Model Card for vectorizer.vanilla
This model is a vectorizer developed by Sinequa. It produces an embedding vector given a passage or a query. The passage vectors are stored in our vector index and the query vector is used at query time to look up relevant passages in the index.
Model name: vectorizer.vanilla
Supported Languages
The model was trained and tested in the following languages:
- English
Scores
| Metric | Value |
|---|---|
| Relevance (Recall@100) | 0.639 |
Note that the relevance score is computed as an average over 14 retrieval datasets (see details below).
Inference Times
| GPU | Batch size 1 (at query time) | Batch size 32 (at indexing) |
|---|---|---|
| NVIDIA A10 | 2 ms | 19 ms |
| NVIDIA T4 | 4 ms | 53 ms |
The inference times only measure the time the model takes to process a single batch, it does not include pre- or post-processing steps like the tokenization.
Requirements
- Minimal Sinequa version: 11.10.0
- GPU memory usage: 330 MiB
Note that GPU memory usage only includes how much GPU memory the actual model consumes on an NVIDIA T4 GPU with a batch size of 32. It does not include the fix amount of memory that is consumed by the ONNX Runtime upon initialization which can be around 0.5 to 1 GiB depending on the used GPU.
Model Details
Overview
- Number of parameters: 23 million
- Base language model: English MiniLM-L6-H384
- Insensitive to casing and accents
- Output dimensions: 256 (reduced with an additional dense layer)
- Training procedure: Query-passage-negative triplets for datasets that have mined hard negative data, Query-passage pairs for the rest. Number of negatives is augmented with in-batch negative strategy.
Training Data
The model have been trained using all datasets that are cited in the all-MiniLM-L6-v2 model.
Evaluation Metrics
To determine the relevance score, we averaged the results that we obtained when evaluating on the datasets of the BEIR benchmark. Note that all these datasets are in English.
