IoT Acceleration Lab to Hold the Third Big Data Analysis Contest

The IoT Acceleration Lab  has been tasked with the creation and public implementation of advanced projects using IoT. As one of the efforts, it decided to hold an event titled the “Third Big Data Analysis Contest” and will launch a call for applicants on October 2, 2017. We are looking forward to receiving your application.

1. Purpose

With the technological advent of IoT, AI and big data, the structures of industries and society itself are seeing significant changes. In response to this situation, the IoT Acceleration Lab aims to create advanced projects utilizing IoT in Japan and to publicly implement the results. To this end, it has been undertaking various efforts, including the review of necessary regulations and relevant systems, demonstration projects for the development of necessary environments (e.g., stipulating new rules across industries), and the feasibility study on which these efforts are premised.

As one of its efforts, the IoT Acceleration Lab has been holding the Big Data Analysis Contest, aiming to create case examples of entities that utilize big data as well as to cultivate and foster relevant human resources. It held the first contest focusing on the field of tourism from December 2015 to January 2016, and the second contest focusing on the field of distribution and retailing from July to August 2016.

The IoT Acceleration Lab hereby announces that it will hold the Third Big Data Analysis Contest focusing on the fields of electricity and meteorology. In the contest, participants will compete online against each other in the development of algorithms, tackling big data provided by Tokyo Electric Power Company Holdings, Inc. and the Japan Meteorological Agency, and also data-analysis assignments utilizing big data. In the contest, winners will be selected and recognized for their development of outstanding algorithms with excellent predictive accuracy and modeling ideas, and also for their ability to produce visual representations of data through the utilization of big data analysis. We are looking forward to receiving your applications
