Adviser: Prof. Julie A. Adams

Exploring the potential benefits of incorporating human-inspired forgetting mechanisms into robotic systems. A new model of forgetting, named ActSimple, has been developed to increase the ability of robots to wade through the waves of data generated by robotic sensors. Unlike some existing models of human forgetting and robotic systems, the proposed forgetting approach does not select items from memory, but filters the data available to existing algorithms. Through this data screening, traditional robotic algorithms may realize improved performance and increased accuracy. Results from completed experiments suggest ActSimple may not only provide the benefits of forgetting to robotics, but realize increased performance over a number of existing algorithms. ActSimple is a non-domain specific algorithm with a number of parameters and subcomponents that can be adjusted for particular domains and tasks.
