摘要

摘要: 面向用户生成内容(User generated content, UGC)的进化搜索在大数据及个性化服务领域已引起广泛关注, 其关键在于基于多源异构用户生成内容构建用户认知偏好模型, 进而设计高效的进化搜索机制. 针对此, 提出融合注意力机制(Attention mechanism, AM)的受限玻尔兹曼机(Restricted Boltzmann machine, RBM)偏好认知代理模型构建机制, 并应用于交互式分布估计算法(Interactive estimation of distribution algorithm, IEDA), 设计含用户生成内容的个性化进化搜索策略. 基于用户群体提供的文本评论, 以及搜索物品的类别文本, 构建无监督受限玻尔兹曼机模型提取广义特征; 设计注意力机制, 融合广义特征, 获取对用户认知偏好高度相关特征的集成; 利用该特征再次训练受限玻尔兹曼机, 实现对用户偏好认知代理模型的构建; 根据用户偏好认知代理模型, 给出交互式分布估计算法概率更新模型以及物品适应度评价函数, 实现物品个性化进化搜索. 算法在亚马逊个性化搜索实例的应用验证了用户认知偏好模型的可靠性, 以及个性化进化搜索的有效性.

Abstract: User generated content (UGC)-oriented evolutionary search has attracted widespread attention in the field of big data and personalized services. The key is to construct a user cognitive preference model based on multi-source heterogeneous user generated content, and then design efficient evolutionary search mechanism. To solve this problem, this paper proposed a preference cognitive surrogate model based on restricted Boltzmann machine (RBM) with the attention mechanism (AM) in an interactive estimation of distribution algorithm (IEDA) to design personalized evolutionary search strategies with user generated content. Based on the text comments provided by user groups and the category text of searched items, an unsupervised restricted Boltzmann machine model is built to extract generalized features. The attention mechanism is designed to integrate generalized features to obtain the integration of highly relevant features of user cognitive preferences. These features are used to train a restricted Boltzmann machine to construct the surrogate model of user cognitive preferences. According to this surrogate model, a probability updating model of interactive estimation of distribution algorithm and a fitness evaluation function of searched items are given to realize personalized evolutionary search. The application of the algorithm in Amazon personalized search examples verifies the reliability of the user cognitive preference model and the effectiveness of personalized evolutionary search.
