Usage

For usage instructions, refer to: https://github.com/Muennighoff/sgpt#symmetric-semantic-search

The model was trained with the command

CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 accelerate launch examples/training/nli/training_nli_v2.py --model_name bigscience/bloom-1b3 --freezenonbias --train_batch_size 128 --lr 32e-5 --pooling weightedmean --wandb --wandbwatchlog gradients --gradcache --chunksize 4

Evaluation Results

{'askubuntu': 57.44, 'cqadupstack': 14.18, 'twitterpara': 73.99, 'scidocs': 74.74, 'avg': 55.087500000000006}

Training

The model was trained with the parameters:

DataLoader:

sentence_transformers.datasets.NoDuplicatesDataLoader.NoDuplicatesDataLoader of length 4403 with parameters:

{'batch_size': 128}

The model uses BitFit, weighted-mean pooling & GradCache, for details see: https://arxiv.org/abs/2202.08904

Loss:

sentence_transformers.losses.MultipleNegativesRankingLoss.MNRLGradCache
