NVIDIA Generative AI Multimodal 認定 NCA-GENM 試験問題:

1. You are building a multimodal emotion recognition system that takes both facial expressions (images) and speech audio as input. During development, you observe that the model is heavily biased towards the audio modality, effectively ignoring the visual input. Which technique would be the LEAST effective in mitigating this modality bias?

A) Modality dropout: Randomly dropping out one of the modalities during training.
B) Increasing the complexity of the audio processing branch and simplifying the image processing branch of the model.
C) Adversarial training to make each modality indistinguishable.
D) Gradient blending: Adjusting the gradients from each modality based on their relative importance.
E) Reweighting the loss function to penalize errors made based on the less dominant modality (image).

2. You are tasked with optimizing a Generative A1 model that processes both image and text dat a. The current model uses a simple concatenation of image features (extracted from a ResNet-50) and text embeddings (from BERT) as input to a transformer. You observe that the model struggles to generate coherent descriptions for complex images. Which of the following optimization strategies would be MOST effective in improving the model's understanding of the multimodal input?

A) Augment the text data with more examples.
B) Reduce the learning rate by a factor of 10.
C) Increase the size of the transformer encoder layers.
D) Switch to a larger ResNet architecture (e.g., ResNet-101 ) while keeping the concatenation.
E) Replace concatenation with a cross-attention mechanism between image features and text embeddings.

3. You are building an A1 model that takes video and corresponding subtitles as input to generate short summaries of video content. Which of the following strategies are most important to reduce the chance of your model generating biased summaries? (Select all that apply)

A) Randomly shuffle data during training.
B) Increase the number of training epochs.
C) Evaluate the model's summaries on different demographic groups to identify and mitigate any disparities in performance.
D) Use a pre-trained language model that has been debiased.
E) Ensure the training dataset contains diverse representation of all demographic groups and viewpoints.

4. You are tasked with creating a multimodal A1 assistant that can understand and respond to user queries based on images and text. The assistant should be able to identify objects in images, understand the relationships between them, and answer questions about the image content using natural language. Given a scenario where a user uploads an image of a living room and asks, 'What is the color of the sofa next to the window?', what are the essential steps and techniques needed to implement this functionality?

A) Relationship extraction: Use a relationship extraction model to determine the spatial relationships between the detected objects (e.g., 'sofa is next to window').
B) Sentiment Analysis.
C) Object detection: Use an object detection model (e.g., YOLO, Faster R-CNN) to identify objects in the image (sofa, window, etc.).
D) Visual question answering (VQA): Use a VQA model that takes the image and the user's question as input and generates a natural language answer (e.g., 'The sofa is blue').
E) All of the above.

5. When training a multimodal model with both text and image data, what is a common challenge related to the different characteristics and scales of these modalities, and what are some common strategies to address it? (Select TWO correct answers)

A) Modalities often have different scales and distributions, leading to one modality dominating the learning process.
B) Always training the image processing part first and freezing the weights before text processing
C) Text data inherently contains more information than image data, making it difficult to balance their contributions.
D) Images are always processed faster than text, requiring artificial delays in the text processing pipeline.
E) Using modality-specific normalization techniques and carefully weighting the loss contributions from each modality.
