Abstract

Developing the ability to recognize a landmark from a visual image of a robot‘s current location is a fundamental problem in robotics. We describe a way in which the landmark matching problem can be mapped to that of learning a one-dimensional geometric pattern. The first contribution of our work is an efficient noise-tolerant algorithm(designed using the statistical query model) to PAC learn the class ofone-dimensional geometric patterns. The second contribution of ourwork is an empirical study of our algorithm that provides someevidence that statistical query algorithms may be valuable for use inpractice for handling noisy data.
