TraX—representation space 
Application—representation of world for 
autonomous vehicle. 
“Representation space”—set of object 
representations 
An object may be represented in several 
different ways, simultaneously, depending on: 
• input data resolution 
• type of object 
Problems: 
• maintaining consistent representations across 
types 
• consistent identification of object 
Conclusions 
Optimal model type depends on: 
• object 
• task 
• system 
Other considerations than just representation. 
• Implicit assumptions about the scene and 
objects embedded in model. 
• Effect of model type on precision and 
reliability of extracted model. 
Interchange between systems is important and 
hard.
