This package contains the datasets and supplementary materials used in the IPIN 2017 Competition (Sapporo, Japan). Contents: Track3_LogfileDescription_and_SupplementaryMaterial.pdf: Description of the logfiles and supplemental materials. Track3_TechnicalAnnex.pdf: Technical annex describing the competition 01-Logfiles: This folder contains a subfolder with the 25 training logfiles, a subfolder with the 9 validation logfiles, and a subfolder with the 7 blind evaluation logfiles as provided to competitors. 02-Supplementary_Materials: This folder contains the Matlab/Octave parser, the raster maps, the visualization of the training routes and the location of the BLE beacon (CAR) and some Wi-Fi APs (UJIUB). 03-Evaluation: This folder contains the scripts used to calculate the competition metric, the 75th percentile on the 505 evaluation points. The ground truth is also provided in MatLab format and as a CSV file. Since the results must be provided with a 2Hz freq. starting from apptimestamp 0, the GT includes the closest timestamp matching the timing provided by competitors.
