With traditional reinforcement learning, the goal is to find the best behavior or action to maximize reward in a given situation. When reading up on artificial neural networks, you may have come across the term “bias.” It’s sometimes just referred to as bias. This isn’t always a bad thing. Reinforcement learning vs inverse reinforcement learning . These inductive biases can take many forms, including domain knowledge and pretuned hyper-parameters. Many deep reinforcement learning algorithms contain inductive biases that sculpt the agent's objective and its interface to the environment. Reinforcement learning is a subfield within control theory, which concerns controlling systems that change over time and broadly includes applications such as self-driving cars, robotics, and bots for games. However, this low level reinforcement-learning bias may represent a computational building block for higher level cognitive biases such as belief perseverance, that is, the phenomenon that beliefs are remarkably resilient in the face of empirical challenges that logically contradict them [46,47]. In Richard S. Sutton and Andrew G. Barto's book on reinforcement learning on page 156 it says: Maximization bias occurs when estimate the value function while taking max on it (that is what Q learning do), and maximization may not take on the true value which may introduce bias. A high bias means the prediction will be inaccurate. Intuitively, bias can be thought as having a ‘bias’ towards people. Bias is the accuracy of our predictions. In general, there is a trade-off between generality and performance when algorithms use such biases. We’re going to break this bias down and see what it’s all about. Other times you may see it referenced as bias nodes, bias neurons, or bias units within a neural network. Throughout this guide, you will use reinforcement learning … If you are highly biased, you are more likely to make wrong assumptions about them. An oversimplified mindset creates an unjust dynamic: you label them accordingly to a ‘bias.’ 1.2 Implicit Bias, Reinforcement Learning, and Scaffolded Moral Cognition Bryce Huebner Recent data from the cognitive and behavioral sciences suggest that irrelevant features of our environment can often play a role in shaping our morally significant decisions.
