Learning Combinatorial Information from Alignments of Landmarks

Proceedings 2007 IEEE International Conference on Robotics and Automation, 2007
This paper characterizes the information space of a robot moving in the plane with limited sensing. The robot has a landmark detector, which provides the cyclic order of the landmarks around the robot, and it also has a touch sensor, that indicates when the robot is in contact with the environment boundary.

Landmark learning: An illustration of associative search

Biological Cybernetics, 1981
In a previous paper we defined the associative search problem and presented a system capable of solving it under certain conditions. In this paper we interpret a spatial learning problem as an associative search task and describe the behavior of an adaptive network capable of solving it.

Landmark learning by juvenile salamanders (Ambystoma maculatum)

Behavioural Processes, 2014
Learning to use a landmark as a beacon to locate resources is one of the simplest forms of spatial learning. We tested whether landmark learning occurs in a semifossorial salamander that migrates annually to breeding ponds as adults. Juvenile spotted salamanders (Ambystoma maculatum) were tested in square containers with a plastic feeding dish in each ...

Landmark learning by honey bees

Animal Behaviour, 1987
Abstract There are two published models for landmark learning by honey bees: (1) bees remember only the presence or absence of landmarks in each of several sectors around a food source, or (2) bees store a visual image of the landmarks. Experiments reported here indicate that bees are able to remember landmarks pictorially, and store their location ...

Learning a sequential search for landmarks

2015 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2015
We propose a general method to find landmarks in images of objects using both appearance and spatial context. This method is applied without changes to two problems: parsing human body layouts, and finding landmarks in images of birds. Our method learns a sequential search for localizing landmarks, iteratively detecting new landmarks given the ...

Learning visual landmarks for pose estimation

Proceedings 1999 IEEE International Conference on Robotics and Automation (Cat. No.99CH36288C), 2003
We present an approach to vision-based mobile robot localization, even without an a-priori pose estimate. This is accomplished by learning a set of visual features called image-domain landmarks. The landmark learning mechanism is designed to be applicable to a wide range of environments.

Visual Landmark Learning

2000
Biology often offers valuable example of systems both for learning and for controlling motion. Work in robotics has often been inspired by these findings in diverse ways. Though, the fundamental aspects that involve visual landmark learning and motion control mechanisms have almost exclusively been approached heuristically rather than examining the ...

Honeybees learn the colours of landmarks

Journal of Comparative Physiology A, 1986
1. To discover whether bees learn the colours of landmarks, individually marked foragers were trained to collect sucrose from a small reservoir on the floor of a room. The reservoir was placed at one of two sites each defined by its position relative to one of two different arrays of cylindrical landmarks.

Biologically-Inspired Visual Landmark Learning for Mobile Robots

2000
This paper presents a biologically-inspired method for selecting visual landmarks which are suitable for navigating within not pre-engineered environments. A landmark is a region of the goal image which is chosen according to its reliability measured through a phase called Turn Back and Look (TBL).

Landmarks in Route Learning by Girls and Boys

Perceptual and Motor Skills, 2000
Previous research on route learning has shown that men learn routes faster and with fewer errors than women. The same patterns have also been found for girls and boys. In this study, 19 children of ages 5 to 6 years, 26 children of ages 7 to 9 years, and 22 children of ages 10 to 12 years were presented a route-learning task.
