NVIDIA Generative AI LLMs Sample Questions (Q37-Q42):

NEW QUESTION # 37
Which principle of Trustworthy AI primarily concerns the ethical implications of AI's impact on society and includes considerations for both potential misuse and unintended consequences?

A. Certification
B. Data Privacy
C. Legal Responsibility
D. Accountability

Answer: D

Explanation:
Accountability is a core principle of Trustworthy AI that addresses the ethical implications of AI's societal impact, including potential misuse and unintended consequences. NVIDIA's guidelines on Trustworthy AI, as outlined in their AI ethics framework, emphasize accountability as ensuring that AI systems are transparent, responsible, and answerable for their outcomes. This includes mitigating risks of bias, ensuring fairness, and addressing unintended societal impacts. Option A (Certification) refers to compliance processes, not ethical implications. Option B (Data Privacy) focuses on protecting user data, not broader societal impact. Option D (Legal Responsibility) is related but narrower, focusing on liability rather than ethical considerations.

NEW QUESTION # 38
How does A/B testing contribute to the optimization of deep learning models' performance and effectiveness in real-world applications? (Pick the 2 correct responses)

A. A/B testing allows for the comparison of different model configurations or hyperparameters to identify the most effective setup for improved performance.
B. A/B testing is irrelevant in deep learning as it only applies to traditional statistical analysis and not complex neural network models.
C. A/B testing helps validate the impact of changes or updates to deep learning models bystatistically analyzing the outcomes of different versions to make informed decisions for model optimization.
D. A/B testing guarantees immediate performance improvements in deep learning models without the need for further analysis or experimentation.
E. A/B testing in deep learning models is primarily used for selecting the best training dataset without requiring a model architecture or parameters.

Answer: A,C

Explanation:
A/B testing is a controlled experimentation technique used to compare two versions of a system to determine which performs better. In the context of deep learning, NVIDIA's documentation on model optimization and deployment (e.g., Triton Inference Server) highlights its use in evaluating model performance:
* Option A: A/B testing validates changes (e.g., model updates or new features) by statistically comparing outcomes (e.g., accuracy or user engagement), enabling data-driven optimization decisions.

NEW QUESTION # 39
In the context of fine-tuning LLMs, which of the following metrics is most commonly used to assess the performance of a fine-tuned model?

A. Training duration
B. Model size
C. Accuracy on a validation set
D. Number of layers

Answer: C

Explanation:
When fine-tuning large language models (LLMs), the primary goal is to improve the model's performance on a specific task. The most common metric for assessing this performance is accuracy on a validation set, as it directly measures how well the model generalizes to unseen data. NVIDIA's NeMo framework documentation for fine-tuning LLMs emphasizes the use of validation metrics such as accuracy, F1 score, or task-specific metrics (e.g., BLEU for translation) to evaluate model performance during and after fine-tuning.
These metrics provide a quantitative measure of the model's effectiveness on the target task. Options A, C, and D (model size, training duration, and number of layers) are not performance metrics; they are either architectural characteristics or training parameters that do not directly reflect the model's effectiveness.

NEW QUESTION # 40
Which of the following best describes the purpose of attention mechanisms in transformer models?

A. To generate random noise for improved model robustness.
B. To convert text into numerical representations.
C. To compress the input sequence for faster processing.
D. To focus on relevant parts of the input sequence for use in the downstream task.

Answer: D

Explanation:
Attention mechanisms in transformer models, as introduced in "Attention is All You Need" (Vaswani et al.,
2017), allow the model to focus on relevant parts of the input sequence by assigning higher weights to important tokens during processing. NVIDIA's NeMo documentation explains that self-attention enables transformers to capture long-range dependencies and contextual relationships, making them effective for tasks like language modeling and translation. Option B is incorrect, as attention does not compress sequences but processes them fully. Option C is false, as attention is not about generating noise. Option D refers to embeddings, not attention.

NEW QUESTION # 41
In neural networks, the vanishing gradient problem refers to what problem or issue?

A. The problem of underfitting in neural networks, where the model fails to capture the underlying patterns in the data.
B. The issue of gradients becoming too small during backpropagation, resulting in slow convergence or stagnation of the training process.
C. The problem of overfitting in neural networks, where the model performs well on the trainingdata but poorly on new, unseen data.
D. The issue of gradients becoming too large during backpropagation, leading to unstable training.

Answer: B

Explanation:
The vanishing gradient problem occurs in deep neural networks when gradients become too small during backpropagation, causing slow convergence or stagnation in training, particularly in deeper layers. NVIDIA's documentation on deep learning fundamentals, such as in CUDA and cuDNN guides, explains that this issue is common in architectures like RNNs or deep feedforward networks with certain activation functions (e.g., sigmoid). Techniques like ReLU activation, batch normalization, or residual connections (used in transformers) mitigate this problem. Option A (overfitting) is unrelated to gradients. Option B describes the exploding gradient problem, not vanishing gradients. Option C (underfitting) is a performance issue, not a gradient-related problem.
