| Term | Definition |
|---|---|
| How are documents usually evaluated in the simplest form of keyword-based search? | ** Based on the presence and frequency of the user-provided keywords |
| When is fine-tuning an appropriate method for customizing a Large Language Model (LLM)? | When the LLM does not perform well on a task and the data for prompt engineering is too large |
| n which scenario is soft prompting appropriate compared to other training styles? | ** When there is a need to add learnable parameters to a Large Language Model (LLM) without task-specific training |
| How does the temperature setting in a decoding algorithm influence the probability distribution over the vocabulary? | ** Increasing the temperature flattens the distribution, allowing for more varied word choices. |
| Which statement is true about Fine-tuning and Parameter-Efficient Fine-Tuning (PEFT)? | ** Fine-tuning requires training the entire model on new data, often leading to substantial computational costs, whereas PEFT involves updating only a small subset of parameters, minimizing computational requirements and data needs. |
| What does accuracy measure in the context of fine-tuning results for a generative model? | ** How many predictions the model made correctly out of all the predictions in an evaluation |
| In the context of generating text with a Large Language Model (LLM), what does the process of greedy decoding entail? | * Choosing the word with the highest probability at each step of decoding |
| In the simplified workflow for managing and querying vector data, what is the role of indexing? | ** To map vectors to a data structure for faster searching, enabling efficient retrieval |
| When does a chain typically interact with memory in a run within the LangChain framework? | ** After user input but before chain execution, and again after core logic but before output |
| What do prompt templates use for templating in language model applications? | ** Python's str.format syntax |
| What does a cosine distance of 0 indicate about the relationship between two embeddings? | ** They are similar in direction |
| Which is a characteristic of T-Few fine-tuning for Large Language Models (LLMs)? It does not update any weights but restructures the model architecture. | ** It selectively updates only a fraction of the model's weights. |
