질문 # 52
You have been given a dataset with missing values. What is the first step you should take with the data?
정답：A
설명：
Before deciding *how* to handle missing data, best practice requires understanding *why* it's missing - analyzing whether missingness is Missing Completely at Random (MCAR, no systematic pattern), Missing at Random (MAR, related to other observed variables but not the missing value itself), or Missing Not at Random (MNAR, related to the missing value itself, e.g., patients with severe symptoms being less likely to complete a survey field). This diagnostic step determines which downstream handling strategy is statistically appropriate: naive row deletion under MNAR conditions can introduce systematic bias into the remaining dataset, while mean/median imputation applied blindly can distort variance and correlational structure if missingness isn't actually random.
Options B, C, and D each jump directly to a specific remedial action without first establishing whether that action is appropriate for the missingness pattern present. Removing rows (B) sacrifices sample size and can bias results if missingness correlates with the outcome of interest. Filling with a default value (C) without understanding the pattern risks introducing artificial structure that doesn't reflect the true underlying data.
Removing entire columns (D) may discard genuinely informative features if missingness in that column is low or non-systematic.
Only after this initial pattern analysis should you select an appropriate strategy: listwise deletion, mean/median
/mode imputation, model-based imputation (e.g., MICE, k-NN imputation), or explicit missingness indicators as additional features.

질문 # 53
You are building a multimodal model that combines text and image data to generate captions. The text encoder is a pre-trained BERT model, and the image encoder is a ResNet-50. You observe that the generated captions are heavily biased towards descriptions based on the text input, and the image information is not well represented. Which of the following techniques could you apply to improve the contribution of the image modality?
정답：D
설명：
Applying a modality-specific loss weight allows you to explicitly control the importance of each modality during training. By increasing the weight of the image loss, you encourage the model to pay more attention to the image information and generate captions that are more representative of the visual content. Increasing BERT's learning rate could worsen the imbalance. PCA is a data reduction technique not a balancing technique, freezing the weights on resnet 50, will not allow the network to learn about the relationship, batch size is to do with training speed not modality balance.
질문 # 54
You are working on a project that involves generating realistic images from text descriptions using a diffusion model. You want to reduce the inference time of the model, which currently takes several minutes to generate a single image. Which of the following techniques would be MOST effective for accelerating inference without significantly compromising image quality?
정답：E
설명：
DDIM and progressive distillation are specifically designed to reduce the number of sampling steps needed in diffusion models, leading to faster inference. Increasing diffusion steps (A) would increase inference time. Smaller batch size (B) might reduce memory usage, but not significantly affect overall inference time. Training with a larger dataset (D) improves quality, but not inference speed. Switching to CPU (E) would dramatically slow down inference.
질문 # 55
What advantage does multimodal learning have over unimodal learning?
정답：B
설명：
Multimodal learning's principal advantage is access to complementary and, at times, redundant information across modalities that a single modality alone cannot provide - enabling the model to capture richer, more nuanced patterns and relationships. A sentiment analysis system that sees only text misses tone-of-voice cues available in audio and facial expression cues available in video; combining all three lets the model resolve ambiguity that any single modality would leave unresolved (sarcasm detected via mismatched text sentiment and vocal tone, for instance). This complementarity is the substantive, well-evidenced advantage of multimodal approaches in the research literature.
The other options overstate or misstate multimodal learning's properties: it does not inherently require fewer data samples (A) - in fact, multimodal models often require more data to learn reliable cross-modal correspondences, and can be more data-hungry in practice, particularly during pretraining. Reliability (C) is not an inherent, guaranteed property; multimodal systems introduce new failure modes, such as sensitivity to missing or corrupted modalities and to modality imbalance, that must be explicitly engineered against - reliability is not automatic. Multimodal data is also not inherently easier to collect (D); acquiring synchronized, aligned data across multiple modalities (e.g., paired audio-video-text with accurate timestamps) is typically harder and more resource-intensive than collecting a single modality.

질문 # 56
You're training a VQA (Visual Question Answering) model. During evaluation, you notice the model performs well on common object recognition tasks but struggles with questions requiring reasoning about object relationships or scene understanding. What are the MOST effective strategies to improve the model's performance on these complex reasoning tasks? (Choose two)
정답：A,D
설명：
More sophisticated attention mechanisms help the model focus on relevant image regions. A larger, more diverse dataset provides the model with more examples of complex reasoning scenarios. Increasing the image embedding size may help but is not as targeted. Decreasing the learning rate is a general optimization technique, and using a simpler RNN would likely degrade performance.
