What are the important data pre-processing techniques in python machine learning?
Answer Posted / Zasmendar Singh
Some important data preprocessing techniques in Python Machine Learning include: 1) Missing Value Handling - replacing missing values with mean, median, or mode; using interpolation or regression. 2) Data Cleaning - removing duplicates, outliers, and noisy data. 3) Feature Extraction - converting raw data into meaningful features, like using PCA for dimensionality reduction or Bag of Words for text analysis. 4) Data Normalization/Standardization: scaling the range of features to improve model performance.
