+ # Model Card for `passage-ranker.chocolate`
7
+
8
+ This model is a passage ranker developed by Sinequa. It produces a relevance score given a query-passage pair and is
9
+ used to order search results.
10
+
11
+ Model name: `passage-ranker.chocolate`
12
+
13
+ ## Supported Languages
14
+
15
+ The model was trained and tested in the following languages:
16
+
17
+ - English
18
+
19
+ ## Scores
20
+
21
+ | Metric | Value |
22
+ |:--------------------|------:|
23
+ | Relevance (NDCG@10) | 0.484 |
24
+
25
+ Note that the relevance score is computed as an average over 14 retrieval datasets (see
26
+ [details below](#evaluation-metrics)).
27
+
28
+ ## Inference Times
29
+
30
+ | GPU | Batch size 32 |
31
+ |:-----------|--------------:|
32
+ | NVIDIA A10 | 22 ms |
33
+ | NVIDIA T4 | 64 ms |
34
+
35
+ The inference times only measure the time the model takes to process a single batch, it does not include pre- or
36
+ post-processing steps like the tokenization.
37
+
38
+ ## Requirements
39
+
40
+ - Minimal Sinequa version: 11.10.0
41
+ - GPU memory usage: 550 MiB
42
+
43
+ Note that GPU memory usage only includes how much GPU memory the actual model consumes on an NVIDIA T4 GPU with a batch
44
+ size of 32. It does not include the fix amount of memory that is consumed by the ONNX Runtime upon initialization which
45
+ can be around 0.5 to 1 GiB depending on the used GPU.
46
+
47
+ ## Model Details
48
+
49
+ ### Overview
50
+
51
+ - Number of parameters: 23 million
52
+ - Base language model: [MiniLM-L6-H384-uncased](https://huggingface.co/nreimers/MiniLM-L6-H384-uncased)
53
+ ([Paper](https://arxiv.org/abs/2002.10957), [GitHub](https://github.com/microsoft/unilm/tree/master/minilm))
54
+ - Insensitive to casing and accents
55
+ - Training procedure: [MonoBERT](https://arxiv.org/abs/1901.04085)
56
+
57
+ ### Training Data
58
+
59
+ - MS MARCO Passage Ranking
60
+ ([Paper](https://arxiv.org/abs/1611.09268),
61
+ [Official Page](https://microsoft.github.io/msmarco/),
62
+ [dataset on HF hub](https://huggingface.co/datasets/unicamp-dl/mmarco))
63
+
64
+ ### Evaluation Metrics
65
+
66
+ To determine the relevance score, we averaged the results that we obtained when evaluating on the datasets of the
67
+ [BEIR benchmark](https://github.com/beir-cellar/beir). Note that all these datasets are in English.
