Google has launched the first-ever Machine Unlearning Challenge aimed at improving the ability of AI to forget or remove specific training examples. As artificial intelligence (AI) advances and more sensitive information is processed, the need to responsibly and effectively manage the data these models learn from has become increasingly crucial.
In a bid to uphold Google’s AI principles, including the propagation and mitigation of unfair biases and safeguarding user privacy, the challenge encourages the development of machine unlearning mechanisms. The term "machine unlearning" refers to the ability of an AI to remove the influence of a specific subset of training examples (known as the "forget set") from a trained model.
Efficient unlearning is important not only to protect user privacy, but also to erase inaccurate or outdated information from trained models or remove harmful, manipulated, or outlier data. This initiative will potentially open ways to increase fairness in models by addressing unfair biases or disparate treatment of members belonging to different groups.
The challenge, which is part of the NeurIPS 2023 Competition Track, seeks to standardize evaluation metrics and provide a platform for competitors to develop innovative solutions. Hosted on Kaggle, the competition will run from mid-July 2023 to mid-September 2023, and a starting kit is now available to help participants get a head start.
The Machine Unlearning Challenge considers a realistic scenario where an age predictor has been trained on face images. Following training, a subset of the training images needs to be "forgotten" to protect the privacy of the individuals concerned.
Submissions will be evaluated on the strength of the forgetting algorithm and model utility, with a hard cut-off that rejects unlearning algorithms running slower than a fraction of the time it takes to retrain. The competition hopes to provide an understanding of the trade-offs of different unlearning algorithms.
