What is the name of the method that transforms categorical features into a series of binary indicator feature variables?

ALeave-one-out encoding

BTarget encoding

COne-hot encoding

DCategorical

EString indexing

Show Suggested Answer

Suggested Answer: C

The method that transforms categorical features into a series of binary indicator variables is known as one-hot encoding. This technique converts each categorical value into a new binary column, which is essential for models that require numerical input. One-hot encoding is widely used because it helps to handle categorical data without introducing a false ordinal relationship among categories. Reference:

One-hot encoding, that's the one! I remember learning about this in my machine learning class. It's a really useful technique for converting categorical features into a format that can be used in models.

I'm a little confused by this question. There are a few different techniques for dealing with categorical data, like leave-one-out encoding and target encoding. I'm not 100% sure which one is being asked about here.

Hmm, I'm a bit unsure about this one. I know there are a few different ways to handle categorical features, but I can't quite remember the specific name for the method that creates binary indicator variables. I'll have to think this through carefully.

I'm pretty sure this is asking about one-hot encoding, which is a common technique for transforming categorical features into a format that can be used in machine learning models.
