Missing Values Handling in Machine Learning | Data Cleaning Tutorial 4
Показать описание
During the Machine Learning Data Cleaning process, you will often need to figure out whether you have missing values in the data set, and if so, how to deal with it. In this video,
I have demonstrated :-
1. Why Machine Learning Training DataSet has missing values?
2. Why missing values Treatment/Handling is required ?
3. Why the correct imputation method is required ?
There are various strategies to handle or impute the missing values in a dataset.
Removal or Deletion of missing value
- Impute missing values with Statistical way(Mean/Median/Mode)
- Prediction Model (Regression and Classification Model)
- Use sklearn Impute module (SimpleImputer , IterativeImputer, KNNImputer)
- Imputation using Deep Learning Library – Datawig
Below are the Python Functions which are used to impute the missing values in a dataset.
- Use Python fillna function
- Use Python dropna function
- Use Interpolation method
- Use python replace function
