报告简介：
Reinforcement Learning (RL), one of the model free techniques, has been widely employed in recent years to solve complex engineering and non-engineering problems including self-driving cars, industry automation in production lines, financial trading, and healthcare with proven satisfactory solutions. Nevertheless, when problems/systems are more complex, the action and state-space can increase exponentially, and most RL techniques would fail to efficiently compute optimal policies to these problems leading to excessive computational overheads. It remains a challenge for RL techniques to balance between exploitation and exploration in larger spaces to efficiently (in terms of the speed of convergence/sample efficiency) optimise the RL model policy for best cumulated rewards. Quantum computation offers certain computational advantages with potential improvements to traditional RL models. Quantum Variational Circuit (QVC) provides computational advantage by using parameterized circuit running in quantum environment and output the parameter to classical optimizer. This talk covers the recent work of the presenter’s team which compares the performances of one qubit quantum enhanced RL models through structure variations including gates and trainable parameters using OpenAI Gym CarPole motion control platform. Through varying the structure, better CarPole motion control performances are obtained and discussed.
