Light 科研主线第 2 步·数据工程:**找得到且用得起的数据**(来源/许可/版本/大小/split)+ **提 idea 前先判数据可行性** (数据够不够支撑研究/统计功效)+ **防数据泄漏**(顶会拒稿高频雷)。何时用:用户要找/选/下载公开数据集,或给了数据问 "能不能做研究/够不够/质量行不行" / 要清洗·处理缺失异常·特征工程·划分数据集·数据增强 / 自建数据集(采集·标注规范· 隐私合规·发布) / 怀疑训练测试串了数据(泄漏) / 提 idea 前评数据基础。 触发词:数据够不够 / 数据可行性 / 数据质量 / 数据泄漏 / 防穿越 / train test 重叠 / 怎么划分 / 交叉验证 / 标注规范 / 一致性 IAA / 自建数据集 / 样本量够吗 / 统计功效 / 找数据集 / 数据许可 / dataset search / data leakage / feasibility / data split / annotation。核心纪律: **数据泄漏 = critical 一票否决**(标准化早于划分/时序穿越/实体重叠/目标编码穿越);**数据不足以支撑 idea = 拦在 idea 前(回边 2⊣3,补数据/改 idea)**;功效是经验阈值非 power analysis;泄漏检测是启发式有边界,不吹"查全了"。
