"# Learned Prompt Variable Injection via RL\n",
|
|
"\n",
|
|
"LLM prompts can be enhanced by injecting specific terms into template sentences. Selecting the right terms is crucial for obtaining high-quality responses. This notebook introduces automated prompt engineering through term injection using Reinforcement Learning with VowpalWabbit.\n",
|
|
"\n",
|
|
"The rl_chain (reinforcement learning chain) provides a way to automatically determine the best terms to inject without the need for fine-tuning the underlying foundational model.\n",
|
|
"\n",
|
|
"For illustration, consider the scenario of a meal delivery service. We use LangChain to ask customers, like Tom, about their dietary preferences and recommend suitable meals from our extensive menu. The rl_chain selects a meal based on user preferences, injects it into a prompt template, and forwards the prompt to an LLM. The LLM's response, which is a personalized recommendation, is then returned to the user.\n",

"\n",

"1. Accept the list of meals.\n",

"2. Consider the user and their dietary preferences.\n",

"6. Return the LLM's response to the user.\n",

|
|
"\n",
|
|
"Initially, since the RL model is untrained, it might opt for random selections that don't necessarily align with a user's preferences. However, as it gains more exposure to the user's choices and feedback, it should start to make better selections (or quickly learn a good one and just pick that!).\n"

|

"The general advice is to keep the score between [0, 1], 0 being the worst selection, 1 being the best selection from the available `ToSelectFrom` variables, based on the `BasedOn` variables, but should be adjusted if the need arises.\n",
