Version 1.1.0

Synopsis

Major Changes

• The program can now read XLSX files apart from CSV.
• Number of Clusters can now be identified with the help of a small GUI.

Minor Changes

• The segmentation objects can now be transferred and loaded to any machine.
• Waitbars are introduced and appear during specific processing stages (data parsing and feature computation) to indicate that the program is busy. During these stages the main GUI become invisible.
• Error messages are more detailed.

Details

XLSX file support

Later versions of Ethovion do not have the option of exporting the trajectory data in CSV format, but only in Excel (.*xlsx) and Text (.*txt). For this reason the support of both CSV and XLSX formats was introduced.

Number of Clusters GUI

Prior to this patch the user was required to generate a series of graphs indicating the impact of the number of clusters on the clustering performance and use these graphs to determine an ideal number of clusters for the classification process. This procedure was made more easy the the introduction of a small GUI which is activated with the pressing of the Num of Clusters button. This GUI helps the user to determine the quality of the labelling (if more and/or better labelling data are required) and also the an ideal number of clusters that will result in a 'good classification' (classification of as many trajectory segments as possible with minimum error).
