NVIDIA Generative AI Multimodal 認定 NCA-GENM 試験問題 (Q44-Q49):

質問 # 44
You are tasked with deploying a generative A1 model for image inpainting using Triton Inference Server. The model takes an image with masked regions as input and outputs the completed image. You need to pre-process the input image before sending it to the server.
Which pre-processing steps are crucial for ensuring optimal performance and accuracy of the inpainting model?

A. Converting the image to grayscale.
B. Sharpening the image to enhance details.
C. Resizing the image to a fixed resolution and normalizing pixel values to a specific range (e.g., [0, 1] or [-1, 1]).
D. Creating a binary mask indicating the regions to be inpainted.
E. Applying data augmentation techniques like random rotations and flips.

正解：C、D

解説：
Resizing and normalization ensure the input image conforms to the model's expected input size and data range. A binary mask is essential to indicate which regions the model should inpaint. Converting to grayscale would remove color information, hindering the inpainting process. Data augmentation should be done during the training phase. Sharpening is not typically a necessary pre-processing step for inpainting.

質問 # 45
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. Augment the fine-tuning dataset with synthesized video-text pairs generated by another model.
B. Use a lower learning rate during fine-tuning.
C. Adding a contrastive loss to the fine-tuning process.
D. Implement a reinforcement learning objective that rewards the model for generating videos that are semantically similar to the text prompts.
E. Freeze the weights of the video encoder during fine-tuning.

正解：E

解説：
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.

質問 # 46
A multimodal A1 model is designed to translate sign language videos into text. The model performs well on videos with clear hand gestures and lighting conditions but struggles with videos recorded in low light or with partial hand occlusions. Which of the following strategies would be MOST effective in improving the model's robustness to these challenging conditions?

A. Training the model on a smaller dataset.
B. Applying image enhancement techniques (e.g., contrast adjustment, noise reduction) to the video frames.
C. Increasing the size of the text vocabulary.
D. Using a simpler text encoder.
E. Reducing the frame rate of the input videos.

正解：B

解説：
Applying image enhancement techniques to the video frames can improve the visibility of hand gestures in low-light conditions and reduce the impact of noise, making the model more robust. Reducing the frame rate or training on a smaller dataset would likely decrease performance. Increasing the text vocabulary or using a simpler text encoder would not directly address the issue of poor video quality.

質問 # 47
You are fine-tuning a pre-trained Generative A1 model for a specific downstream task with limited dat a. The model starts to exhibit catastrophic forgetting of the original pre-trained knowledge. Which technique could mitigate this issue effectively?

A. Freezing the weights of earlier layers in the network
B. Increasing the learning rate significantly
C. Adding more data augmentation
D. Using a smaller batch size
E. Elastic Weight Consolidation (EWC)

正解：A、E

質問 # 48
You're developing a system that analyzes video footage and generates textual summaries of the events occurring in the video. Which of the following architectures would be the MOST appropriate starting point for this task?

A. A purely convolutional neural network (CNN) for image classification.
B. A support vector machine (SVM) for classification.
C. A generative adversarial network (GAN) for image generation.
D. A transformer-based encoder-decoder architecture, with the encoder processing video frames (e.g., using a 3D CNN) and the decoder generating text.
E. A long short-term memory (LSTM) network for time series forecasting.

正解：D

解説：
Transformer-based encoder-decoder architectures are well-suited for sequence-to-sequence tasks like video captioning. The encoder can process the video frames to extract features, and the decoder can generate the corresponding textual summary. A 3D CNN can be used to extract spatio-temporal features from the video.
