In many practical applications of RL, it is expensive to observe state transitions from the environment. For example, in the problem of plasma control for nuclear fusion, computing the next state for a given state-action pair requires querying an expensive transition function which can lead to many hours of computer simulation or dollars of scientific research. Such expensive data collection prohibits application of standard RL algorithms which usually require a large number of observations to learn. In this work, we address the problem of efficiently learning a policy while making a minimal number of state-action queries to the transition function. In particular, we leverage ideas from Bayesian optimal experimental design to guide the selection of state-action queries for efficient learning. We propose an acquisition function that quantifies how much information a state-action pair would provide about the optimal solution to a Markov decision process. At each iteration, our algorithm maximizes this acquisition function, to choose the most informative state-action pair to be queried, thus yielding a data-efficient RL approach. We experiment with a variety of simulated continuous control problems and show that our approach learns an optimal policy with up to 5-1, 000× less data than model-based RL baselines and 103 - 105× less data than model-free RL baselines. We also provide several ablated comparisons which point to substantial improvements arising from the principled method of obtaining data. © 2022 ICLR 2022 - 10th international conference on Learning Representationss.

Proceedings of the 10th international conference on Pattern Recognition

作者： Bernard, T. Zavidovique, B. ECTA/CREA/SP Arcueil France

the design of a compact and parallel cellular array featuring minimal-size Boolean processors associated with optoelectronic devices and nonstandard A/D (analog/digital) converters is discussed. this human-size vision machine is called Retina. It is shown that the rapprochement between acquisition and processing is particularly suited for the emergence of unique kinds of interactions between analog and digital computations. the immediate interest of analog neural computations for the nonstandard A/D conversion implied by the Retina structure is emphasized. the optimality of the corresponding process is shown. However, the authors claim that, within smart sensors, pattern recognition is better carried out by an iterative Boolean computational scheme.

Material plays an important role in product design and affects consumers’preference in purchase. To study the user’s material perception, a novel approach of the semantic differential (SD) method was adopted. Taken the cup with different material as an example, the characteristics of users’ material perception were concluded, such as transparent, reflexivity, texture, and then the weightiness of material perception was discussed. the study of the users' material perception of product will assist the designers in material design of product, and find out the material attributes and meaning for material design of product.

Multiobjective combinatorial optimization (MOCO) problems can be found in many real-world applications. However, exactly solving these problems would be very challenging, particularly when they are NP-hard. Many handcrafted heuristic methods have been proposed to tackle different MOCO problems over the past decades. In this work, we generalize the idea of neural combinatorial optimization, and develop a learning-based approach to approximate the whole Pareto set for a given MOCO problem without further search procedure. We propose a single preference-conditioned model to directly generate approximate Pareto solutions for any trade-off preference, and design an efficient multiobjective reinforcement learning algorithm to train this model. Our proposed method can be treated as a learning-based extension for the widely-used decomposition-based multiobjective evolutionary algorithm (MOEA/D). It uses a single model to accommodate all the possible preferences, whereas other methods use a finite number of solutions to approximate the Pareto set. Experimental results show that our proposed method significantly outperforms some other methods on the multiobjective traveling salesman problem, multiobjective vehicle routing problem, and multiobjective knapsack problem in terms of solution quality, speed, and model efficiency. © 2022 ICLR 2022 - 10th international conference on Learning Representationss.

In the present paper the new wind tunnel located in the Fluid-dynamic Laboratory of the Dipartimento di Ingegneria Meccanica e Gestionale (DIMeG) of the Bari Polytechnic will be shortly described and the first experimental measurements on a vertical axis wind turbine (VAWT) will be shown. the DIMeG wind tunnel has been designed by the research group on wind energy of the Department. It is a subsonic, closed loop, wind tunnel with a transparent test part where small scale models can be analyzed. A four bladed axial fan is driven by an asynchronous three phase electric motor, which is connected to an inverter in order to change the wind speed. Angular blades have been inserted at the two curves between the fan and the test section in order to increase the uniformity of the velocity profile after the two curves. An optimization fluid-dynamic study has been carried out in order to find the best blade profile. A honeycomb has been also inserted upstream the test section in order to destroy the still existing small vorticity generated by the fan and the curves. A three-axis traversing, called Cartesian robot, has been designed and built above the test section, in order to move the hot wire probe, for wind speed measurements, by means of four step by step electric motors controlled by a personal computer. A data acquisition system has been set up. All the principal commands and controls can be performed by a dedicated personal computer, which has been programmed using LabVIEW (R) G-programming language. the first experimental activity has been performed on a VAWT model, of the Giromill type with parallel blades. the turbine has been connected to an AC brushless servo, able to control the braking torque. Experimental results of the flow field in two horizontal planes have been set up using a two component hot wire probe (Dantec 55R51) calibrated with the manual system Dantec 54H10. the measurement grid adopted is formed by 20 nodes in the Y direction (main flow direction) a

Commercial airports are under increasing pressure to comply with the Eurocontrol Collaborative Decision Making (CDM) initiative, to enable overall airspace improvements. An important element of a CDM system is the provision of automated decision support to aid the controllers to schedule the take-off times and the associated times at which aircraft should push back from the stands. the CDM system then aids effective operations by communicating these scheduling decisions to other relevant parties within the airport and the airspace. One of the major CDM components is aimed at predicting the target take-off times;for medium-sized airports, a common choice for this is a "Pre-Departure Sequencer" (PDS). Here we describe the design and requirements challenges which arose during our development of a PDS system. Firstly, the scheduling problem is highly dynamic and event driven. For example aircraft can be delayed or runway capacity can change, and this requires a careful separation of data ownership responsibility between the system components and special attention to integrity constraints. Secondly, it is important to end-users that the system be predictable and, as far as possible, and transparent in its operation, with decisions that can be explained. these human factors, which influenced the choice of methods for solving the problem, are also explained in this abstract, along with the consequent decisions which were made. © PATAT 2014 - Proceedings of the 10th international conference on the Practice and theory of Automated Timetabling.

Mesh editing can provide various models for FEAsimulation in industry. this paper proposes a framework for FEA-mesh editing with feature constrained. In the framework, cage-based technique is first used to edit the basedecomposition model. Vertices of the constrained feature are transformed into a local form. Parameters are analyzed before editing operation, and our method permits the user to add constraints on the parameters of the feature. this framework can also keep consistence for the disconnected assembly mesh model. Experimental results show that constrained features are kept precisely after mesh editing. Additionally, experimental data indicate our method is efficient and achieves real-time response.

Collaboration is fundamental for cities and regions to meet the combined economic, environmental and social challenges of the 21st century. A broad array of stakeholders including citizens, non-profit organizations, private businesses, foundations, academic institutions and local governments, will need to make decisions together in order to realize a sustainable future for their communities. Our artifact was developed for the Western New York community as part of One Region Forward's planning process, developing a single portal for all stakeholders involved to continue collaborating on the plan. We developed an application that will serve as a forum to allow citizens that are passionate about sustainability to express their ideas to other citizens and plan stakeholders to build capacity and turn their ideas into action. the artifact acts as a multi-sided platform that promotes crowdsourcing for a variety of agents to come together and participate on sustainability related projects.
