Learning and adaptation in agentic LLM systems

To enable our agent to learn and adapt from its experiences, let’s implement a simple reinforcement learning mechanism. This will allow the agent to improve its performance over time by learning from the outcomes of its actions.

We define the AdaptiveLearningAgent class, which extends StrategicDecisionAgent by introducing a simple Q-learning mechanism. It keeps track of q_values, which represents the expected rewards for taking specific actions in given states. The agent uses a learning rate to update these values based on new experiences:

import random
from collections import defaultdict
class AdaptiveLearningAgent(StrategicDecisionAgent):
    def __init__(self, llm, action_space: List[str], embedding_model):
        super().__init__(llm, action_space, embedding_model)
        self.q_values = defaultdict(lambda: defaultdict...
