UnverifiedThe HNSW algorithm has been adopted by mainstream vector libraries such as Chroma and Weaviate due to its excellent balance between high recall rate and low latency.65% similarUnverifiedThe choice of synchronization strategy depends on trade-offs across three dimensions: data change frequency, timeliness requirements, and data scale versus cost; a pragmatic combination is to use incremental updates as the primary method, supplemented by periodic full rebuilds as a consistency check.64% similarUnverified底层模型更换后，即便微小的输出分布变化也可能导致此前校准的安全护栏过度拦截或防护失效，需要重新标注和调试64% similar
