SAMPLE QUESTION:
Which of the following are valid model customization methods for Amazon Bedrock? (Select two)
1. Continued Pre-training
2. Fine-tuning
3. Retrieval Augmented Generation (RAG)
4. Zero-shot prompting
5. Chain-of-thought prompting
What’s your guess? Scroll below for the answer.
Correct: 1,2
Explanation:
Correct options:
Model customization involves further training and changing the weights of the model to enhance its performance. You can use continued pre-training or fine-tuning for model customization in Amazon Bedrock.
Continued Pre-training
In the continued pre-training process, you provide unlabeled data to pre-train a foundation model by familiarizing it with certain types of inputs. You can provide data from specific topics to expose a model to those areas. The Continued Pre-training process will tweak the model parameters to accommodate the input data and improve its domain knowledge.
For example, you can train a model with private data, such as business documents, that are not publicly available for training large language models. Additionally, you can continue to improve the model by retraining the model with more unlabeled data as it becomes available.
Fine-tuning
While fine-tuning a model, you provide labeled data to train a model to improve performance on specific tasks. By providing a training dataset of labeled examples, the model learns to associate what types of outputs should be generated for certain types of inputs. The model parameters are adjusted in the process and the model’s performance is improved for the tasks represented by the training dataset.
Incorrect options:
Retrieval Augmented Generation (RAG)
Retrieval Augmented Generation (RAG) allows you to customize a model’s responses when you want the model to consider new knowledge or up-to-date information. When your data changes frequently, like inventory or pricing, it’s not practical to fine-tune and update the model while it’s serving user queries. To equip the FM with up-to-date proprietary information, organizations turn to RAG, a technique that involves fetching data from company data sources and enriching the prompt with that data to deliver more relevant and accurate responses. RAG is not a model customization method.
Zero-shot prompting
Chain-of-thought prompting
Prompt engineering is the practice of carefully designing prompts to efficiently tap into the capabilities of FMs. It involves the use of prompts, which are short pieces of text that guide the model to generate more accurate and relevant responses. With prompt engineering, you can improve the performance of FMs and make them more effective for a variety of applications. Prompt engineering has techniques such as zero-shot and few-shot prompting, which rapidly adapts FMs to new tasks with just a few examples, and chain-of-thought prompting, which breaks down complex reasoning into intermediate steps.
Prompt engineering is not a model customization method. Therefore, both these options are incorrect.
