# Introduction

Updates that may improve an AI system’s accuracy can also introduce new
and unanticipated errors that damage user trust. Updates that introduce
new errors can also break trust between software components and machine
learning models, as these errors are propagated and compounded
throughout larger integrated AI systems. The Backward Compatibility ML
library is an open-source project for evaluating AI system updates in a
new way for increasing system reliability and human trust in AI
predictions for actions.

The Backward Compatibility ML project has two components:

- **A series of loss functions** in which users can vary the weight
  assigned to the dissonance factor and explore performance/capability
  tradeoffs during machine learning optimization.

- **Visualization widgets** that help users examine metrics and error
  data in detail. They provide a view of error intersections between
  models and incompatibility distribution across classes.

# Getting Started

1. Setup a Python virtual environment or Conda environment and activate it.
2. From within the root folder of this project do `pip install -r requirements.txt`
3. From within the root folder do `npm install`
4. From within the root folder of this project do `npm run build && pip install -e .` or `NODE_ENV=production npx webpack && pip install -e .`
5. You should now be able to import the `backwardcompatibilityml` module and use it.

# Examples

Start your Jupyter Notebooks server and load in the example notebook under the `examples` folder
to see how the `backwardcompatibilityml` module is used.

To demo the compatbility analysis widget, open the notebook `compatibility-analysis.ipynb` inside the examples folder. Below is a list other sample notebooks that may be of interest. For the full list of example notebooks, please refer to [Running the Backward Compatibility ML library examples](https://backwardcompatibilityml.readthedocs.io/en/latest/backwardcompatibilityml/topics/getting_started.html#running-the-backward-compatibility-ml-library-examples)

| Notebook name                                      | Framework  | Notes                            |
|----------------------------------------------------|------------|----------------------------------|
| compatibility-analysis-cifar10-resnet18-pretrained | PyTorch    | Uses a pre-trained model         |
| model-comparison-MNIST                             | PyTorch    | Uses ModelComparison widget      |
| tensorflow-new-error-cross-entropy-loss            | TensorFlow | General TensorFlow usage example |
| tensorflow-MNIST                                   | TensorFlow | Uses CompatibilityModel class    |

# MLflow
Compatibility sweeps are automatically logged with [MLflow](https://mlflow.org/). MLflow runs are logged in a folder named `mlruns` in the same directory as the notebook.
To view the MLflow dashboard, start the MLflow server by running `mlflow server --port 5200 --backend-store-uri ./mlruns`. Then, open the MLflow UI
in your browser by navigating to `localhost:5200`.

# Tests

To run tests, make sure that you are in the project root folder and do:

1. `pip install -r dev-requirements.txt`
2. `pytest tests/`
3. `npm install`
4. `npm run test`

# Development Environment

This is provided as a convenience tool to developers, in order to allow development of the widget proceed outside of a Jupyter notebook environment.

The widget can be loaded in the web browser at `localhost:3000` or `<your-ip>:3000`. It will be loaded independently from a Jupyter notebook. The APIs will be hosted at `localhost:5000` or `<your-ip>:5000`.

Changes to the CSS or TypeScript code will be hot loaded automatically in the browser. Flask will run in debug mode and automatically restart whenever the Python code is changed.

## Compatibility Analysis Widget

- Open a new terminal and within the project root folder do `FLASK_ENV=development FLASK_APP=development/compatibility-analysis/app.py flask run --host 0.0.0.0 --port 5000` on Linux or `set FLASK_ENV=development && set FLASK_APP=development\compatibility-analysis\app.py && flask run --host 0.0.0.0 --port 5000` on Windows. This will start the Flask server for the APIs used by the widget.
- Open a new terminal, then from within the project root folder do `npm run start-compatibility-analysis`
- Open your browser and point it to `http://<your-ip-address>:3000`

## Model Comparison Widget

- Open a new terminal and within the project root folder do `FLASK_ENV=development FLASK_APP=development/model-comparison/app.py flask run --host 0.0.0.0 --port 5000` on Linux or `set FLASK_ENV=development && set FLASK_APP=development\model-comparison\app.py && flask run --host 0.0.0.0 --port 5000` on Windows. This will start the Flask server for the APIs used by the widget.
- Open a new terminal, then from within the project root folder do `npm run start-model-comparison`.
- Open your browser and point it to `http://<your-ip-address>:3000`
