Question # 4

How does the Retrieval-Augmented Generation (RAG) Token technique differ from RAG Sequence when generating a model's response?

Options:

A.

Unlike RAG Sequence, RAG Token generates the entire response at once without considering individual parts.

B.

RAG Token does not use document retrieval but generates responses based on pre-existing knowledge only.

C.

RAG Token retrieves documents oar/at the beginning of the response generation and uses those for the entire content

D.

RAG Token retrieves relevant documents for each part of the response and constructs the answer incrementally.

What is the purpose of Retrieval Augmented Generation (RAG) in text generation?

Options:

A.

To retrieve text from an external source and present it without any modifications

B.

To store text in an external database without using it for generation

C.

To generate text based only on the model’s internal knowledge without external data

D.

To generate text using extra information obtained from an external data source

B.

It assigns a penalty to frequently occurring tokens to reduce repetitive text.

C.

It determines the maximum number of tokens the model can generate per response.

C.

How many predictions the model made correctly out of all the predictions in an evaluation

C.

It standardizes vector lengths for meaningful comparison using metrics such as Cosine Similarity.

D.

It ensures that all vectors represent keywords only.

B.

PEFT modifies all parameters and uses unlabeled, task-agnostic data.

C.

PEFT does not modify any parameters but uses soft prompting with unlabeled data. PEFT modifies

D.

PEFT parameters and b typically used when no training data exists.
