研究:开放索引在搜索推荐系统中提供效率

一篇新的研究论文探讨了共享搜索和推荐索引之间的权衡,发现双编码器检索系统可以在不显著损失准确性的情况下保持索引对新项目的开放。这种方法与需要为新内容重新训练的传统ID-softmax推荐器形成对比。该研究使用MovieLens 1M和MIND等数据集,量化了开放索引和重新训练模型之间的准确性差距,并强调虽然开放索引更有效,但在大规模实现精确质量训练仍然是一个悬而未决的挑战。 AI

影响 这项研究可能带来更高效的推荐系统,能够更好地处理新内容,而无需持续重新训练。

    保持开放索引:共享搜索和推荐的推荐侧成本

    A shared search-and-recommendation index must score new items from features alone because search has no exploration slot. In a public log covering both surfaces over one catalog, $38.6\%$ of held-out query-search impressions show an item never previously shown or visited. For use…
