Claim One:
1. A data processing apparatus comprising: a data obtaining section including at least one sensor configured to obtain time series data by measuring in real-time a total value of a plurality of waveforms of a plurality of physical apparatuses, and the data obtaining section is configured to convert said time series data into nonnegative data; a parameter estimating section configured to obtain a model parameter when states of said plurality of waveforms or vector time series data are modeled by a stochastic model on a basis of said converted time series data; an identical apparatus determining section configured to identify whether a first state and a second state of a physical apparatus originate in an identical physical apparatus based on results of estimation by the parameter estimating section; an apparatus identifying section configured to identify the plurality of physical apparatuses on the basis of results of determination by the identical apparatus determining section; and a display configured to display states of operation of the physical apparatuses identified by the apparatus identifying section on the basis of the results of estimation by the parameter estimating section, wherein in a parameter estimating process under constraint conditions that an observation parameter W(m) corresponding to a pattern of a waveform of a factor m of said stochastic model are nonnegative, said parameter estimating section obtains the observation parameter W(m) as said model parameter.
