一个包含1000条用户-物品交互记录的样本数据集，用于TAAC2026竞赛。该数据集采用扁平列布局——所有特征都存储为单独的顶级列，而不是嵌套的结构体或数组。数据集包括5个ID和标签列、46个用户整数特征列、10个用户密集特征列、14个物品整数特征列以及45个来自4个行为领域的序列特征列，总共120列。A sample dataset containing 1,000 user-item interaction records for the TAAC2026 competition. This dataset adopts a flat columnar layout, where all features are stored as separate top-level columns rather than nested structures or arrays. The dataset includes 5 ID and label columns, 46 user integer feature columns, 10 user dense feature columns, 14 item integer feature columns, and 45 sequential feature columns from 4 behavioral domains, with a total of 120 columns.
