英文摘要:
In order to use the advanced inference techniques available for Ising models, we transform complex data (real vectors) into binary strings, by local averaging and thresholding. This transformation introduces parameters, which must be varied to characterize the behaviour of the system. The approach is illustrated on financial data, using three inference methods -- equilibrium, synchronous and asynchronous inference -- to construct functional connections between stocks. We show that the traded volume information is enough to obtain well known results about financial markets, which use however the presumably richer price information: collective behaviour (\"market mode\") and strong interactions within industry sectors. Synchronous and asynchronous Ising inference methods give results which are coherent with equilibrium ones, and more detailed since the obtained interaction networks are directed.

中文摘要:
为了使用伊辛模型可用的高级推理技术,我们通过局部平均和阈值化将复杂数据(实向量)转换为二进制字符串。这种转换引入了参数,这些参数必须改变以表征系统的行为。该方法以金融数据为例,使用三种推理方法——均衡推理、同步推理和异步推理——来构建股票之间的函数关系。我们表明,交易量信息足以获得有关金融市场的众所周知的结果,而金融市场使用了可能更丰富的价格信息:集体行为(“市场模式”)和行业部门内的强大互动。同步和异步伊辛推理方法给出的结果与平衡结果一致,并且由于得到的相互作用网络是定向的,因此更加详细。
