Geometric and Algebraic Methods in Multiagent Deep Reinforcement Learning with Applications to Forest Firefighting

Partners and Supporting Agencies: European Comission,  Researchers: Ahmed Farabi Tarhan, N. Kemal Ure, Dates: 2017-Present

Synopsis: Multiagent planning problems are ubiquitous in engineering, with examples ranging from multiple mobile robots used in planetary exploration to use of multiple unmanned aerial vehicles for forest firefighting. Many multiagent planning problems can be formulated as Markov Decision Processes and an approximate optimal solution can be computed with dynamic programming and reinforcement learning methods. However, these algorithms usually become computationally infeasible with the increasing number of agents. In recent years, using deep neural networks in conjunction with reinforcement learning algorithms proved to be a powerful method in solving such problems. In this project, we demonstrate applications of geometric deep learning (convolutional deep learning layers extended to non-Euclidean domains) to solution of large-scale multiagent planning problems.We also develop algebraic statistics based algrorithms for selecting exploration strategies that yield faster convergence compared to heuristic approaches.

Partners and Supporting Agencies: TUBITAK,  Researchers: Majid Moghadam, Mehmet Uğur Akçal, Batuhan Hoştaş, Anıl Yıldız, N. Kemal Ure, Dates: 2016-2018

Synopsis: The aim of this project is to develop control systems that would enable agile maneuvering for fixed and rotary wing Unmanned Aerial Vehicles (UAVs) along with the development of flight envelope protection and maneuver planning algorithms. The first and foremost objectives of the project are to expand the autonomously executable maneuver set of the military oriented UAVs and optionally piloted aircraft systems, prevent loss of control situations induced by the execution of these agile maneuvers as and hence increase the lifespan of UAVs operating in adversarial conditions. In this context, the project’s expected outcomes are algorithms that would enable the UAV to compute agile maneuvers for defending itself from threats (such as missiles and other aerial adversaries) and counter-attacking them, tracking these reference maneuvers with high accuracy and return autonomously safe flight conditions if these agile maneuvers force the aircraft the violate the flight envelope due to high angle of attack and high translational speed. The developed algorithms are verified with simulation studies on six degrees of freedom nonlinear UAV models for various different threat scenarios.

Autonomous Control of Unmanned Combat Air Vehicles: Design of a  Multimodal Control and Flight Planning Framework for Agile Maneuvering

Researchers: N. Kemal Ure, Emre Koyuncu, Gokhan Inalhan, Dates: 2006-2010

Synopsis: This project studies the problem of generation and control of maneuver profiles for Unmanned Combat Air Vehicles (UCAV) with aggressive maneuvering capability. A motion description framework is developed, where complex maneuvers are decomposed into series of sub-maneuvers (modes) and associated parameters. Main advantage of framework is allowance of the feasibility and control problems to be treated for each sub-maneuver individually instead of whole maneuver, thus reducing the complexity of the problem which can also be modeled in the language of Hybrid Dynamical Systems. For maneuver generation, agility metrics and mode compatibility relationships are used to create a feasible maneuver generation algorithm. For low level controls, each mode is assigned a Higher Order Sliding Mode Controller, where whole maneuver is controlled via switching between modes and controllers.  Overall generation and control algorithms are tested on agile combat maneuver examples.
