)
84
+
85
+ # Perform pooling
86
+ sentence_embeddings = mean_pooling(model_output, encoded_input['attention_mask'])
87
+
88
+ # Normalize embeddings
89
+ sentence_embeddings = F.normalize(sentence_embeddings, p=2, dim=1)
90
+
91
+ print("Sentence embeddings:")
92
+ print(sentence_embeddings)
93
+ ```
94
+
95

96
+
97
+ ## Background
98
+
99
+ The project aims to train sentence embedding models on very large sentence level datasets using a self-supervised
100
+ contrastive learning objective. We used the pretrained [`nreimers/MiniLM-L6-H384-uncased`](https://huggingface.co/nreimers/MiniLM-L6-H384-uncased) model and fine-tuned in on a
101
+ 1B sentence pairs dataset. We use a contrastive learning objective: given a sentence from the pair, the model should predict which out of a set of randomly sampled other sentences, was actually paired with it in our dataset.
102
+
103
+ We developed this model during the
104
+ [Community week using JAX/Flax for NLP & CV](https://discuss.huggingface.co/t/open-to-the-community-community-week-using-jax-flax-for-nlp-cv/7104),
105
+ organized by Hugging Face. We developed this model as part of the project:
106
+ [Train the Best Sentence Embedding Model Ever with 1B Training Pairs](https://discuss.huggingface.co/t/train-the-best-sentence-embedding-model-ever-with-1b-training-pairs/7354). We benefited from efficient hardware infrastructure to run the project: 7 TPUs v3-8, as well as intervention from Googles Flax, JAX, and Cloud team member about efficient deep learning frameworks.
107
+
108
+ ## Intended uses
109
+
110
+ Our model is intended to be used as a sentence and short paragraph encoder. Given an input text, it outputs a vector which captures
111
+ the semantic information. The sentence vector may be used for information retrieval, clustering or sentence similarity tasks.
112
+
113
+ By default, input text longer than 256 word pieces is truncated.
114
+
115
+
116
+ ## Training procedure
117
+
118
+ ### Pre-training
119
+
120
+ We use the pretrained [`nreimers/MiniLM-L6-H384-uncased`](https://huggingface.co/nreimers/MiniLM-L6-H384-uncased) model. Please refer to the model card for more detailed information about the pre-training procedure.
121
+
122
+ ### Fine-tuning
123
+
124
+ We fine-tune the model using a contrastive objective. Formally, we compute the cosine similarity from each possible sentence pairs from the batch.
125
+ We then apply the cross entropy loss by comparing with true pairs.
126
+
127
+ #### Hyper parameters
128
+
129
+ We trained our model on a TPU v3-8. We train the model during 100k steps using a batch size of 1024 (128 per TPU core).
130
+ We use a learning rate warm up of 500. The sequence length was limited to 128 tokens. We used the AdamW optimizer with
131
+ a 2e-5 learning rate. The full training script is accessible in this current repository: `train_script.py`.
132
+
133
+ #### Training data
134
+
135
+ We use the concatenation from multiple datasets to fine-tune our model. The total number of sentence pairs is above 1 billion sentences.
136
+ We sampled each dataset given a weighted probability which configuration is detailed in the `data_config.json` file.
