A new research paper titled "Large Pretraining Datasets Don't Guarantee Robustness after Fine-Tuning in Image Classification" suggests that fine-tuning models pretrained on massive datasets can lead to significant catastrophic forgetting and a loss of out-of-distribution generalization. The researchers propose the Robustness Inheritance Benchmark (ImageNet-RIB) to evaluate this phenomenon. Their findings indicate that models pretrained on larger, more diverse datasets like LAION-2B may experience greater robustness losses compared to those trained on smaller datasets, challenging the assumption that larger pretraining always leads to better downstream performance. AI
IMPACT Suggests that the scale of pretraining data may not directly translate to better robustness after fine-tuning, potentially impacting strategies for model development.
