摘要:

在过去的十年里,人工智能和光子技术取得了前所未有的增长,这两者都推动了现代计算设备的极限。根据这些最新的发展,这项工作在强化学习的框架内汇集了这两个领域的最新技术。我们提出了一个积极的学习机结合当代算法,如SARSA,Q-学习和投影模拟的光子实现的蓝图。我们在典型的强化学习环境中对其性能进行了数值研究,表明现实水平的实验噪声是可以容忍的,甚至对学习过程有益。值得注意的是,该架构本身支持抽象和泛化机制,这两个特性通常被认为是人工智能的关键要素。所提出的架构,基于单光子进化的可调分束器的网格,是简单的,可扩展的,第一次集成在便携式系统似乎是在短期内的技术范围内。

英文摘要:

The last decade has seen an unprecedented growth in artificial intelligence and photonic technologies, both of which drive the limits of modern-day computing devices. In line with these recent developments, this work brings together the state of the art of both fields within the framework of reinforcement learning. We present the blueprint for a photonic implementation of an active learning machine incorporating contemporary algorithms such as SARSA, Q-learning, and projective simulation. We numerically investigate its performance within typical reinforcement learning environments, showing that realistic levels of experimental noise can be tolerated or even be beneficial for the learning process. Remarkably, the architecture itself enables mechanisms of abstraction and generalization, two features which are often considered key ingredients for artificial intelligence. The proposed architecture, based on single-photon evolution on a mesh of tunable beamsplitters, is simple, scalable, and a first integration in portable systems appears to be within the reach of near-term technology.
