Overfitting — Google Cloud ML Engineer Practice Questions
Overfitting occurs when a model learns the training data so precisely, including its noise and random fluctuations, that it performs well on training examples but poorly on new, unseen data. It is one of the most common failure modes in ML and is typically diagnosed by a large gap between training accuracy and validation accuracy. The Google Cloud ML Engineer exam tests candidates on recognizing overfitting symptoms, selecting remedies such as collecting more data, applying regularization, using dropout, simplifying the model architecture, or leveraging early stopping in Vertex AI training jobs.
