AWS Certified AI Practitioner AIF-C01 Practice Question

A team trains a text classification model that achieves 98 % accuracy on the training data but only 60 % on a held-out validation set. Which statement best describes the model's bias-variance condition?

  • The model has high variance, indicating overfitting to the training data.

  • The accuracy gap is due only to random noise; bias and variance are unaffected.

  • The model has high bias, indicating underfitting on both training and validation data.

  • The model demonstrates an optimal bias-variance tradeoff.

Settings & Objectives
Random Mixed
Questions are selected randomly from all chosen topics, with a preference for those you haven’t seen before. You may see several questions from the same objective or domain in a row.
Rotate by Objective
Questions cycle through each objective or domain in turn, helping you avoid long streaks of questions from the same area. You may see some repeat questions, but the distribution will be more balanced across topics.

Check or uncheck an objective to set which questions you will receive.
