Real-world testing of next generation AI stock trading to commence
Japan’s first AI trading system using ensemble learning predicts trends in stock prices.

Press Release TOKYO, October 31, 2018

i’s FACTORY co., ltd. has agreed with Epic Partners Investments Co., Ltd., an independent hedge fund, to start real-world testing of the next generation AI trading system. Development of an AI trading system using ensemble learning is the first in Japan (as of September 30th, 2018).

Through the analysis of trends in stock prices, and building predictive models using machine learning, both companies have managed to build a model which in theory achieves constant return. As the next step, the model will be put to use in real-world trading in the coming months.
The traders at Epic Partners Investments will trade Japanese stocks according to the trends prediction calculated by the predictive model, to test the effectiveness in the real-world operation, and to further enhance the model’s accuracy.

Ensemble learning made possible with the unique AI platform “bodais”

Real-world test will be carried out using the AI platform “bodais”.
“bodais” is a user-friendly data analytics service with built-in machine learning feature on cloud, developed by i’s FACTORY. Its notable feature includes automatic data-cleansing function, which enables a significant reduction of time and effort needed to make raw-data ready to be analyzed.
In the latest AI trading system, the predictive model is based on ensemble learning—an analytical method whereby multiple predictive models are combined to make a single model. A vast number of virtual traders were modelled on “bodais” to enhance predictive accuracy and to reduce the chance of underfitting. For the real-world testing, the predictive model uses about 1000 variables, such as stock market indexes, exchange data, financial indicators and past trends in Japanese stock prices. Using these vast amounts of data, “bodais” automatically chooses the variables and large-scale distributed system calculates the prediction. Through these technologies (patent pending), the predictive model was deployed with a demonstrable level.
