4. Relevant Information Paragraph:
   People used for recording of the data were wearing four tags (ankle left, ankle right, belt and chest). 
   Each instance is a localization data for one of the tags. The tag can be identified by one of the attributes.
   
5. Number of Instances: 164860

6. Number of Attributes: 8
