High Level Imitation Learning in a Treasure Hunting Task

by Mary Felkin, Yves Kodratoff
"... High level learning by imitation consists of learning to emulate high level human cognitive processes. We have been able to solve this problem within a specific setting, searching for a treasure in a maze. The human behaviour can be recorded as time series of observable variables, representing the p ..."

Let’s Go for a Treasure Hunt

by Mei Yii Lim, Mary Ellen Foster, Srini Jarnathanam, Amol Deshmukh, Ruth Aylett
"... Abstract. This paper presents a study designed to explore the effect of feedback on perception of an embodied agent as well as the overall performance and experience of primary school children aged 12-13 car-rying out a treasure hunt activity. We use an embodied agent to compare three experimental c ..."

conditions: no feedback, neutral feedback, and affec-tive feedback. What the students think about the embodied agent and how they feel about the task under the different conditions will be elicited through a questionnaire upon completion of the treasure hunt activity. Moreover, how each condition affects

Dynamically Formed Heterogeneous Robot Teams Performing Tightly-Coordinated Tasks

by E. G. Jones, T. K. Harris, B. Browning, M. B. Dias, B. Argall, A. Rudnicky, M. Veloso, A. Stentz - Proceedings of the International Conference on Robotics and Automation , 2006
"... As we progress towards a world where robots play an integral role in society, a critical problem that remains to be solved is the Pickup Team challenge; that is, dynamically formed heterogeneous robot teams executing coordinated tasks where little information is known a-priori about the tasks, the r ..."

"... In this paper we aim to investigate the key drivers of international alliance formation from the perspective of Chinese companies. Our results indicate that Chinese companies enter into alliances with Western companies mainly to get accesses to international markets and to develop their technologica ..."

their technological and managerial competences further. Therefore we can say that Chinese companies particularly value task-related criteria when selecting Western partners. Nevertheless we also find that Chinese companies also include ‘soft ’ factors such trust, compatibility or reputation in their partner selection

Treasure hunting for humanoids robot

by O. Stasse, T. Foissotte, D. Larlus, A. Kheddar, K. Yokoi - In IEEE RAS/RSJ international , 2008
"... Abstract—This paper intends to describe the current status of our group in trying to make a humanoid robot autonomously build an internal representation of an object, and later on to find it in an unknown environment. This problem is named “treasure hunting”. In both cases, the main difficulty is to ..."

Affective Feedback for a Virtual Robot in a Real-World Treasure Hunt

by Mary Ellen, Foster Mei, Yii Lim, Amol Deshmukh, Srinivasan Janarthanam, Helen Hastie, Ruth Aylett
"... We explore the effect of the behaviour of a virtual robot agent in the context of a real-world treasure-hunt activity carried out by children aged 11–12. We compare three conditions: a traditional paper-based treasure hunt, along with a virtual robot on a tablet which provides either neutral or affe ..."

or affective feedback during the treasure hunt. The initial results of the study suggest that the use of the virtual robot increased the perceived difficulty of the instruction-following task, while the affective robot feedback in particular made the questions seem more difficult to answer.

Heuristic-Driven "Treasure Hunt" with Linear Performance Guarantees

by Yury V. Smirnov, Sven Koenig, Manuela M. Veloso
"... Consider the task of reaching a goal state in a partially or completely unknown domain. To accomplish such a task search algorithms have to explore the domain sufficiently to locate a goal state and a path leading to it, performing therefore what we call uninformed "treasure hunt." Very of ..."

Treasure Hunting Perfect Euler bricks

by unknown authors
"... An Euler brick is a cuboid with integer side dimensions such that the face diagonals are integers. Already in 1740, families of Euler bricks have been found. Euler himself constructed more families. If the space diagonal of an Euler brick is an integer too, an Euler brick is called a perfect Euler b ..."

brick. Nobody has found one. There might be none. Nevertheless, it is an entertaining sport to go for this treasure hunt for rational cuboids and search- of course with the help of computers. We especially look in this lecture at Soundersons parametrizations and give a short proof of a theorem of Spohn

Particle Filters for Positioning, Navigation and Tracking

by Fredrik Gustafsson, Fredrik Gunnarsson, Niclas Bergman, Urban Forssell, Jonas Jansson, Rickard Karlsson, Per-Johan Nordlund , 2002
"... A framework for positioning, navigation and tracking problems using particle filters (sequential Monte Carlo methods) is developed. It consists of a class of motion models and a general non-linear measurement equation in position. A general algorithm is presented, which is parsimonious with the part ..."
Abstract - Cited by 219 (23 self) - Add to MetaCart
filter can be used for positioning based on cellular phone measurements, for integrated navigation in aircraft, and for target tracking in aircraft and cars. Finally, the particle filter enables a promising solution to the combined task of navigation and tracking, with possible application to airborne
