In this paper, a set of data is assumed to be obtained from an experiment that satisfies a Boolean dynamic process. For instance, the dataset can be obtained from the diagnosis of describing the diffusion process of cancer cells. With the observed datasets, several methods to construct the dynamic models for such Boolean networks are proposed. Instead of building the logical dynamics of a Boolean network directly, its algebraic form is constructed first and then is converted back to the logical form. Firstly, a general construction technique is proposed. To reduce the size of required data, the model with the known network graph is considered. Motivated by this, the least in-degree model is constructed that can reduce the size of required data set tremendously. Next, the uniform network is investigated. The number of required data points for identification of such networks is independent of the size of the network. Finally, some principles are proposed for dealing with data with errors.
在本文中,假设一组数据是从满足布尔动态过程的实验中获得的。例如,数据集可以从描述癌细胞扩散过程的诊断中获得。利用观察到的数据集,提出了几种构建此类布尔网络动态模型的方法。不是直接构建布尔网络的逻辑动态,而是首先构建其代数形式,然后再转换回逻辑形式。首先,提出了一种通用的构建技术。为了减少所需数据的大小,考虑具有已知网络图的模型。受此启发,构建了入度最小模型,该模型可以极大地减少所需数据集的大小。接下来,研究了均匀网络。识别此类网络所需的数据点数与网络大小无关。最后,提出了一些处理有误差数据的原则。
