- A travel app wants its assistant to check live seat availability and then book a reservation by calling the airline's booking API, with the model deciding when each call is needed. Which Amazon Bedrock feature supports this?Medium
- A data scientist training a convolutional classifier notices the model memorizes its training images. Which regularization method should be added so that, during each training step, a random subset of hidden units is silenced?Medium
- A research lab must train a multi-billion-parameter language model across hundreds of accelerator instances for several weeks. Hardware failures must be detected and faulty nodes replaced automatically without restarting the whole run from scratch. Which SageMaker option fits?Hard
- A pharmaceutical company has millions of unlabeled internal research articles. It wants the foundation model to absorb this specialized vocabulary and writing patterns before any task-specific training, without supplying question-answer pairs. Which customization method does this?Medium
- A courier company predicts delivery durations in minutes. Observed labels stay between 0 and 100 and never sit near zero, and planners want an error figure they can quote as a percentage of the true duration. Which metric should the team report?Medium
- A vision team finds that early epochs on a mixed-difficulty dataset are unstable. They reorder training so clean, obvious images appear first and ambiguous, noisy images are phased in later, and convergence improves. Which training strategy is this?Hard
- While reviewing a convolutional detector, an engineer explains that a neuron in a deep layer reacts to a wide area of the original image. What is this area called?Hard
- Training a deep recurrent network occasionally produces enormous gradient values that wreck an epoch. Which remedy directly addresses this?Medium
- A plain recurrent network fails to learn dependencies that span dozens of time steps. Which explanation and remedy are correct?Hard
