Feature engineering is the process of using domain knowledge and insight into data to define features that enable machine learning algorithms to work successfully. Feature engineering is a fundamental part of the data preparation workflow for machine learning solutions.
What you will learn:
Qualities of effective features and how to assess them
Numeric techniques (quantization binning, binarization, transforms, scaling, normalization)
Text techniques (bag-of-x, filtering, n-grams, phrase detection)
Categorical data techniques (one-hot encoding, hashing, bin counting, etc)
Dimensionality reduction (PCA)
Nonlinear featurization (K-means clustering model stacking)
Image processing techniques (feature extraction)
Prerequisites:
Statistics
Data Analytics Literacy
Machine Learning Literacy
