Use data visualization. Visualization can reveal pathologies in the distribution of a feature or complicated relationships that could be simplified. Be sure to visualize your dataset as you work through thefeat
最简单直接方法就是直接点进去这个数据值的界面进行查看，但是在这个过程中我们需要额外关注以下几点的信息：首先是数据值的简介，这个可以在data card-about datasets这个栏当中找到。第二个数据值的大小。因为大部分的数据集它会告诉你它有多少的特征，也就是多少列也会显示包含了多少的样本，也就是多少行。那么有...

因为在我们初步选定了这个数据集之后,我们需要更进一步的搜集关于这个数据集的一些信息来确保它的数据就是我们可靠的以及有效的。最简单直接方法就是直接点进去这个数据值的界面进行查看,但是在这个过程中我们需要额外关注以下几点的信息:首先是数据值的简介,这个可以在data card-about datasets这个栏当中找到。第二个数据...
We find that most of the Kaggle datasets are characterized by higher intermittence and entropy than the M-competitions and that global ensemble models tend to outperform local single models. Furthermore, we find the strong performance of gradient boosted decision trees, increasing success of neural...
