Amazon Web Services Updated AIF-C01 Exam Questions and Answers by kaitlyn

Fine-tuning involves training an already pre-trained FM on a smaller, labeled dataset for task specialization.

Data selection is about curating training data.

Pre-training is the initial training phase on massive datasets.

Evaluation happens after training, not during.

Increasing the number of epochs during model training allows the model to learn from the data over more iterations, potentially improving its accuracy up to a certain point. This is a common practice when attempting to reach a specific level of accuracy.

Option B (Correct): "Increase the epochs": This is the correct answer because increasing epochs allows the model to learn more from the data, which can lead to higher accuracy.

Option A: "Decrease the batch size" is incorrect as it mainly affects training speed and may lead to overfitting but does not directly relate to achieving a specific accuracy level.

Option C: "Decrease the epochs" is incorrect as it would reduce the training time, possibly preventing the model from reaching the desired accuracy.

Option D: "Increase the temperature parameter" is incorrect because temperature affects the randomness of predictions, not model accuracy.
