在mysql之中，针对24小时内的数据按照半个小时进行一次统计数量： ```sql SELECT DATE_FORMAT(FROM_UNIXTIME(FLOOR(UNIX_TIMESTAMP(add_time) / 1800) * 1800), '%Y-%m-%d %H:%i') AS half_hour, COUNT(*) AS count FROM user_track.page_view WHERE add_time >=…

针对图对象进行向量化表示嵌入： 首先，通过node2vec方法，将node表示为向量 第二步，针对node向量矩阵，进行umap降维计算，对node进行排序，生成node排序序列 第三步，针对node排序序列进行SGT序列图嵌入，实现将网络图对象嵌入为一维向量
