Abstract:

A Boolean network (BN) is well known as one of the mathematical models in gene regulatory networks. In BNs, time evolution of the state is modeled by a Boolean function. A probabilistic BN is one of the extended BNs. In PBNs, a Boolean function is randomly chosen from the candidates. In the last decade, much attention has been paid to analysis and control of BNs and PBNs. In this presentation, I will talk about two recent topics on PBNs in our research group. First, the optimal reconstruction problem is considered. In this problem, a PBN consisting of the main dynamics and the noisy dynamics can be derived from a part of Boolean functions and data. It is shown that the optimal noisy dynamics is given by a constant. Next, the pinning control problem is considered using reinforcement learning. A pinning controller can be obtained by appropriately designing a reward function.
