Abrégé
(EN)
The invention relates to the artificial intelligence, and provides a directional advertisement putting method and device and a computer readable storage medium. The method comprises the steps of calculating the similarity of the label vectors of two users, and obtaining a score 1; calculating the similarity of the two user behavior vectors to obtain a score 2; modeling a user vector by using an alternating least square algorithm, obtaining the user vector and an advertisement vector by using a random gradient descent optimization algorithm, calculating the similarity of the user vectors of twousers to obtain a score 3, and weighting the score 1 to the score 3 linearly to obtain a score 4; carrying out XGBOOST, SVM and GBDT on the user behavior vector, the user interest label vector and the user vector respectively to obtain the corresponding scores as FM input, obtaining a score 5, and weighting the score 4 and the score 5, outputting the final user similarity, comparing the final user similarity with a similarity threshold, and selecting the user higher than the similarity threshold as a target customer group.

本方案涉及人工智能,提供一种定向广告投放方法、装置及计算机可读存储介质,方法包括:计算两个用户的标签向量的相似度,获得分值1;计算两个用户行为向量的相似度,得到分值2;利用交替最小二乘算法对用户向量建模,并通过随机梯度下降优化算法,得到用户向量和广告向量,并计算两个用户的用户向量的相似度,得到分值3,对分值1至分值3线性加权得到分值4。将用户行为向量、用户兴趣标签向量、用户向量分别经过XGBOOST、SVM、GBDT得到相应的分数作为FM的输入,得到分值5,再对分值4和分值5进行加权组合,输出最终的用户相似度,将最终的用户相似度与相似度阈值比较,选择高于相似度阈值的用户作为目标客群。
