Reinforcement Learning Task

A Reinforcement Learning Task is an online reward-maximization task that requires the use of a reinforcement learning algorithm (which involves an agent learning to make decisions through trial and error, aiming to maximize cumulative rewards over time by interacting with a dynamic environment).

• Context:
  • It often involves the challenge of the Exploration/Exploitation Tradeoff, requiring the agent to balance between exploring the environment to find new strategies and exploiting known strategies for maximum reward.
  • It can range from being a Discreate-Space Reinforcement Learning Task to being a Continuous-Space Reinforcement Learning Task.
  • …
• Example(s):
  • an RL-based Autonomous Helicopter Flight Task, as presented in the paper "Robust Deep Reinforcement Learning for Quadcopter Control".
  • a RL-based Robot Control Task, as detailed in "Adaptive Gain Scheduling using Reinforcement Learning for Quadcopter Control".
  • a RL-based Game Playing Task, ...
  • an RL-based Autonomous System Task, ...
  • an RL-based Adaptive User Interface Task, ...
  • a RL-based Dynamic Item Recommendation Task, ...
  • a RL-based Real-Time Traffic Light Control Task, ...
  • a RL-based Personalized Healthcare Decision Support Task, ...
  • an RL-based Adaptive Energy Management Task, ...
  • …
• Counter-Example(s):
  • A Linear Regression task, where the goal is to fit a linear model to a dataset without any interactive decision-making process.
  • A Clustering Task, which involves grouping a set of objects in such a way that objects in the same group are more similar to each other than to those in other groups, without the use of rewards or interactive environments.
