Study Notes
Keyword-Based Document Evaluation
- Documents are primarily evaluated based on the presence and frequency of user-provided keywords.
Fine-Tuning Large Language Models (LLM)
- Fine-tuning is suitable when the LLM does not perform well on a task and when data for prompt engineering is too vast.
- It allows the model to access the latest data for improved output generation.
Soft Prompting
- Soft prompting is advantageous when adapting a model to perform in a new domain not covered in its original training.
- It adds learnable parameters to a LLM without requiring task-specific training.
Temperature Setting in Decoding Algorithms
- Increasing temperature flattens the probability distribution, promoting more diverse word choices.
- Decreasing temperature narrows the distribution, favoring more likely words.
Fine-tuning vs. Parameter-Efficient Fine-Tuning (PEFT)
- Fine-tuning involves training the entire model on new data, leading to high computational costs.
- PEFT updates only a small subset of parameters, thus minimizing data requirements and computational load.
Accuracy Measurement in Generative Models
- Accuracy reflects the proportion of correct predictions made by the model during evaluation.
Greedy Decoding in Text Generation
- Greedy decoding involves selecting the word with the highest probability at each decoding step.
Indexing in Vector Data Management
- Indexing maps vectors to a data structure, allowing for rapid searching and efficient retrieval.
Memory Interaction in LangChain Framework
- A chain interacts with memory after user input but before chain execution and again after core logic before producing output.
