NVIDIA Generative AI Multimodal 認定 NCA-GENM 試験問題 (Q80-Q85):

質問 # 80
You are developing a multimodal model that takes both images and text as input. You want to fuse these modalities at an early stage.
Which of the following techniques is MOST appropriate for early fusion?

A. Concatenating the raw image pixels and text tokens as a single input sequence.
B. Concatenating the feature vectors extracted from the image and text encoders before passing them to a shared decoder.
C. Passing the image and text through separate encoders and then using a late fusion technique such as a weighted sum of their outputs.
D. Using a cross-attention mechanism between the image and text feature maps in the early layers of the model.
E. Training separate models for images and text and then averaging their predictions.

正解：D

解説：
Cross-attention mechanisms at early layers allow the model to learn interactions between image and text features from the beginning, enabling a more nuanced understanding of their relationships. Concatenating feature vectors is a form of early fusion (A), but cross- attention is more powerful. Averaging predictions (B) is a late fusion technique. Concatenating raw pixels and tokens (E) is unlikely to work well due to the different nature of the data. Weighted sum (D) represents late fusion.

質問 # 81
You are building a multimodal model for medical image diagnosis, using both radiology images (e.g., X-rays) and patient clinical notes.
The clinical notes are highly unstructured and contain significant medical jargon. What preprocessing steps would be MOST effective for improving the model's performance?

A. Utilizing named entity recognition (NER) to identify medical entities (diseases, medications, etc.), and employing a medical-specific language model (e.g., BioBERT) for text embeddings.
B. Applying basic text cleaning (removing punctuation, converting to lowercase) and using a standard word embedding (e.g., Word2Vec).
C. Directly feeding the raw clinical notes into the model without any preprocessing.
D. Performing sentiment analysis on the clinical notes.
E. Translating the clinical notes into multiple languages and then back-translating to the original language.

正解：A

解説：
For medical text, NER and BioBERT are the best choice. NER extracts relevant medical information, while BioBERT is pre-trained on a large corpus of biomedical text, allowing it to better understand medical jargon and context. Raw text (A) would be ineffective. Basic cleaning and Word2Vec (B) are insufficient for complex medical language. Translation (D) isn't the primary preprocessing step needed. Sentiment analysis (E) is You have a multimodal generative model that produces images from text descriptions.

質問 # 82
You are training a multimodal generative A1 model that takes text and images as input to generate videos. During experimentation, you observe that the model performs well on common scenarios (e.g., 'a dog playing in the park') but struggles to generate coherent videos for less frequent or abstract scenarios (e.g., 'the concept of time flowing'). What is the MOST effective strategy to improve the model's performance on these challenging scenarios, focusing on test data quality?

A. Implement data augmentation techniques on the existing training data, focusing on color adjustments and minor image transformations.
B. Train the model for a significantly longer duration on the existing training data.
C. Increase the size of the training dataset by duplicating existing common scenario examples.
D. Curate a new test dataset specifically containing challenging scenarios and use it to evaluate and fine-tune the model. Ensure the new test data includes diverse interpretations and variations of the abstract concepts.
E. Reduce the complexity of the model architecture to prevent overfitting on the common scenarios.

正解：D

解説：
Curating a specific test dataset for challenging scenarios allows for targeted evaluation and fine-tuning. Duplicating common scenarios (A) won't address the problem. Simple augmentations (B) may not be sufficient. Reducing model complexity (D) might hurt overall performance. Longer training (E) without addressing data bias is unlikely to help significantly.

質問 # 83
You are building a multimodal model to predict stock prices using financial news articles (text), historical stock prices (time-series), and company logos (images). You have preprocessed the data and are ready to train your model. Which of the following architectures would be MOST suitable for effectively integrating these three modalities?

A. A model that converts all data into a single text format and uses a large language model (LLM) for prediction.
B. A model that uses a Transformer encoder for each modality, followed by a shared Transformer decoder for prediction, enabling cross-modal attention at the decoder level.
C. A model that combines a Transformer for text, an LSTM for time-series, and a CNN for images, with a late fusion strategy using a weighted averaging of predictions.
D. A simple feed forward neural network with concatenated features from all modalities.
E. Separate models for each modality trained independently, and then ensembled together at the prediction stage.

正解：B、C

解説：
Combining a Transformer for text, an LSTM for time-series, and a CNN for images with a late fusion approach allows each modality to be processed by a suitable architecture and then combined to generate a final prediction. Using transformers in each modality with shared Transformer decoder can efficiently integrate and predict stock prices using cross modal attention . A simple feedforward network is unlikely to capture the temporal dependencies in the time-series data or the complex relationships between modalities. Ensembling independent models doesn't allow for cross-modal learning. Converting all data into text might lose valuable information from the other modalities. Therefore, hybrid architecture combining transformers, LSTMs, and CNNs with cross-modal attention or late fusion would be most effective.

質問 # 84
Consider the following Python code snippet used for processing image and text data for a multimodal model:

What is the primary limitation of the text encoding method used in this code, and how could it be improved for use in a real-world multimodal model?

A. The text encoding is efficient but incompatible with common deep learning architectures.
B. The text encoding only supports ASCII characters and does not account for word embeddings or sequence length variations. Use a tokenizer like BERT or SentencePiece to generate embeddings and pad sequences to a fixed length
C. The text encoding is overly complex and should be simplified to reduce computational overhead.
D. It adequately addresses the complexities inherent in natural language, making it suitable for a variety of multimodal models.
E. The text encoding is suitable for small datasets but will not scale to larger datasets.

正解：B

解説：
The code simply converts each character to its ASCII value, which loses semantic meaning and doesn't handle variable-length sequences or word relationships. Real-world models use tokenizers and embeddings to capture the nuances of language. BERT and SentencePiece are common tools for this. Option B accurately describes this limitation and suggests a practical solution.
