LAMB: LLM-based Audio Captioning with Modality Gap Bridging via Cauchy-Schwarz Divergence
🤖AI Summary
Researchers have developed LAMB, a new AI framework that improves automated audio captioning by better aligning audio features with large language models through Cauchy-Schwarz divergence optimization. The system achieved state-of-the-art performance on AudioCaps dataset by bridging the modality gap between audio and text embeddings.
Key Takeaways
- →LAMB introduces a Cross-Modal Aligner that uses Cauchy-Schwarz divergence to better align audio and text embeddings in LLMs.
- →The framework includes a Two-Stream Adapter for extracting semantically enriched audio embeddings.
- →A Token Guide component directly computes scores within the LLM text embedding space to improve caption generation.
- →The system achieved state-of-the-art performance on the AudioCaps benchmark dataset.
- →Previous approaches failed to fully utilize LLM reasoning capabilities due to poor cross-modal alignment.
