A company wants to classify images of different objects based on custom features extracted from...

Comprehensive and Detailed Explanation From Exact AWS AI documents:

Fine-tuning a pre-trained deep learning model (transfer learning) provides the lowest development effort because:

The model already understands general visual features

Only minimal training is required on the custom dataset

Feature extraction is handled automatically

AWS guidance strongly recommends transfer learning for image classification tasks when development speed and efficiency are priorities.

Why the other options are incorrect:

A and D require extensive feature engineering and tuning.

C (GANs) are designed for data generation, not classification.
