1、自定义学生信息、课程信息、老师信息三者的具体描述 2、自定义example.py和file_exe.py模块,分别用以定义(1)中的描述信息和作为启动文件 3、启动文件中主要包含5个方法,包括星号(“*”)分割线设置、初始化课程信息并装载入列表返回、初始化老师信息并装载入列表返回、遍历课程对象并绑定老师至课程对象的对应属性...
This recipe along with the two following it will be centered around automatic feature selection. I like to think of this as the feature analogue of parameter tuning. In the same way that we cross-validate to find an appropriately general parameter, we can find an appropriately general subset o...
当然了,使用missing_stats属性也能查到每列的缺失值,只不过结果是根据缺失值的大小排过序的: 要查看待移除特征,我们可以读取FeatureSelector的ops属性,这是一个Python特征词典,特征会以列表的形式给出: 最后,我们可以绘制一张所有特征的缺失值分布图: part 2、单个唯一值特征处理 此方法相当基础:找出任何有单个唯一...

R的 energy 包里提供了距离相关系数的实现,另外这是Python gist的实现。 >x=runif(1000,-1,1)>dcor(x,x**2)[1]0.4943864 尽管有 MIC 和 距离相关系数 在了,但当变量之间的关系接近线性相关的时候,Pearson相关系数仍然是不可替代的。 第一,Pearson相关系数计算速度快,这在处理大规模数据的时候很重要。
Hypothesis Test in Six Steps Explanation with Math and Python Let us define the improvements of features as random variables \{X_k\} , denote \{X_k^o\} as the observed average improvement for each feature (Observed in the example), and define \mu as the improvement threshold (2% in the...
DSelect-k for Per-example Gating,这里还要额外提到最后的一个部分。 这里其实就是对静态门控机制 DSelect-k for Static Gating 的一个小细节上的修改,具体的修改的是啥,在这一节的总结里会写。 前面洋洋洒洒一大堆,我们只是在描述一个gate,而一个gate对应一个task,如果多个task则需要使用多个gate,因此我们需要...
The computational framework only requires the proximal operator for each regularizer to be readily computable, and the implementation is available in an open source python package pysr3 , consistent with the sklearn standard. The numerical results on simulated data sets indicate that the proposed ...
