Announcing the first Machine Unlearning Challenge
Sub: Sci
Sec: Awareness in IT
Context:
- Google announced the first Machine Unlearning Challenge, which will be held as part of the NeurIPS 2023 Competition Track.
What is Machine Unlearning:
- Machine unlearning refers to the process of selectively removing specific training data points and their influence on an already trained model, making the updated model behave the same as a model that was never trained on that data.
- It provides a ‘subtractive’ capability to adapt models by removing unauthorized, malicious, or outdated data points without full retraining.
- Machine unlearning plays an important role in ML models.
- The field of machine unlearning is related to other areas of machine learning such as differential privacy, life-long learning, and fairness.
What are the challenges of machine unlearning?
- The problem of unlearning is complex and multifaceted as it involves several conflicting objectives like forgetting the requested data, maintaining the model’s utility (e.g., accuracy on retained and held-out data), and efficiency.
- Also the evaluation of forgetting algorithms in the literature has so far been highly inconsistent.
- Another challenge in this space is the effective erasure of data that has been requested to be deleted.
- The unlearning process itself can leak information in multiple ways.
- Tracing each data point’s influence becomes increasingly difficult as the dataset changes dynamically.
Unlearning challenge:
- Google announced the first Machine Unlearning Challenge, which will be held as part of the NeurIPS 2023 Competition Track.
- The goal of the competition is twofold.
- Unifying and standardizing the evaluation metrics for unlearning to identify the strengths and weaknesses of different algorithms through apples-to-apples comparisons.
- Opening this competition to everyone, will foster novel solutions and shed light on open challenges and opportunities.
- The competition was hosted on Kaggle and ran between mid-July 2023 and mid-September 2023.
