최신 NVIDIA-Certified Associate NCA-GENM 무료샘플문제 (Q17-Q22):

질문 # 17
You are tasked with evaluating a multimodal A1 model that combines image and text inputs to generate product descriptions. You observe that the model performs well on common product categories (e.g., clothing, electronics) but struggles with niche categories (e.g., antique furniture, scientific instruments). Which of the following strategies would be MOST effective in improving the model's performance on niche categories?

A. Fine-tune the model on a dataset specifically curated for niche product categories.
B. Increase the overall size of the training dataset.
C. Implement data augmentation techniques to create synthetic data for niche categories.
D. Decrease the learning rate during training.
E. Replace the image encoder with a more powerful architecture.

정답：A

설명：
Fine-tuning on a niche dataset addresses the specific lack of knowledge about those categories. While other options might offer marginal improvements, targeted fine-tuning is the most direct and effective approach. Data augmentation (E) could help, but is secondary to using real-world data for fine-tuning.

질문 # 18
Consider a scenario where you are building a system for emotion recognition using facial expressions (images) and spoken words (audio). You plan to use a Convolutional Neural Network (CNN) for image feature extraction and a Recurrent Neural Network (RNN) for audio feature extraction. You want to combine the features learned by these networks using a cross-modal attention mechanism. Which of the following statements BEST describes how cross-modal attention can improve the performance of your system?

A. Cross-modal attention forces the CNN and RNN to learn identical feature representations.
B. Cross-modal attention reduces the computational complexity of the model by simplifying the feature extraction process.
C. Cross-modal attention ensures that the data from both modalities is perfectly aligned in time.
D. Cross-modal attention is only effective when the data from both modalities is perfectly synchronized.
E. Cross-modal attention allows the model to focus on the most relevant parts of one modality based on the information from the other modality.

정답：E

설명：
Cross-modal attention enables the model to selectively focus on the most relevant information from one modality by attending to the cues provided by the other modality. This allows the model to learn more nuanced relationships between the modalities and improve overall performance. It doesn't force identical feature representations or reduce computational complexity. While synchronization can help, attention mechanisms can still function even without perfect temporal alignment.

질문 # 19
Which of the following statements accurately describes the role of attention mechanisms in Transformer-based multimodal models?
(Select all that apply)

A. Attention mechanisms allow the model to focus on the most relevant parts of the input sequence when generating the output.
B. Attention mechanisms enable the model to learn relationships between different modalities, such as images and text.
C. Attention mechanisms are used to compress the input sequence into a fixed-length vector representation.
D. Attention mechanisms prevent vanishing gradients during training of deep neural networks.
E. Attention mechanisms are primarily used to reduce the computational cost of processing long sequences.

정답：A,B

설명：
Attention mechanisms enable the model to selectively focus on relevant parts of the input and learn relationships between modalities. They don't compress the input into a fixed-length vector, nor are they primarily for reducing computational cost or preventing vanishing gradients (although they can indirectly help with the latter).

질문 # 20
You are working on a multimodal AI model that generates images from text descriptions. You notice that the generated images often lack fine-grained details and appear blurry. Which of the following techniques is LEAST likely to improve the visual quality of the generated images?

A. Training with a larger dataset of higher-resolution images.
B. Using a perceptual loss function that penalizes differences in high-level features.
C. Increasing the latent space dimensionality of the generative model.
D. Reducing the batch size during training.
E. Employing a convolutional neural network (CNN) with strided convolutions for upsampling.

정답：D

설명：
Reducing the batch size during training often leads to more unstable training and can actually worsen the quality of generated images, especially in generative adversarial networks (GANs) or similar models. The other options (A, B, C, E) are all techniques commonly used to improve the detail and sharpness of generated images. Larger latent space allows more nuanced representations. Perceptual losses encourage the model to generate realistic-looking images. Improved upsampling avoids checkerboard artifacts. More high-res data helps.

질문 # 21
You're using a diffusion model to generate high-resolution images. You notice that the generated images often contain artifacts and inconsistencies. Which of the following techniques could help improve the image quality?

A. Employing classifier-free guidance during sampling.
B. Increasing the number of diffusion steps during training.
C. Decreasing the number of diffusion steps during sampling.
D. Training with a larger batch size.
E. Using a smaller image size during training.

정답：A,B

설명：
Increasing the number of diffusion steps allows the model to gradually refine the image and reduce artifacts. Classifier-free guidance provides a way to control the generation process and improve image quality by conditioning on a specific class or attribute. Training with a larger batch size may improve training stability but doesn't directly address artifact reduction. A smaller image size will reduce computational cost but doesn't necessarily improve quality at the desired resolution. Decreasing the number of diffusion steps can lead to lower-quality images with more artifacts.
