질문 # 53
Consider a scenario where you are evaluating the performance of a multimodal A1 model that generates descriptions for images. However, the generated descriptions tend to be repetitive and lack diversity. Which of the following techniques can be employed to address this issue and encourage more diverse and creative outputs from the model? (Select TWO)

A. Employing a nucleus sampling (top-p sampling) decoding strategy.
B. Utilizing a temperature scaling parameter during decoding and increasing its value.
C. Using a beam search decoding strategy with a small beam width.
D. Using a greedy decoding strategy.
E. Increasing the model's training data size.

정답：A,B

설명：
Nucleus sampling (top-p sampling) randomly samples from the smallest set of words whose cumulative probability mass exceeds a threshold p, encouraging more diverse outputs. Increasing the temperature scaling parameter makes the probability distribution flatter, leading to more exploration and less predictable (more creative) outputs. Beam search with a small beam width might still result in repetitive outputs. Increasing the training data size can help, but it might not directly address the lack of diversity. Greedy decoding always selects the most probable word, leading to repetitive and predictable outputs.

질문 # 54
You are analyzing a dataset of customer reviews for a Generative A1-powered product. You want to identify the key themes and topics that customers are discussing. Which technique would be MOST appropriate for this task?

A. Time series analysis to track review volume over time.
B. Clustering analysis to group customers based on demographics.
C. Topic modeling (e.g., LDA, NMF) to discover underlying themes in the reviews.
D. Sentiment analysis to determine the overall positive or negative sentiment.
E. Regression analysis to predict customer satisfaction scores.

정답：C

설명：
Topic modeling is specifically designed to discover the underlying themes and topics within a collection of documents (in this case, customer reviews). LDA (Latent Dirichlet Allocation) and NMF (Non-negative Matrix Factorization) are common topic modeling techniques. Sentiment analysis provides an overall sentiment score but doesn't identify specific themes. Regression analysis is for prediction, not theme discovery. Clustering groups customers, not review topics. Time series analysis tracks changes over time, not themes.

질문 # 55
You are building a multimodal generative model that combines text and images. The goal is to generate realistic images based on textual descriptions. You have access to a pre-trained language model (e.g., BERT) and a pre-trained image generation model (e.g., StyleGAN). Which of the following architectures would be MOST suitable for effectively integrating these two models to achieve your objective?

A. Concatenating the text and image data into a single vector and feeding it into a standard feedforward neural network.
B. Training a separate neural network to map the image to the text description.
C. Fine-tuning the language model to directly output pixel values for the image.
D. Using the language model to generate captions for the images, and then training the image generation model on the captions.
E. Using the language model to generate a latent vector that is then fed into the image generation model as input.

정답：E

설명：
Using the language model to generate a latent vector that serves as input to the image generation model is an effective approach for multimodal integration. This allows the language model to encode the textual description into a meaningful representation that can guide the image generation process. Fine-tuning the language model to output pixel values directly is not feasible due to the high dimensionality of images. Training a separate network to map images to text is a reverse task. Concatenating text and image data may not effectively capture the complex relationships between modalities. Generating captions for images is not the primary objective.

질문 # 56
You're working on a project involving multimodal transfer learning for generating recipes from images of dishes and ingredient lists. You have a large dataset of images but a limited dataset of paired images and ingredient lists. You decide to leverage a pre-trained image model and a pre-trained text model. However, you are facing catastrophic forgetting after fine-tuning the models on the paired image and ingredient list dat a. Which of the following techniques would be MOST effective in mitigating catastrophic forgetting while adapting the pre-trained models to the new task?

A. Freeze the weights of the pre-trained models and only train a small adapter module that bridges the gap between the pre-trained features and the recipe generation task.
B. Apply L1 regularization to the model weights.
C. Increase the batch size during fine-tuning.
D. Use a very high learning rate during fine-tuning.
E. Train the entire model from scratch on the limited paired dataset.

정답：A

설명：
Using adapter modules is a common technique to mitigate catastrophic forgetting. By freezing most of the pre-trained weights and only training a small adapter, you preserve the knowledge learned during pre-training while adapting the model to the new task. Training from scratch would negate the benefits of transfer learning. A high learning rate can exacerbate forgetting. L1 regularization can prevent overfitting but doesn't directly address forgetting. Increasing batch size might improve generalization but doesn't solve the core issue of catastrophic forgetting.

질문 # 57
You're building a system to translate customer service chat logs into summaries that a human agent can quickly review The chat logs are often informal, contain slang, and have grammatical errors. Which prompt engineering technique is MOST likely to improve the quality and accuracy of the summaries generated by a large language model (LLM)?

A. Using a template prompt with predefined sections and keywords to guide the summarization process and ensure consistency across different chat logs.
B. Using a few-shot prompt with several examples of chat logs and their ideal summaries, explicitly demonstrating how to handle informality and errors.
C. Using a zero-shot prompt with a simple instruction like 'Summarize this chat log.'
D. Using chain-of-thought prompting to encourage the LLM to explain its reasoning process before generating the summary.
E. Using a negative constraint prompt, explicitly stating what the LLM should not include in the summary (e.g., 'Do not include greetings or farewells.').

정답：A,B,D,E

설명：
Few-shot prompting provides the LLM with examples to learn from, allowing it to better handle the nuances of informal language and errors. Chain-of-thought helps the model reason step-by-step, leading to better summaries. Negative constraints prevent irrelevant information. Template prompts provide structure and consistency. A zero-shot prompt is less effective in this scenario due to the complexity of the input data.
