NEW QUESTION # 129
You are designing an AI application that must handle multiple language tasks, such as translation, summarization, and text classification. During testing, you find that for certain specialized tasks, the model performs poorly without examples.
Which of the following statements best explains the differences in generalization between zero-shot and few-shot prompting, and how you might improve the model's performance? (Select two)
- A. Zero-shot prompting is ideal for tasks the model has been explicitly trained for, while few-shot prompting is best for tasks that the model has never encountered before.
- B. Zero-shot prompting leads to better generalization because the model doesn't rely on examples, forcing it to generate answers purely based on the pre-trained knowledge.
- C. Few-shot prompting enhances the model's generalization by providing the model with a variety of task-specific examples, allowing it to infer the pattern for unfamiliar tasks.
- D. Few-shot prompting is more effective than zero-shot prompting when the task requires more nuanced, context-dependent outputs, as it allows the model to learn from examples in real-time.
- E. Few-shot prompting typically degrades generalization as it encourages the model to overfit to the specific examples provided, whereas zero-shot prompting forces the model to maintain its general-purpose capabilities.
Answer: C,D
NEW QUESTION # 130
You are tasked with designing a Retrieval-Augmented Generation (RAG) system using embeddings to improve the response quality of a generative AI model.
In this context, what are embeddings used for, and how do they contribute to enhancing the generative AI's performance?
- A. Embeddings compress the input data to reduce computational load, improving the efficiency of the retrieval and generation process.
- B. Embeddings transform the input data into high-dimensional vectors, capturing semantic similarities between the input query and potential retrieval candidates to provide contextually relevant information for the generative model.
- C. Embeddings provide a summary of the input data, which the model then uses to generate its final output without retrieving external content.
- D. Embeddings serve as a form of knowledge storage within the generative model, allowing it to answer questions without retrieving external information.
Answer: B
