In this paper, a new approach is developed handling the correspondence problem due to the difference in embodiment between imitator and demonstrator in imitation learning. In our work the imitator is a fluidic system of dynamics totally different than the demonstrator which is human hand gestures. In this work we demonstrate the fluidic formation control so as to generate basic hand preshaping features. Our fluidic formation control is based on Smoothed Particle Hydrodynamics (SPH), which is a particle based lagrangian method. The controller adjusts fluid parameters such as body force (f), density and velocity of particles (V) to generate particle formation mimicking hand preshapes.

Imitation of basic hand preshapes by fluid based method: fluidics formation control
Tilki, Umut; Erkmen, İsmet; Erkmen, Aydan Müşerref (2011-01-01)
In this paper, a new approach is developed, avoiding the correspondence problem caused by the difference in embodiment between imitator and demonstrator in imitation learning. In our work, the imitator is a fluidic system of dynamics totally different than the imitatee, which is a human performing hand gestures. The fluidic system is composed of fluid particles, which are used for the discretization of the problem domain. In this work, we demonstrate the fluidics formation control so as to imitate by observ...
Imitation of human body poses and hand gestures using a particle based fluidics method
Tilki, Umut; Erkmen, İsmet; Erkmen, Aydan Müşerref; Department of Electrical and Electronics Engineering (2012)
In this thesis, a new approach is developed, avoiding the correspondence problem caused by the difference in embodiment between imitator and demonstrator in imitation learning. In our work, the imitator is a fluidic system of dynamics totally different than the imitatee, which is a human performing hand gestures and human body postures. The fluidic system is composed of fluid particles, which are used for the discretization of the problem domain. In this work, we demonstrate the fluidics formation control s...
Imitation of Hand Postures with Particle Based Fluidics Method
Tilki, Umut; Erkmen, İsmet; Erkmen, Aydan Müşerref (2010-10-22)
The correspondence problem is an important problem when the subjects have two different kinematical structures imitating each other. In this new approach, the imitator and the imitate have totally different dynamics systems, the first one is the fluidic system, the second one is the human hand gestures. The motion of the fluidic system is composed of the combination of fluid particles which are used for the discretization of the problem domain. Observed human hand gestures are imitated by these fluid partic...
GENERATING EFFECTIVE INITIATION SETS FOR SUBGOAL-DRIVEN OPTIONS
DEMİR, ALPER; Cilden, Erkin; Polat, Faruk (World Scientific Pub Co Pte Lt, 2019-03-01)
Options framework is one of the prominent models serving as a basis to improve learning speed by means of temporal abstractions. An option is mainly composed of three elements: initiation set, option's local policy and termination condition. Although various attempts exist that focus on how to derive high-quality termination conditions for a given problem, the impact of initiation set generation is relatively unexplored. In this work, we propose an effective goal-oriented heuristic method to derive useful i...
Fast Elimination Method for Pruning in POMDPs
Ozgen, Selim; Demirekler, Mübeccel (2016-09-30)
This paper aims to speed up the pruning procedure that is encountered in the exact value iteration in POMDPs. The value function in POMDPs can be represented by a finite set of vectors over the state space. In each step of the exact value iteration algorithm, the number of possible vectors increases linearly with the cardinality of the action set and exponentially with the cardinality of the observation set. This set of vectors should be pruned to a minimal subset retaining the same value function over the ...
