Claim One:
1. An information processing device comprising: an acquisition unit acquiring time series data; a conversion unit generating a reduced autoregressive model based on the acquired time series data; a creation unit creating a network structure based on the reduced autoregressive model; a prediction unit predicting a future of an event, the event being currently in progress, using the reduced autoregressive model; and an output unit configured to output a prediction result from the prediction unit to a display, wherein the reduced autoregressive model satisfies an equation x(t)=a 0 +a 1 x(t−L 1 )+a 2 x(t−L 2 )+. .. a w x(t−L w )+ε(t), wherein x(t) is a term at a current time of the event, x(t−L i ) is a time delay term, L i (i=1, 2,. .. w) is an integer, a i (i=0, 1, 2,. .. w) is a parameter of the time delay term, and ε(t) is an approximation error, wherein nodes of the network are based on time delay terms of the reduced autoregressive model, and the nodes are connected to the term at the current time of the event, and wherein a direct distance between two nodes of the network is defined by a ratio, wherein the ratio is the parameter of the time delay term divided by a square root of a sum of squares of all parameters of respective terms in the reduced autoregressive model.
