OpenAI researchers have identified a phenomenon called "deep double descent" in various deep learning models, including CNNs, ResNets, and transformers. This occurs when models are not carefully regularized, causing performance to initially improve, then worsen, and then improve again as model size, data, or training time increases. The research indicates that in certain regimes, larger models can perform worse, more training data can be detrimental, and extended training can paradoxically reverse overfitting. AI
