Overview

• Team ZJUKLAB tackled model unlearning at SemEval-2025 Task 4
• Developed an innovative model merging approach for efficient unlearning
• Combined a base model with a model fine-tuned on retain data
• Used weight interpolation with task-specific parameter selection
• Achieved competitive performance while maintaining utility
• Demonstrated better unlearning efficiency than gradient-based methods

Plain English Explanation

When we teach AI models, they learn everything we show them. But sometimes we need them to forget specific information - like private data or harmful content. This is called "machine unlearning."

Team ZJUKLAB created a clever way to make AI models forget certain things without...
