探究 训练时间对 模型收益影响?

训练集长时间 (5-10年) VS 训练集 短时间 (6个月-1,2年) 会对模型的数据造成怎么样的影响?

长时间: 从05年开始往后 到21年 增加数据 首先是标注的训练数据发生了改变, 其次是 模型中 因子的特征权重发生改变 再然后是 ndcg的评价也发生了改变 最后 整个模型的预测结果也会产生偏差

简单评价:长时间训练 搜索出来的回测结果  回测时间更长,得出结论更稳定  也更容易 过拟合


短时间 从21年开始往前 到20年 增加数据 变化同上 但数据量更少,有可能 NDCG反而提高 收益也更高

简单评价:短时间训练 搜索出来的回测结果  在未来回测更陡峭 收益有可能更高  也更容易欠拟合




探究 有没有 一些较好的训练时间作为参考?

05年-16年,13-19年,10-20年都可以试试。

探究 是策略思路重要还是因子重要?

1.好的策略设计思路,能节省你挖掘因子的时间,同时,聚焦某一个领域去钻研,

也更容易找到适配的组合,挖掘出好的因子模型。 (比如追涨的逻辑,就要配合动量因子,做追龙头的逻辑,就要配合波动率因子和收益率因子)

2.因子和策略的表现跟市场是强相关的。

有的年份 小市值股票厉害,风格暴露在小市值上的模型,超额收益更多,有的年份则相反 一类因子其实也只是一种套路或者说一种市场偏好选股风格的集成, 如何去高效利用好这种因子, 才是我们应该去研究的问题。 平常做模型的因子如果想不到在哪来, 可以在因子看板里面去找找。
