Client for the Polaris Hub.
Project description
Polaris
So many stars in the sky, yet one is enough to guide you home.
Polaris establishes a novel, industry‑certified standard to foster the development of impactful methods in AI-based drug discovery.
This library is a Python client to interact with the Polaris Hub. It allows you to:
- Download Polaris datasets and benchmarks.
- Evaluate a custom method against a Polaris benchmark.
- Create and upload new datasets and benchmarks.
[!WARNING] The Polaris Hub is currently released as a closed, private beta. We hope to officially release it early 2024.
Quick API Tour
import polaris as po
# Load the benchmark from the Hub
benchmark = po.load_benchmark("polaris/hello-world-benchmark")
# Get the train and test data-loaders
train, test = benchmark.get_train_test_split()
# Use the training data to train your model
# Get the input as an array with 'train.inputs' and 'train.targets'
# Or simply iterate over the train object.
for x, y in train:
...
# Work your magic to accurately predict the test set
predictions = [0.0 for x in test]
# Evaluate your predictions
results = benchmark.evaluate(predictions)
# Submit your results
results.upload_to_hub(owner="dummy-user")
Documentation
Please refer to the documentation, which contains tutorials for getting started with polaris and detailed descriptions of the functions provided.
