In late August,Neo4j updated its database platform to include vector search. As generative AI has gained momentum in the 11 months since OpenAI released ChatGPT, which marked significant improvement in generative AI and large language model functionality,vector search has become more i...
PageRank最初是由谷歌联合创始人拉里·佩奇(LarryPage)和谢尔盖·布林(SergeyBrin)于1996年在斯坦福大学(StanfordUniversity)开发的,是一个关于新型搜索引擎的研究项目的一部分。自那以后,Google Search一直使用它在搜索引擎结果中对网页进行排名。 总之,PageRank通过计算来自相邻节点的传入关系的数量来估计节点的重要性,这...
