基于内容的过滤的优势劣势
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
优势
- 模型不需要有关其他用户的任何数据,因为
系统会专门为该用户推荐合适的内容这使得
可以更轻松地扩展到大量用户
- 模型可以捕获用户的特定兴趣,
并能推荐一些其他用户很少会见到的小众产品
感兴趣的主题。
缺点
- 由于项目的特征表示是手动设计的,
在某种程度上,此方法需要很多领域知识。因此,
模型的优良程度只能与人工设计的特征相当。
- 该模型只能根据现有的兴趣爱好
用户。换句话说,该模型在基础上扩展的能力
用户的现有兴趣。

This makes it easier to scale to a large number of users.\n- The model can capture the specific interests of a user, and can recommend niche items that very few other users are interested in.\n\nDisadvantages\n\n- Since the feature representation of the items are hand-engineered to some extent, this technique requires a lot of domain knowledge. Therefore, the model can only be as good as the hand-engineered features.\n- The model can only make recommendations based on existing interests of the user. In other words, the model has limited ability to expand on the users' existing interests."]]
