Changing the Training Data Distribution to Reduce Simplicity Bias Improves In-distribution Generalization
🤖AI Summary
Researchers developed USEFUL, a new training method that modifies data distribution to reduce simplicity bias in machine learning models. The approach clusters examples early in training and upsamples underrepresented data, achieving state-of-the-art performance when combined with optimization methods like SAM on popular image classification datasets.
Key Takeaways
- →USEFUL method reduces simplicity bias by clustering examples based on early network outputs and upsampling underrepresented data.
- →Sharpness-aware minimization (SAM) learns features more uniformly compared to standard gradient descent, making it less susceptible to simplicity bias.
- →The approach achieves state-of-the-art performance on CIFAR10, STL10, CINIC10, and Tiny-ImageNet datasets with ResNet architectures.
- →The method can be combined with existing SAM variants and data augmentation strategies for improved results.
- →Early training examples containing easily-learned features are separable from others based on model output patterns.
