Question 6

+1 markOne correct option

You have a pretrained CNN backbone and only 500 labeled images for a new task. A strong first baseline is:

  1. A

    Fine-tune the entire network immediately using a very small learning rate to preserve pre-trained features

  2. B

    Freeze backbone, train a new classifier head; optionally unfreeze later with smaller LR

  3. C

    Train a completely new architecture from scratch using heavy data augmentation to compensate for the lack of data

  4. D

    Unfreeze the backbone from the bottom layers upwards, gradually increasing the learning rate

Show answer

Correct answer

  • B
