최신 NVIDIA-Certified Associate NCA-GENM 무료샘플문제 (Q51-Q56):

질문 # 51
You are building a Generative Adversarial Network (GAN) to generate high-resolution images. The generated images suffer from mode collapse, where the generator only produces a limited variety of images. Which of the following techniques would be MOST effective in mitigating mode collapse?

A. Using a simpler generator architecture.
B. Decreasing the learning rate of the discriminator.
C. Reducing the size of the generator's latent space.
D. Increasing the learning rate of the generator.
E. Using mini-batch discrimination or feature matching in the discriminator.

정답：E

설명：
Mini-batch discrimination and feature matching encourage the generator to produce diverse images by considering the relationships between generated samples in a batch. Adjusting learning rates may have some effect but doesn't directly address the diversity issue. Reducing the latent space or using a simpler generator would likely reduce the generator's capacity and exacerbate mode collapse.

질문 # 52
Which of the following losses are suitable and can be used when training a Variational Autoencoder (VAE)?

A. Hinge Loss
B. KL Divergence Loss
C. Cross-entropy loss
D. Mean Squared Error (MSE) loss
E. Contrastive Loss

정답：B,C,D

설명：
VAEs typically use a combination of reconstruction loss (cross-entropy or MSE, depending on the data type) to ensure the decoder can accurately reconstruct the input, and KL divergence loss to enforce a prior distribution on the latent space. Hinge loss is commonly used in SVMs and contrastive loss is used in siamese networks to learn embeddings. Reconstruction loss based on Cross-entropy is used for descrete value as in binary classification, and MSE is used to capture how different each generated pixel from the corresponding pixel, which encourages the network to create accurate reconstruction.

질문 # 53
You are developing a multimodal model that combines time-series data from sensor readings with natural language descriptions of events. The time-series data has varying sampling rates and the text descriptions are often vague and ambiguous. How would you best address the challenge of aligning and fusing these two modalities to improve model performance?

A. Resample the time-series data to a uniform sampling rate and directly concatenate it with the text embeddings.
B. Use a dynamic time warping (DTW) algorithm to align the time-series data with the text descriptions and then use a cross-modal attention mechanism for fusion.
C. Train separate models for time-series and text and average their predictions.
D. Ignore the time-series data and train the model only on the text descriptions.
E. Average the time-series data over a fixed time window and concatenate it with the text embeddings.

정답：B

설명：
DTW helps align time-series data with varying lengths and temporal distortions to text. Cross-modal attention then effectively fuses the aligned modalities, allowing the model to learn relationships between them. Resampling and direct concatenation (A) doesn't account for temporal variations. Ignoring data (B) is counterproductive. Averaging (D) loses temporal information. Averaging separate model outputs (E) is a form of late fusion and less effective than joint learning after alignment.

질문 # 54
You are working on a Generative A1 project that involves analyzing text dat a. You've noticed that certain words are appearing much more frequently than others, potentially skewing your results. Which of the following techniques would be MOST effective in addressing this issue?

A. Removing all stop words and applying TF-IDF (Term Frequency-Inverse Document Frequency).
B. Stemming and lemmatization to reduce words to their root form.
C. Applying word embeddings to capture semantic meaning.
D. Converting all text to lowercase and removing punctuation.
E. Increasing the vocabulary size of the tokenizer.

정답：A

설명：
Removing stop words eliminates common words like 'the,' 'a,' 'is,' which often dominate text data. TF-IDF then weights words based on their frequency in a document relative to their frequency across all documents, reducing the impact of common words and highlighting important terms. Options B and C are helpful but not sufficient. Option D can actually worsen the issue. Option E addresses semantic meaning, not frequency imbalance.

질문 # 55
You're working on a multimodal AI system that combines text and image dat a. You're using a contrastive learning approach to learn joint embeddings of text and images. However, you notice that the system performs well on seen image-text pairs but poorly on unseen combinations. What technique MOST directly addresses this generalization problem?

A. Implementing hard negative mining.
B. Using a larger batch size during training.
C. Decreasing the temperature parameter in the contrastive loss.
D. Using a simpler model architecture-
E. Increasing the embedding dimension-

정답：A

설명：
Hard negative mining focuses on selecting the most challenging negative examples (incorrect image-text pairs) during training. This forces the model to learn more robust and discriminative embeddings that generalize better to unseen combinations. Increasing embedding dimension or using larger batch size might help to some extent, but hard negative mining directly addresses the core issue of distinguishing similar but incorrect pairs. Decreasing the temperature parameter can make the contrastive loss too sensitive, potentially hindering generalization. A simpler model architecture may be detrimental if it lacks the capacity to capture the complex relationships
