⚠️ Warning: "Optimism Bias" in Reinforcement Learning 🚨
When designing reinforcement learning algorithms, it's easy to overlook the "Optimism Bias," a pitfall that can significantly affect the performance and reliability of your model. This phenomenon occurs when an agent is overconfident in its ability to predict future rewards, leading to suboptimal exploration and exploitation strategies.
What is Optimism Bias?
In reinforcement learning, optimism bias arises from the agent's tendency to overestimate the rewards it expects to receive from a particular action or state. This overconfidence can lead to an agent favoring actions that seem most rewarding, even if they are not the most optimal. As a result, the agent may fail to explore alternative actions that could lead to better outcomes.
Consequences of Optimism Bias
Optimism bias can have several negative consequences, including:
- Suboptimal decision-making: Overconfident agents may make decisions that lead to p...
