Your Team Trained and Tested a DNN Regression Model with Good

question 17

Multiple Choice

Your team trained and tested a DNN regression model with good results. Six months after deployment, the model is performing poorly due to a change in the distribution of the input data. How should you address the input differences in production?

• A) Create alerts to monitor for skew, and retrain the model.
• B) Perform feature selection on the model, and retrain the model with fewer features.
• C) Retrain the model, and select an L2 regularization parameter with a hyperparameter tuning service.
• D) Perform feature selection on the model, and retrain the model on a monthly basis with fewer features.

Definitions:

Predetermined Overhead Rate

A rate used to allocate manufacturing overhead cost to products or job orders, based on expected overhead costs and a chosen allocation base.

Variable Component

A variable component refers to a part of a cost or expense that varies directly with the level of output or activity.

Fixed Component

A portion of total costs that remains constant, regardless of changes in the production level or sales volume.

Underapplied

A situation where the allocated manufacturing overhead costs are less than the actual overhead costs incurred.
