Addressing LLM Knowledge Limitations with RAG
A company has built a customer support chatbot using a large language model. They notice that while the chatbot is excellent at general conversation, it frequently provides inaccurate information about product specifications that were updated last month, after the model's training data was finalized. Which of the following approaches best describes a method to ground the model's responses in the most current, verifiable information for each user query?
A user submits a query to a system designed to provide factually accurate answers by dynamically incorporating external knowledge. Arrange the following steps to correctly represent the operational flow of this system.

Inference Architecture of k-NN Language Models
Next-Token Prediction with External Memory
A language model is enhanced by searching a large datastore of past internal states and their corresponding next words. When the model generates a new word, it finds the 'k' most similar past states from the datastore and uses their associated next words to adjust its prediction. What is the key principle that makes this technique effective?
Foundational Principle of k-NN Language Modeling
A language model is designed to improve its next-word predictions by consulting a large external database of past contexts. Arrange the following steps to accurately describe how this model generates its final output after receiving an input.
A language model is designed to enhance its next-token prediction by referencing a large external datastore of context representations and their corresponding subsequent tokens. During generation, for a given input, the model identifies the 'k' most similar context representations from this datastore. Which of the following best describes how this information is integrated to produce the final prediction?

Pre-indexing k-NN Datastores for Efficient Retrieval
An e-commerce company has converted its catalog of 10 million product descriptions into high-dimensional numerical vectors. They want to build a search feature where a user's text query is also converted into a vector, and the system must rapidly return the top 10 products with the most similar description vectors. Which data storage solution is best suited for this specific task?

Implementing RAG Retrieval with Vector Databases
An automated system is designed to answer user questions. Its first step is to search a large document library to find the most relevant texts related to the user's query. The system will then use only these retrieved texts to generate a final answer. A user asks: 'What are the primary health benefits of a Mediterranean diet?' Which of the following sets of retrieved documents would be the most effective for the system's next step?
