Document Type and Number:
WIPO Patent Application WO/2020/080143
Kind Code:
A1
Abstract:
Provided is a sensing system for collecting sensor data. The sensing system is provided with a sensor terminal which generates sensor data on the basis of a measurement result obtained by a sensor, and an edge node which receives the sensor data from the sensor terminal. The edge node is provided with: a dictionary learning unit which learns a dictionary composed of a matrix of base vectors, and causes the dictionary to be changed on a time-series basis; and a sparse recovery process unit which, using the dictionary that has been learned and on the basis of sparsity, performs a sparse recovery process for recovering the sensor data from the data received from the sensor terminal of which the data amount has been reduced.
