Researchers have developed a new framework called Evolutionary Dynamic Loss (EDL) for pretraining classification losses without using real data. EDL learns a transferable loss function by generating synthetic prediction-label pairs and optimizing the loss as a neural network. The system uses an evolutionary strategy with chaotic mutation to explore loss function possibilities, aiming for robust performance. Experiments demonstrated that EDL can effectively replace standard cross-entropy loss and achieve comparable or better accuracy on image classification tasks. AI
