- 发生了什么
- Research shows semantic similarity detection requires joint computation between sentence pairs, not geometric properties of independent embeddings alone.
- 为何重要
- Matters for engineers building retrieval, RAG, and semantic search systems relying on frozen encoders or embedding-based reranking.
- 注意
- Joint forward passes achieve 0.90-0.96 AUC but independent encodings plateau near 0.55-0.70; transfer learning and generalization remain unclear.
