Abstract: Reinforcement learning with multiple, potentially conflicting objectives is pervasive in real-world applications, while this problem remains theoretically under-explored. This paper tackles the multi-objective reinforcement learning (MORL) problem and introduces an innovative actor-critic algorithm named MOAC which finds a policy by iteratively making trade-offs among conflicting reward signals. Notably, we provide the first analysis of finite-time Pareto-stationary convergence and corresponding sample complexity in both discounted and average reward settings. Our approach has two salient features: (a) MOAC mitigates the cumulative estimation bias resulting from finding an optimal common gradient descent direction out of stochastic samples. This enables provable convergence rate and sample complexity guarantees independent of the number of objectives; (b) With proper momentum coefficient, MOAC initializes the weights of individual policy gradients using samples from the environment, instead of manual initialization. This enhances the practicality and robustness of our algorithm. Finally, experiments conducted on a real-world dataset validate the effectiveness of our proposed <a href="http://method.Room:" target="_blank" title="method.Room:">method.Room: 430, Bldg: EOW, University of Victoria, Victoria, British Columbia, Canada

There is a concern about the adverse health effects of exposure to electromagnetic fields (EMF) radiated from the numerous wireless devices and base stations. This becomes more critical as wireless technologies have rapidly evolved, implementing the mm-wave frequency range to fulfill massive communication demands. EMF exposure can be categorized into two parts: at lower frequencies (below 6 GHz) and high frequencies (above 6 GHz). For lower frequencies, the EMF exposure is quantified by a specific absorption rate (SAR), while for high frequencies, the EMF exposure is quantified by power density (PD). Compliance with EMF exposure limits is necessary for designing wireless devices and <a href="http://networks.Furthermore" target="_blank" title="networks.Furthermore">networks.Furthermore, the introduction of millimeter-wave (mm-wave) frequencies in cellular networks addresses the need for high-speed wireless communication. However, mm-wave signals experience high attenuation predominantly due to their susceptibility to blockage and high directivity. This consequently causes non-line-of-sight (NLOS) conditions and signal attenuations. A reconfigurable intelligent surface (RIS) is one of the possible methods that can solve blockage issues by passively reflecting and rerouting mm-wave signals in desired directions. RIS can enhance network coverage and decrease the effects of blockages compared to networks without <a href="http://RISs.Speaker(s):" target="_blank" title="RISs.Speaker(s):">RISs.Speaker(s): Norhuda, Dr. NorRoom: 212, Bldg: E, 1 Georgian Drive, Barrie, Ontario, Canada, L4M 3X9

Abstract:It is well known that a beamformer aims to receive the signal-of-interest at a possibly known direction-of-arrival while suppressing the surrounding interferences and noise. In this talk, the beamforming concept is exploited to the application of video background and object extraction. The formulated problems are solved by alternating direction method of multipliers, fixed point iterations, and Lagrange programming neural network. Experimental results on real video sequences with different complex backgrounds demonstrate the excellent performance of the proposed approach.

In this talk, I will review recent progress in my research group into main electromagnetic meta-devices: the discrete metasurface and the directional <a href="http://source.The" target="_blank" title="source.The">source.The discrete metasurface is an approach to treat the metasurface as an inherently pixelated surface with spatially discrete electromagnetic properties. Through taking this approach, we understand how discretization changes the metasurface performance and to what degree the metasurface can tolerate discretization. In some cases, we can also achieve functionalities which are impossible or unobvious to the continuous metasurface. Aggressive discretization can help to enlarge the size of the meta-atom, enabling enhanced bandwidth, reduction of fabrication tolerance, and the design of multifunction and intelligent metasurfaces for sensing, communication and <a href="http://imaging.Directional" target="_blank" title="imaging.Directional">imaging.Directional electromagnetic sources have attracted much recent attention as they form building blocks to meta-devices that manipulate the travel direction of electromagnetic waves. We juxtapose the near- and far-field properties of the circular, Huygens, and Janus dipoles, and show that the Huygens and Janus dipoles both exhibit directional near-field coupling behavior, but possess very different far-field radiation behaviors. This gives them complementary application potentials. While existing Janus dipoles are essentially sub-wavelength structures that scatter a small part of an incident wave, we introduce the Janus antenna – an active Janus dipole fed by a transmission line, which dramatically increases the power throughput and the bandwidth over which the near-field directional behavior can be achieved. The Janus dipole can be used as either an antenna a meta-device or a meta-atom, with promising potentials in directional switching, MIMO antenna and compact WPT <a href="http://systems.Biography:Alex" target="_blank" title="systems.Biography:Alex">systems.Biography:Alex M.

