NVIDIA Generative AI Multimodal Sample Questions (Q202-Q207):

NEW QUESTION # 202
Consider you are working on a project that aims at generating photorealistic images from segmentation maps, using a conditional GAN architecture. The training process is unstable, frequently exhibiting mode collapse and artifacts. Describe a series of techniques, ranked by their likely impact, to mitigate these issues.

  • A. 1. Increase batch size. 2. Decrease learning rate. 3. Add more convolutional layers.
  • B. 1. None of the above
  • C. 1. Implement Spectral Normalization. 2. Use PatchGAN discriminator. 3. Apply data augmentation (e.g., random flips, jitter).
  • D. 1. Reduce the number of layers in the discriminator. 2. Increase the learning rate of the generator. 3. Disable batch normalization.
  • E. 1. Switch to a Transformer-based architecture. 2. Use a larger dataset. 3. Decrease the number of channels in the generator.

Answer: C

Explanation:
Spectral Normalization stabilizes training by limiting the Lipschitz constant of the discriminator. PatchGAN discriminator focuses on local image patches, improving detail and reducing artifacts. Data augmentation increases the diversity of training data and improves generalization. Thus, Option B presents the most impactful techniques, ranked appropriately. Other options either suggest less impactful techniques or recommend steps that could worsen the issues. Mode Collapse can be avoided here with data augmentation.


NEW QUESTION # 203
Consider the following Python code snippet using PyTorch, intended for fusing image and text features in a multimodal model. Assume 'image_featureS and 'text_features' are tensors of shape Which of the following fusion methods is implemented in this code?

  • A. Element-wise Addition
  • B. Tensor Product
  • C. Cross-modal Attention
  • D. Gated Attention
  • E. Concatenation

Answer: E

Explanation:
The code snippet uses 'torch.cat((image_features, text_features), dim=l y , which concatenates the image and text features along the feature dimension (dim=l This is a concatenation-based fusion method. Addition would involve 'image_features + text_featureS. Gated or cross-modal attention would involve learnable weights and attention mechanisms. Tensor product involves reshaping and matrix multiplication of the features. The given answer is A, but the code snippet is missing. Please provide the code for an accurate explanation.


NEW QUESTION # 204
You have trained a multimodal model to generate descriptions for recipes, using images of the finished dish as one modality and a list of ingredients as another. When evaluating the generated descriptions, you notice the descriptions are factually correct in terms of ingredients but often fail to capture the stylistic nuances or tone of professionally written recipes. Which evaluation strategy would provide the most insightful feedback on this aspect of the model's performance?

  • A. Calculate the BLEU score between the generated descriptions and a set of reference recipes.
  • B. Use a pre-trained language model to assess the fluency and coherence of the generated descriptions.
  • C. Conduct a human evaluation where individuals rate the generated descriptions based on factors such as informativeness, clarity, and stylistic appropriateness.
  • D. Compute the ROUGE score between the generated descriptions and a set of reference recipes.
  • E. Measure the perplexity of the generated descriptions using a language model trained on a corpus of recipe books.

Answer: C

Explanation:
Human evaluation is the most reliable way to assess subjective aspects of the generated text, such as stylistic appropriateness. While automated metrics like BLEU, ROUGE, and perplexity can provide insights into factual accuracy and fluency, they do not capture the nuances of style and tone as effectively as human judgment. Therefore, the correct answer is (D).


NEW QUESTION # 205
You are working on a multimodal sentiment analysis task where you have both textual reviews and corresponding product images. You want to build an attention mechanism to identify the most relevant parts of the image that contribute to the sentiment expressed in the text. Which of the following attention mechanisms is BEST suited for generating spatial attention maps highlighting these relevant regions in the image?

  • A. Global average pooling of image features.
  • B. Spatial attention in the image encoder, conditioned on the text embedding (e.g., attention over image features based on text query).
  • C. Channel attention in the image encoder (e.g., Squeeze-and-Excitation).
  • D. Temporal attention in a video encoder.
  • E. Self-attention in the text encoder (e.g., Transformer).

Answer: B

Explanation:
Spatial attention, conditioned on the text embedding, directly addresses the task. This mechanism allows the model to focus on specific regions of the image that are most relevant to the sentiment expressed in the text. The text embedding acts as a 'query' to attend over the image features, generating a spatial attention map that highlights the contributing regions. Self attention in text (A) focuses on relationships within the text itself. Channel attention (B) focuses on feature channel importance, not spatial localization related to the text. Temporal attention (D) is irrelevant for static images. Global average pooling (E) loses spatial information.


NEW QUESTION # 206
You are fine-tuning a pre-trained multimodal model for a specific task that involves generating short video clips from text prompts. The pre-trained model was trained on a large dataset of diverse videos and text descriptions. However, you observe that the fine-tuned model tends to generate video clips that are visually appealing but often deviate significantly from the meaning of the text prompts. Which of the following techniques is LEAST likely to improve the semantic consistency between the generated video clips and the text prompts?

  • A. Implement a reinforcement learning objective that rewards the model for generating videos that are semantically similar to the text prompts.
  • B. Adding a contrastive loss to the fine-tuning process.
  • C. Use a lower learning rate during fine-tuning.
  • D. Augment the fine-tuning dataset with synthesized video-text pairs generated by another model.
  • E. Freeze the weights of the video encoder during fine-tuning.

Answer: E

Explanation:
Freezing the weights of the video encoder will prevent it from adapting to the specific nuances of the fine-tuning task, potentially hindering the model's ability to generate videos that accurately reflect the meaning of the text prompts. A lower learning rate, reinforcement learning, data augmentation, or contrastive learning are all techniques that can help improve semantic consistency.
