| # Training Data for Text Embedding Models | |
| This repository contains training files to train text embedding models, e.g. using [sentence-transformers](https://www.SBERT.net). | |
| ## Data Format | |
| All files are in a `jsonl.gz` format: Each line contains a JSON-object that represent one training example. | |
| The JSON objects can come in different formats: | |
| - **Pairs:** `["text1", "text2"]` - This is a positive pair that should be close in vector space. | |
| - **Triplets:** `["anchor", "positive", "negative"]` - This is a triplet: The `positive` text should be close to the `anchor`, while the `negative` text should be distant to the `anchor`. | |
| ## Available Datasets | |
| **Note: I'm currently in the process to upload the files. Please check again next week to get the full list of datasets** | |
| We measure the performance for each training dataset by training the [nreimers/MiniLM-L6-H384-uncased](https://huggingface.co/nreimers/MiniLM-L6-H384-uncased) model on it with [MultipleNegativesRankingLoss](https://www.sbert.net/docs/package_reference/losses.html#multiplenegativesrankingloss), a batch size of 256, for 2000 training steps. The performance is then averaged across 14 sentence embedding benchmark datasets from diverse domains (Reddit, Twitter, News, Publications, E-Mails, ...). | |
