NVIDIA researchers have developed X-Token, a novel method for knowledge distillation that allows smaller AI models to learn from larger, incompatible teacher models. Unlike previous methods that struggle with different tokenizers, X-Token uses dynamic programming for span alignment and a projection matrix to map token distributions. This approach overcomes limitations in existing techniques like GOLD, particularly in handling fragmented text and preserving alignment signals, leading to improved performance on tasks like GSM8k.
