Abstract (in Japanese) (See Japanese page) 
(in English) We can see the time-series data in this natural world,
and human economic activity has a lot of time-series data.
If accuracy of weather forecast is very high, we can avert from disaster.
Therefore, we can say the time-series prediction is very important.
Recently, many researches of prediction are carried out.
In these study, statistics methods or methods of making an equation are often used.
In our previous study, we proposed a automatic prediction system by 3x3 coupled van der Pol oscillators system.
The system was adjusted by manual and automatic.
All solutions in a limited parametric space were automatically found.
Therefore, this method automatically adjusted only 4 parameters and other parameters are adjusted by hand motion.
The accuracy of prediction was high, because optimization of human power is used.
However, calculation(prediction) time is long.

In this study, we propose a new automatic prediction method by 3x3 van der Pol oscillator's system.
This new method obtains a solution by steepest descent method, and is automatically adjust all parameter.
