Explanation

Correct Answer: B) Embeddings and Retrieval-Augmented Generation (RAG)

Why this is correct:

1. Embeddings are used to convert text (like research papers) into numerical vectors that capture semantic meaning, enabling similarity searches.

2. Retrieval-Augmented Generation (RAG) is specifically designed for this use case:

   • Retrieval: Searches through uploaded documents (research papers) to find relevant information

   • Augmented Generation: Uses the retrieved information to generate accurate, context-aware responses

   • This prevents hallucinations and ensures responses are grounded in the actual research papers

Why other options are incorrect:

• A) Reinforcement Learning: Used for training models through reward-based feedback, not for document search and retrieval

• C) Few-shot prompting: Involves providing a few examples to guide model responses, but doesn't handle document search and retrieval

• D) Transfer Learning: Involves adapting pre-trained models to new tasks, but doesn't specifically address document search and information retrieval

Key AWS Bedrock Features for this use case:

• Knowledge Bases: Store and index documents (research papers)

• Embeddings: Convert text to vectors for semantic search

• RAG: Retrieve relevant content and generate responses based on that content

• Foundation Models: Use models like Claude or Llama for natural language understanding and generation
