Selective Inference for Predictive Sequence Mining and Its Applications to Trajectory Data Analysis
Kazuya Nishi,Takuto Sakuma,Yuta Umezu,Shinsuke Kajioka,Ichiro Takeuchi
Event date： 2018.06
Language：Japanese Presentation type：Oral presentation (general)
With the development of sensor devices, series data such as GPS data can be easily acquired. To extract important sequential patterns from such data, there is a data mining technique called predictive sequence mining. Evaluating the reliability of sequence patterns extracted from enormous candidates is also important to make decisions. In this paper, we propose a method combining predictive sequence mining using a linear model with L1 regularization and statistical hypothesis test considering selection bias.

Event date： 2018.03
Language：Japanese Presentation type：Oral presentation (general)
In Nagoya Institute of Technology, a position estimation service that includes Bluetooth Low Energy (BLE) beacons is used for attendance confirmation of daily lectures. This service can estimate the position of students with an error within meters. We developed a game system named SpyGame to introduce the aforementioned estimation service as a hands-on activity. Players of SpyGame walk around the campus to find the checkpoint with the help of information about the distance to the checkpoint. Throughout game-play, players use their smartphone to capture BLE beacon information continuously, so the distance to the checkpoint is shown on the screen. We utilized 1600 of already installed BLE beacons in our campus and 70 of additional BLE beacons to improve the accuracy of position estimation. In this paper, we describe the overall architecture of SpyGame and analyze data collected from the school festival.

Comparative Pattern Mining of Human Trajectory Data

In Nagoya Institute of Technology, we have developed a localization framework using BLE (Bluetooth Low Energy) beacons to estimate location of students for automated roll call.
About 1600 of BLE beacon emitters have been installed in our campus.
We are challenging to gather and analyze human trajectory using the localization framework.
In this paper, we introduce human trajectory data gathering experiment which is held on Nov. 24-25, 2017 in our campus.
169 subjects participated and 671 trajectory trips are collected during the experiment.
Each subject carries around with his/her smartphone during the experiment to receive BLE beacons and send them to a data gathering server.
The human trajectory data gathering server receives BLE beacons from smartphones and stores them to its database.
We also show results of comparative pattern mining.
By segmenting subjects by gender, we have obtained characteristic trajectory pattern from each of male and female groups. -
