NVIDIA Generative AI Multimodal 認定 NCA-GENM 試験問題 (Q93-Q98):

質問 # 93
Which of the following regularization techniques is MOST effective for preventing overfitting in a multimodal deep learning model with a large number of parameters and complex interactions between different modalities?

A. Early Stopping
B. Batch Normalization
C. L2 regularization
D. Dropout
E. L1 regularization

正解：D

解説：
Dropout is particularly effective for preventing overfitting in deep neural networks with many parameters. It randomly drops out neurons during training, forcing the network to learn more robust features and reducing co-adaptation between neurons. L1 and L2 regularization can also help, but they might not be as effective as dropout for very deep and complex models. Batch Normalization primarily helps with training stability and speed, although it can also have a slight regularization effect. Early stopping prevents overfitting by stopping training when the performance on a validation set starts to degrade.

You're building a virtual assistant using NVIDIAAvatar Cloud Engine (ACE). You want the avatar to respond to user queries with realistic facial expressions and lip synchronization. Which ACE components are essential for achieving this?

A. Riva ASR, Riva TTS, Audi02Emotion, a 3D avatar model, and an animation engine.
B. Only a 3D avatar model.
C. only Riva ASR and TTS.
D. Riva ASR, Riva TTS, and Audi02Emotion.
E. Riva ASR, Riva TTS, Audi02Emotion, and a 3D avatar model.

正解：A

解説：
A complete ACE setup for realistic avatar interaction requires: Automatic Speech Recognition (ASR) to understand the user's query, Text-to-Speech (TTS) to generate the avatar's response, Audi02Emotion to infer emotional expressions from the text/audio, a 3D avatar model to represent the avatar visually, and an animation engine to drive facial expressions and lip synchronization. This combination ensures a lifelike and engaging user experience.

質問 # 95
Given the following Python code snippet utilizing spacy for text processing in a multimodal sentiment analysis pipeline, identify the potential issues and suggest improvements to enhance the accuracy and efficiency of the pipeline:

What improvements can be implemented?

A. The code doesn't account for the intensity of sentiment-bearing words. Introduce a weighting mechanism based on the part-of-speech tags to emphasize adjectives and adverbs.
B. The code calculates sentiment based on individual tokens, ignoring context and negations. Integrate a sentiment analysis library like VADER or TextBlob for more accurate sentiment scoring.
C. The code doesn't handle contractions or special characters. Implement preprocessing steps to normalize the text before processing it with spacy.
D. The code uses the small spacy model, which might not be accurate for sentiment analysis. Use a larger model like 'en_core_web_lg' for better performance.
E. Replace spacy entirely with NLTK for sentiment analysis, as it provides better pre-trained sentiment models.

正解：B、C、D

解説：
The small spacy model might lack the necessary vocabulary and training data for accurate sentiment analysis. The code's token- based sentiment calculation ignores context and negations, leading to inaccurate scoring. The code also needs preprocessing to handle contractions and special characters effectively. Sentiment analysis libraries provide more robust sentiment scoring mechanisms. Weighting by POS tags can help, but a better sentiment library is preferrable. Switching to NLTK entirely isn't necessarily better, upgrading the spacy model is a better option.

質問 # 96
Which of the following NVIDIA SDKs is most suitable for deploying a real-time, low-latency speech-to-text service as part of a multimodal AI application?

A. CUDA Toolkit
B. NVIDIA NeMo.
C. NVIDIA Riva
D. NVIDIA Tritone Inference Server
E. NVIDIAAvatar Cloud Engine (ACE)

正解：C

解説：
NVIDIA Riva is specifically designed for building and deploying real-time conversational A1 services, including speech-to-text, text-to- speech, and natural language understanding. Its focus is on low latency and high accuracy for conversational applications.

質問 # 97
Consider a multimodal dataset consisting of product reviews (text), product images, and customer demographics. You want to build a model that can predict customer satisfaction based on all three modalities. However, you suspect that there might be complex interactions between these modalities that are not easily captured by simple concatenation or averaging. What approach would be most effective for modeling these interactions?

A. Employing transfer learning, using pre-trained models for image and text processing then using the final combined layer for downstream task.
B. Training separate models for each modality and then averaging their predictions.
C. Using a gated recurrent unit (GRU) to process the combined data.
D. Using a tensor fusion network that explicitly models higher-order interactions between modalities.
E. Concatenating the feature vectors from each modality and feeding them into a single fully connected layer.

正解：A、D

解説：
Tensor fusion networks are designed to model complex, higher-order interactions between modalities. They create a tensor representation that captures all possible combinations of features from different modalities. This allows the model to learn intricate relationships that would be missed by simpler fusion techniques. Transfer learning is effective in scenarios where pre-trained models for image and text processing help boost the accuracy of final layer during downstream task.
