Lesson 2 : Introduction to Machine Learning

What are the common approaches for encoding categorical data

• One hot encoding

• Standardization

• Ordinal encoding

The scaling technique where we rescale the data to have mean = 0 and standard deviation = 1

• Standardization

• Normalization

What is the typical pipeline for a classification model using text data?

• vectorize text > normalize text > train model > deploy model

• train model > normalize text > vectorize text > deploy model

• normalize text > vectorize text > deploy model > train model

• normalize text > vectorize text > train model > deploy model
