Researchers have introduced a new framework called Decision Boundary-aware Generation (DBG) to address the challenge of long-tailed data bias in machine learning. This bias typically leads to poor accuracy for less frequent 'tail' classes. DBG aims to improve tail class performance by generating synthetic data that specifically targets the areas near decision boundaries, promoting more separable feature representations and reducing inter-class overlap. Experiments on standard benchmarks show that DBG effectively enhances both tail class and overall accuracy. AI
