Researchers have developed CARD, a novel encoder-free audio captioning model that significantly reduces inference costs by removing the audio encoder. The model distills knowledge from a pretrained audio teacher, CLAP-HTSAT, by strategically routing its representations to different components: perceptual stages to the projector and semantic stages to the LLM. This approach improves performance on benchmark datasets like AudioCaps and Clotho, achieving a score of 55.4 without an encoder during inference. AI
IMPACT This research could lead to more efficient audio captioning systems by reducing computational requirements during inference.
