LITMUS Predictor provides support for simulating performance in ~100 languages given training observations of the desired task-model. Each training observation specifies the finetuning-datasize + test-performance in different languages.

Further, the tool provides support for constructing a data-collection strategy to maximize performance in desired targets subject to different constraints.

## Installation
```
pip install -U pip
pip install -r requirements.txt
```

## Usage
`litmus/litmus_mixing.py` contains the implementation of the LITMUS Predictor which can be trained on observations of different task-model trainings.

## Examples

### From shell
```
python3 litmus_mixing.py xlmr --scores_file training_observations.json --common_scaling --error_method split --mode heatmap --data_sizes "en:1000,hi:1000;en:1000,ar:1000" --use_all_langs --heatmap_targets en,fr,de,hi,ar,ru
```

### From external scripts
```python
from litmus import litmus_mixing

data_file = "" # Location of train data file
args = litmus_mixing.parse_args([
    "xlmr", data_file,
    "--common_scaling",
    "--error_method", "kfold",
    "--training_algorithm", "xgboost"
])
res = litmus_mixing.litmus_main(args)
```

## WebApp
`frontend/` contains the code for hosting the tool as a webapp using Azure Functions. `frontend/WebUx` implements the client-side as a static website which interacts with a Azure Functions backend which internally runs the `litmus/litmus_mixing.py` script.

### Instructions to self-host

1. Create an Azure Functions resource on Azure.
2. Install [Azure CLI](https://docs.microsoft.com/en-us/cli/azure/) and [Functions Core Tools](https://docs.microsoft.com/en-us/azure/azure-functions/functions-run-local?tabs=linux%2Ccsharp%2Cportal%2Cbash%2Ckeda)
3. `cd` into the `frontend/` directory and deploy to azure functions using `func azure functionapp publish <function-resource-name>`.
