Description

The arrival of cognitive computing has provided the networking community with a new design dimension to meet the exponentially increasing needs of data traffic. The essence is to allow networks and communication systems to adapt their settings by learning from operating environment. In this project, we focus on both algorithm design and system implementation by applying online learning to different networking problems.

Many problems in the context of cognitive computing filed, such as dynamic multi-channel access, can be formulated as a Partially Observable Markov Decision Problem (POMDP) (with known or unknown system dynamics) that is PSAPCE-hard. To overcome the challenge of computationally prohibition, we investigate the idea from Deep Reinforcement Learning field and experiment with Deep Q Networks that are promising to perform well in large and complicated systems.
