✨ FAQ NEW
Course: machine-learning-zoomcamp
Section: module-3 (This is directly about one-hot encoding for classification and specifically mentions
DictVectorizer, so it fits Module 3’s topic area (Churn prediction / one-hot encoding).)Related Issue: #444
Question
Can I use
pd.get_dummiesinstead ofDictVectorizerfor one-hot encoding (Homework 3 Q4)?Decision Rationale
The proposal asks specifically whether
pd.get_dummiescan be used instead ofDictVectorizerfor one-hot encoding in Homework 3 Q4, and it gives guidance on the key risk (mismatched columns across splits). None of the existing FAQs addresspd.get_dummiesvsDictVectorizerwith train/validation alignment advice.Placement Details
