For more details, please check the pre-trained model weight repository. - https://huggingface.co/sentence-transformers/all-MiniLM-L6-v2 - Commit Hash: [7dbbc90392e2f80f3d3c277d6e90027e55de9125](https://huggingface.co/sentence-transformers/all-MiniLM-L6-v2/tree/7dbbc90392e2f80f3d3c277d6e90027e55de9125) ### Fine-tuning - Fine-tune the model using a contrastive objective. - Compute the cosine similarity from each possible sentence pairs from the batch. - Then apply the cross entropy loss by comparing with true pairs. #### Hyper parameters - Train the model during 100k steps using a batch size of 1024 (128 per TPU core). - Use a learning rate warm up of 500. - The sequence length was limited to 128 tokens. - Used the AdamW optimizer with a 2e-5 learning rate. - The full training script is accessible in this current repository: `train_script.py`. #### Datasets | Dataset | Paper | Number of training tuples | |--------------------------------------------------------|:----------------------------------------:|:--------------------------:| | [Reddit comments (2015-2018)](https://github.com/PolyAI-LDN/conversational-datasets/tree/master/reddit) | [paper](https://arxiv.org/abs/1904.06472) | 726,484,430 | | [S2ORC](https://github.com/allenai/s2orc) Citation pairs (Abstracts) | [paper](https://aclanthology.org/2020.acl-main.447/) | 116,288,806 | | [WikiAnswers](https://github.com/afader/oqa#wikianswers-corpus) Duplicate question pairs | [paper](https://doi.org/10.1145/2623330.2623677) | 77,427,422 | | [PAQ](https://github.com/facebookresearch/PAQ) (Question, Answer) pairs | [paper](https://arxiv.org/abs/2102.07033) | 64,371,441 | | [S2ORC](https://github.com/allenai/s2orc) Citation pairs (Titles) | [paper](https://aclanthology.org/2020.acl-main.447/) | 52,603,982 | | [S2ORC](https://github.com/allenai/s2orc) (Title, Abstract) | [paper](https://aclanthology.org/2020.acl-main.447/) | 41,769,185 | | [Stack Exchange](https://huggingface.co/datasets/flax-sentence-embeddings/stackexchange_xml) (Title, Body) pairs | -
