AI0-001 AI Concepts and Techniques Practice Question

A data analyst wants to use a model that provides feature importance scores to understand which factors most influence customer churn. They also need the model to handle both numerical and categorical data with minimal preprocessing. Which algorithm is BEST suited?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Random forest

Random forests provide feature importance, handle mixed data types, and require little preprocessing.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Random forest

    Why this is correct

    Random forests output feature importance, handle mixed data, and are robust to scaling.

  • Support vector machine (SVM) with RBF kernel

    Why it's wrong here

    SVMs do not natively provide feature importance and require feature scaling.

  • Logistic regression

    Why it's wrong here

    Logistic regression coefficients can indicate direction but not direct importance, and requires encoding categorical variables.

  • k-nearest neighbours (k-NN)

    Why it's wrong here

    k-NN is sensitive to scaling and provides no feature importance.
