天池-印象盐城-乘用车销量预测大赛 的复赛B榜14名的渣渣分享一下渣思路和渣代码...希望能造福一部分比我还新的新手...
复赛

代码说明.md。
初赛
初赛线下做，复赛线上平台做。上面说的截图和代码都是复赛的。
初赛特征跟复赛类似，只是有些复赛能做的特征，初赛的数据做不出来，自然就没有啦，偷个懒就不再详述初赛特征了。
代码见目录初赛相关/src/，其中feature_extraction下是各类特征的提取，特征含义见注释；先分别提取各类特征后，执行拼出最终特征.ipynb中的代码即可得到完整的提完特征的数据集，再运行src/train/train-v0.5.ipynb中的代码即可生成结果。其他的思路啥的，见.ipynb中的说明以及复赛的解题思路说明。
不过有很多特征是应当被丢弃的。这个版本里训练时使用的可能并不是最好的一组特征。
