Retrieval-Based Methods as a Solution for Long-Context Processing
To overcome the difficulty of training Transformers on very long sequences, non-parametric approaches like retrieval-based methods can be used. These methods leverage an external memory, such as a vector database of key-value pairs, to represent the context, thereby avoiding the need to process the entire long context directly within the Transformer architecture.

A company is building a question-answering system to help employees query a massive, static knowledge base of over 100,000 internal documents. The core language model has a fixed input size that is much smaller than the total size of the knowledge base. Which approach is the most effective and scalable for ensuring the model can access the necessary information to answer specific user queries accurately?

A company is developing a chatbot to provide real-time support by referencing its entire, multi-thousand-page library of technical documentation, which is updated daily. The language model powering the chatbot has a fixed, limited input size and cannot process the entire library at once. Which of the following approaches provides the most effective and scalable solution for this specific challenge?
A language model system is designed to answer questions using a vast library of documents that is too large to fit into the model's direct input. To manage this, it uses a retrieval-based approach with an external memory. Arrange the following actions into the correct operational sequence, from receiving a user's question to generating a final answer.
