Introduction

06:05

Master feature engineering for machine learning with a practical, hands-on approach, applying techniques from basic feature creation to PCA, imputation, encoding, regularization, and cross-validation using Python code.

Our Use Case - Housing Price Prediction Dataset

03:01

Apply feature engineering to a housing price dataset by median imputation for missing values, one-hot encoding neighborhoods, creating house age, log-transforming square footage, correlation analysis, and standardizing data.

Types of Features and Domain Knowledge

03:24

Identify and transform feature types—categorical, numerical, temporal, and text—to improve machine learning models. Leverage domain knowledge to guide feature creation, selection, and interaction terms for better performance and interpretability.

Handling Missing Data

09:03

Learn strategies to handle missing data, from mean, median, and mode imputation to modeling-based approaches like KNN and regression. Apply these to numerical and categorical features, including frequent category imputation.

Feature Transformation

01:57

Explore feature transformation techniques for machine learning, including scaling, normalization, log and power transformations, binning, and one hot encoding for categorical data.

Scaling and Normalization

05:40

Learn to scale and normalize features using standardization to zero mean and unit variance or min-max normalization to 0–1, improving model training on housing data.

Log Transformation, Power Transformation

05:16

Binning Numerical Variables

03:36

One-Hot Encoding vs. Label Encoding

04:07

Compare one-hot encoding and label encoding for transforming categorical data into numerical features, weighing dimensionality against potential ordinal assumptions in different datasets.
