NVIDIA Generative AI Multimodal Sample Questions (Q361-Q366):

NEW QUESTION # 361
You are building a Generative A1 application that processes images and text. The image data has missing pixel values, and the text data contains inconsistencies in abbreviations. Which data preprocessing techniques are MOST suitable to address these issues effectively?

  • A. Image: Replacing missing pixels with zero; Text: Ignoring abbreviations during analysis.
  • B. Image: Median imputation for missing pixels; Text: Using a fuzzy matching algorithm to correct inconsistencies in abbreviations.
  • C. Image: KNN imputation for missing pixels; Text: Applying regular expressions to expand abbreviations.
  • D. Image: Deleting rows with missing pixel values; Text: Removing all abbreviations from the text data.
  • E. Image: Mean imputation for missing pixels; Text: Standardizing abbreviations using a predefined mapping.

Answer: B,C

Explanation:
KNN imputation is more robust than mean imputation for images as it considers neighboring pixels. Regular expressions and fuzzy matching provide more accurate abbreviation handling compared to simply removing or ignoring them. KNN imputation and Median imputations both can work well. Fuzzy Matching can also resolve ambiguities in abreviations


NEW QUESTION # 362
You are developing a system that generates 3D models from text descriptions. The system currently produces models that are geometrically accurate but lack fine-grained surface details and realistic textures. Which of the following steps would be MOST effective in improving the visual realism of the generated 3D models?

  • A. Reduce the size of the training dataset.
  • B. Use a simpler text encoder to focus on geometric information.
  • C. Increase the number of polygons used to represent the 3D models.
  • D. Rely solely on procedural generation techniques.
  • E. Train a separate texture generation model conditioned on the text description and the generated 3D geometry.

Answer: E

Explanation:
Training a separate texture generation model allows for specializing in generating realistic surface details and textures based on both the text description and the underlying 3D geometry. Increasing polygon count (A) can help, but doesn't address texturing. Simplifying the text encoder or reducing the dataset is counterproductive. Solely relying on procedural generation might lead to lack of variability.


NEW QUESTION # 363
Consider the following scenario: You're training a GAN for generating high-resolution images (e.g., 1024x1024). You notice that the training process is unstable, with the generator and discriminator constantly oscillating. Which of the following architectural modifications and training techniques could help stabilize the training process?

  • A. Increasing the learning rate of both the generator and discriminator.
  • B. Using Wasserstein GAN (WGAN) with gradient penalty (GP).
  • C. Applying batch normalization in both the generator and discriminator.
  • D. Replacing standard convolutional layers with transposed convolutional layers in the generator.
  • E. Using ReLU activation functions in the discriminator.

Answer: B,C

Explanation:
WGAN with gradient penalty (GP) addresses the instability caused by the Jensen-Shannon divergence used in standard GANs. Batch normalization can help stabilize training by reducing internal covariate shift. Transposed convolutions are a common practice but don't inherently stabilize training. Increasing the learning rate can exacerbate instability. ReLU activation can lead to vanishing gradients.


NEW QUESTION # 364
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. Spatial attention in the image encoder, conditioned on the text embedding (e.g., attention over image features based on text query).
  • B. Global average pooling of image features.
  • C. Temporal attention in a video encoder.
  • D. Self-attention in the text encoder (e.g., Transformer).
  • E. Channel attention in the image encoder (e.g., Squeeze-and-Excitation).

Answer: A

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 # 365
Consider the following code snippet, where you are trying to load image and text data for a multimodal model. What is the most likely cause of error if the code fails during the image loading step?

  • A. The system doesn't have CUDA drivers installed.
  • B. The image files are corrupted or in an unsupported format.
  • C. The text data is not in IJTF-8 encoding.
  • D. The batch size is too large.
  • E. The learning rate is set too high.

Answer: B

Explanation:
Since the error occurs specifically during the image loading step, the most likely cause is related to the image files themselves. Corrupted files or unsupported formats would prevent the image loading library from successfully reading the images. The other options are less likely to cause an error specifically during image loading.
