NVIDIA Generative AI Multimodal Sample Questions (Q18-Q23):

NEW QUESTION # 18
You are developing a multimodal system for medical diagnosis that integrates patient history (text), X-ray images, and heart rate data (time-series). A significant portion of the heart rate data is missing due to sensor failures. What is the MOST appropriate method to handle this missing data to ensure the model's accuracy and prevent bias?

A. Replace the missing heart rate data with the mean heart rate value calculated from the available data.
B. Assign a fixed, arbitrary value (e.g., 0) to all missing heart rate data points.
C. Train a separate model specifically on data without the time-series component.
D. Remove the records of patients with missing heart rate data from the dataset.
E. Use a time-series imputation technique, such as Kalman filtering or recurrent neural networks, to estimate the missing heart rate values based on the available data and temporal patterns.

Answer: E

Explanation:
Imputation using time-series techniques (C) is the most suitable method as it leverages the temporal dependencies within the heart rate data to estimate missing values, minimizing bias and preserving the integrity of the data. Mean imputation or arbitrary value assignment can introduce significant bias, and removing records reduces the dataset size.

NEW QUESTION # 19
Which of the following techniques can be used to improve the factual accuracy of text generated by a large language model?

A. Using retrieval-augmented generation (RAG) to ground the model's knowledge in external sources.
B. Fine-tuning the model on a dataset of factually correct information.
C. Increasing the model size and training it on more data.
D. Always using the same prompt, regardless of the desired output.
E. Applying a temperature of 0 during text generation.

Answer: A,B,C

Explanation:
Increasing model size and training data can improve factual accuracy, but it's not a guaranteed solution. Fine-tuning on factually correct data directly teaches the model to generate accurate information. RAG allows the model to access external knowledge sources and incorporate them into the generated text, which significantly improves factual accuracy. A temperature of 0 makes the model more deterministic but doesn't guarantee accuracy. Varying prompts is important for exploring the model's capabilities, but it doesn't directly address factual accuracy.

NEW QUESTION # 20
Which of the following techniques is LEAST likely to improve the performance of a Generative A1 model tasked with generating realistic images from text descriptions?

A. Increasing the size of the training dataset with high-quality image-text pairs.
B. Applying data augmentation techniques to the training images, such as random cropping and rotations.
C. Using a more powerful generative architecture, such as a Transformer-based diffusion model.
D. Reducing the dimensionality of the text embeddings used as input to the image generator.
E. Implementing classifier-free guidance during the diffusion process.

Answer: D

Explanation:
Reducing the dimensionality of text embeddings will likely degrade performance, as it removes information that the model needs to accurately generate images. The other options (A, B, C, and E) are all established techniques for improving the quality and fidelity of generated images.

NEW QUESTION # 21
You are building a multimodal RAG application that integrates text documents and images. You've noticed that when a user query relates strongly to the visual content, the retrieved documents are less relevant than desired. Which of the following strategies would MOST effectively improve the retrieval of relevant information in this scenario?

A. Fine-tune the existing text embedding model with more text data.
B. Increase the k value (number of retrieved documents) in the vector search.
C. Prepend the image captions to all the source documents to enhance text-based retrieval.
D. Use a larger language model for the generative component of the RAG pipeline.
E. Implement cross-modal embedding, training a model to create a joint embedding space for text and images.

Answer: E

Explanation:
Cross-modal embedding allows you to represent both text and images in a shared vector space. This enables the retrieval system to understand the relationship between text and visual content, leading to more relevant document retrieval when the query relates to images. Increasing 'k' might retrieve more irrelevant documents. A larger LLM and fine-tuning the text embedding model won't directly address the core issue of multimodal understanding.

NEW QUESTION # 22
Which of the following techniques are commonly used to address the 'hallucination' problem in generative A1 models, where the model generates content that is factually incorrect or nonsensical? (Select all that apply)

A. Increasing the model size and training dataset.
B. Implementing retrieval-augmented generation (RAG), where the model consults an external knowledge source before generating content.
C. Using Reinforcement Learning from Human Feedback (RLHF) to align the model's output with human preferences and factual correctness.
D. Lowering the temperature parameter during decoding to encourage more conservative and predictable outputs.
E. Employing adversarial training techniques to improve the model's robustness to noisy input data.

Answer: B,C,D

Explanation:
RLHF helps align the model with human values, reducing nonsensical outputs. RAG grounds the generation process in external knowledge, ensuring factual accuracy. Lowering the temperature reduces the likelihood of sampling low-probability, potentially hallucinated, tokens. Increasing model Size or using adversarial training can improve model performance, but doesn't directly address hallucination.
