Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes rank minimization and matrix factorization (MF) based interpolations of received signal strength (RSS) from a transmitter mounted on moving robot in factory environment.
For realizing the reliable wireless communication, machine learning based channel prediction methods have been intensively studied in the past decade.
However, some traffic models will make the observation of RSS sequence be intermittent, and the missing values must be interpolated before input to the predictor.
Classical interpolation such as linear interpolation cannot appropriately estimate the missing values because the result of the interpolation depends on the observation time.
In this paper, we propose to apply an rank minimization and MF-based interpolation techniques to RSS interpolation in order to restore the true RSS variation pattern.
The simulation results show that the proposed interpolations can improve the prediction accuracy of the machine learning based channel prediction method.
