How to Edit My Own GAMs?

You can use this demo to edit your own GAMs: choose the my model tab and upload the model.json (model weights) and sample.json (sample data to evaluate the model).

If you use EBM, you can generate these two files easily with the GAM Changer python package.

# First install the GAM Changer python package
pip install gamchanger

import gamchanger as gc
from json import dump

# Extract model weights
model_data = gc.get_model_data(ebm)

# Generate sample data
sample_data = gc.get_sample_data(ebm, x_test, y_test)

# Save to `model.json` and `sample.json`
dump(model_data, open('./model.json', 'w'))
dump(sample_data, open('./sample.json', 'w'))

Computational Notebook Widget

You can use GAM Changer directly in your computational notebooks (e.g., Jupyter Notebook, VSCode Notebook, Google Colab).

Check out three live notebook demos below.

Jupyter Lite	Binder	Google Colab

Use the following snippet to load GAM Changer in your favorite notebooks:

# Install the GAM Changer python package
!pip install gamchanger

import gamchanger as gc

# Load GAM Changer with the model and sample data
gc.visualize(ebm, x_feed, y_feed)

Load Edited Models

After finishing editing a model, you can save the new model along with all the editing history to a *.gamchanger file by clicking the save button. You can load the new model in Python:

from json import load
import gamchanger as gc

# Load the `*.gamchanger` file
gc_dict = load(open('./edit-8-27-2021.gamchanger', 'r'))

# This will return a deep copy of your original EBM where edits are applied
new_ebm = gc.get_edited_model(ebm, gc_dict)

Development

Clone or download this repository:

git clone [e-mail]:interpretml/gam-changer.git

# use degit if you don't want to download commit histories
degit interpretml/gam-changer.git

Install the dependencies:

npm install

Then run GAM Changer:

npm run dev

Navigate to localhost:5000. You should see GAM Changer running in your browser :)
