-## Evaluation Results
-For an automated evaluation of this model, see the *Sentence Embeddings Benchmark*: [https://seb.sbert.net](https://seb.sbert.net?model_name=sentence-transformers/all-MiniLM-L6-v2)
-------
-## Background
-The project aims to train sentence embedding models on very large sentence level datasets using a self-supervised
-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
-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.
-We developed this model during the
-[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),
-organized by Hugging Face. We developed this model as part of the project:
-[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.
-## Intended uses
-Our model is intended to be used as a sentence and short paragraph encoder. Given an input text, it outputs a vector which captures
-the semantic information. The sentence vector may be used for information retrieval, clustering or sentence similarity tasks.
-By default, input text longer than 256 word pieces is truncated.
-## Training procedure
-### Pre-training
-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.
-### Fine-tuning
-We fine-tune the model using a contrastive objective. Formally, we compute the cosine similarity from each possible sentence pairs from the batch.
-We then apply the cross entropy loss by comparing with true pairs.
-#### Hyper parameters
-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).
-We use a learning rate warm up of 500. The sequence length was limited to 128 tokens. We used the AdamW optimizer with
-a 2e-5 learning rate. The full training script is accessible in this current repository: `train_script.py`.
-#### Training data
-We use the concatenation from multiple datasets to fine-tune our model. The total number of sentence pairs is above 1 billion sentences.
-We sampled each dataset given a weighted probability which configuration is detailed in the `data_config.json` file.

+# Dialog2Flow single target (DSE-base)
+This a variation of the **D2F$_{single}$** model introduced in the paper ["Dialog2Flow: Pre-training Soft-Contrastive Action-Driven Sentence Embeddings for Automatic Dialog Flow Extraction"](https://publications.idiap.ch/attachments/papers/2024/Burdisso_EMNLP2024_2024.pdf) published in the EMNLP 2024 main conference.
+This version uses DSE-base as the backbone model which yields to an increase in performance as compared to the vanilla version using BERT-base as the backbone (results reported in Appendix C).
+Implementation-wise, 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 search.

+sentences = ["your phone please", "okay may i have your telephone number please"]
+model = SentenceTransformer('sergioburdisso/dialog2flow-single-dse-base')
 embeddings = model.encode(sentences)
 print(embeddings)
 ```
 ## Usage (HuggingFace Transformers)

+tokenizer = AutoTokenizer.from_pretrained('sergioburdisso/dialog2flow-single-dse-base')

 # Tokenize sentences
 encoded_input = tokenizer(sentences, padding=True, truncation=True, return_tensors='pt')
 with torch.no_grad():
