# FLMR model card
|
| 15 |
+
|
| 16 |
+
FLMR is an open-source model for multimodal knowledge retrieval. It is a transformer-based model that uses a combination of text and image inputs to retrieve relevant documents from a large corpus.
|
| 17 |
+
|
| 18 |
+

## Uses
|
| 33 |
+
|
| 34 |
+
### Direct Use
|
| 35 |
+
|
| 36 |
+
This model can be used directly to retrieve documents from a large corpus using a combination of text and image input queries. The retrieval usage can be found in the [official implementation](https://github.com/LinWeizheDragon/FLMR).
|
| 37 |
+
|
| 38 |
+
### Downstream Use
|
| 39 |
+
|
| 40 |
+
<!-- This section is for the model use when fine-tuned for a task, or when plugged into a larger ecosystem/app -->
|
| 41 |
+
|
| 42 |
+
This model can be used combined with language models to create a retrieval-augmented language model. The use for Knowledge-based VQA can be found in [RAVQA](https://github.com/linweizhedragon/retrieval-augmented-visual-question-answering)
|
| 43 |
+
|
| 44 |
+
## How to Get Started with the Model
|
| 45 |
+
|
| 46 |
+
For details of training, indexing, and performing retrieval, please refer to [here](https://github.com/LinWeizheDragon/FLMR).
|
| 47 |
+
|
| 48 |
+
## Training datasets
|
| 49 |
+
The model is pre-trained on
|
| 50 |
+
1. Image to Text retrieval: WIT
|
| 51 |
+
3. Image & Question to Text retrieval: OKVQA
|
| 52 |
+
|
| 53 |
+
For details on the dataset split and conversion process, please refer to the paper [Fine-grained Late-interaction Multi-modal Retrieval for Retrieval Augmented Visual Question Answering](https://openreview.net/forum?id=IWWWulAX7g).

+
## Evaluation datasets
|
| 61 |
+
|
| 62 |
+
The model is evaluated on OKVQA, Infoseek, and FVQA.