A brief introduction is first given to the popular explicit finite-difference time-domain (FDTD) scheme, which is subjected to Courant-Friedrichs-Lewy (CFL) stability condition. This is followed by the development of various implicit FDTD schemes, which are unconditionally stable FDTD methods without the constraint of CFL time-step size. These methods include alternating direction implicit (ADI) FDTD, locally one-dimensional (LOD) FDTD, split-step (SS) FDTD, Crank-Nicolson direct splitting (CNDS), leapfrog ADI/LOD, complying-divergence implicit (CDI) FDTD, etc. They are discussed in the context of matrix exponential and classical implicit schemes named after Peaceman-Rachford, Douglas-Gunn, D’Yakonov, Strang, Crank-Nicolson, etc. It is noted that many classical and recent implicit methods can be transformed and unified under the same family of fundamental schemes. Such family of schemes feature similar update procedures with concise matrix-operator-free right-hand sides involving only vector operations. Since vector operations are much less expensive than matrix ones, the fundamental schemes are simpler and more efficient than many previous implicit FDTD methods of similar accuracy. A comparative study of various unconditionally stable FDTD methods is carried out, which includes comparisons of their update equations and efficiency gains (flops reduction) along with insights into their inter-relations. Extension of FDTD method is also presented based on new fundamental EM quantities of field-impulses that replace fields and potentials/gauge. Such method is applicable to solve all static and dynamic problems due to all charges and/or currents. Efficient implementations of fundamental schemes of FDTD methods on mobile devices are discussed for enhanced EM teaching and learning with real-time simulations anytime, <a href="http://anywhere.Abstract" target="_blank" title="anywhere.Abstract">anywhere.Abstract (DL talk 2: Fundamental Quantity and Equations for Electromagnetics from Classical to Quantum – Replacing 160-Year-Old Maxwell Equations for Classical and Quantum)It has been 160 years now since Maxwell completed his equations of electromagnetics (EM) in 1865. Today, these equations have been written in our familiar beautiful form, in terms of fields (E and B) typically and potentials (A and phi) occasionally. However, since Maxwell-Hertz-Heaviside era, there have been longstanding dilemma to use either fields or potentials (or both) for EM, and for the potentials, which gauge condition should be imposed, e.g. Lorenz gauge, Coulomb gauge, etc. The present talk will introduce new gauge-invariant physical quantity of field-impulses for new fundamental equations of electromagnetics. Unlike the potentials that are gauge-dependent and may not be physical nor causal, the field-impulses are like fields being gauge-independent, physically real, causal and measurable. Using single wave equation in terms of electric field-impulse can provide the complete description of all electromagnetics. The electric field-impulse is the single physical quantity that can unify not only electrodynamics but also electrostatics and magnetostatics, which otherwise remain independent and left separated all this while. It can completely embed all fields and potentials attributed to static/dynamic and steady/nonsteady charge and/or current distributions. The field-impulses facilitate the development of finite-difference time-domain (FDTD) method for simulating all electromagnetic phenomena, even including electrostatics (recall that traditional FDTD has no static charge which calls for Poisson/Laplace equation!). Moreover, unlike the fields that under-describe quantum-EM, the field-impulse can explain fully the Aharonov-Bohm (AB) effect and appear naturally in Schrodinger equation. The field-impulses not only resolve the century-old field-potential/gauge dilemma, but also aptly describe quantum-EM interactions. They constitute the fundamental physical quantities that are promising for replacing fields, potentials, and ultimately Maxwell equations from classical to <a href="http://quantum.Biography:Eng" target="_blank" title="quantum.Biography:Eng">quantum.Biography:Eng Leong Tan (SM’06) received the B.Eng.
