Exam NCA-GENM Topic 1 Question 53 Discussion

Actual exam question for NVIDIA's NCA-GENM exam
Question #: 53
Topic #: 1
You are tasked with building a multimodal generative AI model to create marketing content from product images and descriptions. The image encoder uses a pre-trained ResNet50 model, and the text encoder uses a pre-trained BERT model. After initial training, the generated content frequently misinterprets the image. Which of the following strategies is MOST effective in improving the model's ability to correctly interpret the image within the multimodal context?

Suggested Answer: B Vote an answer

Fine-tuning ResNet50 with a relevant image dataset and a contrastive loss function directly addresses the issue of misinterpreting the image. Freezing weights prevents learning, increasing BERT's learning rate imbalances the model, and a simpler image encoder might lose crucial image details. Decreasing batch size can improve generalization but isn't the primary solution for image misinterpretation.
