The concept of intelligent system has emerged in information technology as a type of system derived from successful applications of artificial intelligence. The goal of this paper is to give a general description of an intelligent system, which integrates previous approaches and takes into account recent advances in artificial intelligence. The paper describes an intelligent system in a generic way, identifying its main properties and functional components, and presents some common categories. The presented description follows a practical approach to be used by system engineers. Its generality and its use is illustrated with real-world system examples and related with artificial intelligence methods.

We explore the use of policy approximation for reducing the computational cost of learning Nash equilibria in multi-agent reinforcement learning scenarios. We propose a new algorithm for zero-sum stochastic games in which each agent simultaneously learns a Nash policy and an entropy-regularized policy. The two policies help each other towards convergence: the former guides the latter to the desired Nash equilibrium, while the latter serves as an efficient approximation of the former. We demonstrate the possibility of using the proposed algorithm to transfer previous training experiences to different environments, enabling the agents to adapt quickly to new tasks. We also provide a dynamic hyper-parameter scheduling scheme for further expedited convergence. Empirical results applied to a number of stochastic games show that the proposed algorithm converges to the Nash equilibrium while exhibiting a major speed-up over existing algorithms.

This article discusses recent trends and concepts in developing new kinds of artificial intelligence (AI) systems which relate to complex facets and different types of human intelligence, especially social, emotional, attentional and ethical intelligence, which to date have been under-discussed. We describe various aspects of multiple human intelligence and learning styles, which may impact on a variety of AI problem domains. Using the concept of multiple intelligence rather than a single type of intelligence, we categorize and provide working definitions of various AI depending on their cognitive skills or capacities. Future AI systems will be able not only to communicate with human actors and each other, but also to efficiently exchange knowledge with abilities of cooperation, collaboration and even co-creating something new and valuable and have meta-learning capacities. Multi-agent systems such as these can be used to solve problems that would be difficult to solve by any individual intelligent agent.

Agent-based modeling (ABM) is a powerful paradigm to gain insight into social phenomena. One area that ABM has rarely been applied is coalition formation. Traditionally, coalition formation is modeled using cooperative game theory. In this paper, a heuristic algorithm is developed that can be embedded into an ABM to allow the agents to find coalition. The resultant coalition structures are comparable to those found by cooperative game theory solution approaches, specifically, the core. A heuristic approach is required due to the computational complexity of finding a cooperative game theory solution which limits its application to about only a score of agents. The ABM paradigm provides a platform in which simple rules and interactions between agents can produce a macro-level effect without the large computational requirements. As such, it can be an effective means for approximating cooperative game solutions for large numbers of agents. Our heuristic algorithm combines agent-based modeling and cooperative game theory to help find agent partitions that are members of a games' core solution. The accuracy of our heuristic algorithm can be determined by comparing its outcomes to the actual core solutions. This comparison achieved by developing an experiment that uses a specific example of a cooperative game called the glove game. The glove game is a type of exchange economy game. Finding the traditional cooperative game theory solutions is computationally intensive for large numbers of players because each possible partition must be compared to each possible coalition to determine the core set; hence our experiment only considers games of up to nine players. The results indicate that our heuristic approach achieves a core solution over 90% of the time for the games considered in our experiment.

Has Covid-19 started to change our attitude to robots and artificial intelligence? Researchers at Heriot-Watt University think so and are working on cutting-edge techniques to ensure a safer world for us all, with the robots doing more of the dirty and dangerous jobs. Professor Helen Hastie, director of the EPSRC-funded Centre for Doctoral Training in Robotics and Autonomous Systems, says: "At Heriot-Watt, we have been working on getting robots to go into hazardous places where people can't or don't want to go, such as offshore or deep underwater. "During the current crisis, a general awareness of the utility of robots has grown, and people can see where robots might be useful in cases when human interventions are now discouraged. This can be in particular'hot-zones' that need to be avoided by people, such as homes of those shielding, and hospitals." One example of Heriot-Watt's ambition is the SPRING project, where robots are designed to reduce stress and loneliness and improve ...

With the rise of online e-commerce platforms, more and more customers prefer to shop online. To sell more products, online platforms introduce various modules to recommend items with different properties such as huge discounts. A web page often consists of different independent modules. The ranking policies of these modules are decided by different teams and optimized individually without cooperation, which might result in competition between modules. Thus, the global policy of the whole page could be sub-optimal. In this paper, we propose a novel multi-agent cooperative reinforcement learning approach with the restriction that different modules cannot communicate. Our contributions are three-fold. Firstly, inspired by a solution concept in game theory named correlated equilibrium, we design a signal network to promote cooperation of all modules by generating signals (vectors) for different modules. Secondly, an entropy-regularized version of the signal network is proposed to coordinate agents' exploration of the optimal global policy. Furthermore, experiments based on real-world e-commerce data demonstrate that our algorithm obtains superior performance over baselines.

The guidance of a large swarm is a challenging control problem. Shepherding offers one approach to guide a large swarm using a few shepherding agents (sheepdogs). Noise is an inherent characteristic in many real-world problems. However, the impact of noise on shepherding is not well-studied. This impact could take two forms. First, noise in the sensorial information received by the shepherd about the location of sheep. Second, noise in the ability of the sheepdog to influence sheep due to disturbances caused during actuation. We study both types of noise in this paper. In this paper, we investigate the performance of Str\"{o}mbom\textquoteright s approach under actuation and perception noises. Before studying the effect noise, we needed to ensure that the parameterisation of the algorithm corresponds to a stable performance for the algorithm. This pegged for running a large number of simulations, while increasing the number of random episodes until stability is achieved. We then systematically studies the impact of sensorial and actuation noise on performance. Str\"{o}mbom\textquoteright s approach is found to be more sensitive to actuation noise than perception noise. This implies that it is more important for the shepherding agent to influence the sheep more accurately by reducing actuation noise than attempting to reduce noise in its sensors. Moreover, different levels of noise required different parameterisation for the shepherding agent, where the threshold needed by an agent to decide whether or not to collect astray sheep is different for different noise levels.

In computational In this paper, we present an evolutionary path planning intelligence research, the concept is used more broadly to approach for shepherding that takes into account the collection model and analyze the behaviour of biologically inspired and movement of the swarm (sheep) in addition to the swarms, where multiple agents of different type interact with sheepdog. The problem is different from conventional path each other in a proactive and reactive manner. The reactive planning for robot navigation in the sense that the control agents are analogous to the sheep in the problem; they respond agents (sheepdog) have access to global information when to the presence of the proactive agent, the sheepdog, and are seeking an optimal path, while the movement of others (sheep) repulsed from it. The sheepdog makes a sequence of decisions is purely reactive. The two-phase algorithm starts by identifying to influence the sheep and to guide them towards a goal the path for the sheepdog to move from any initial position area. A recent comprehensive review on the subject can be to a position behind the swarm. The path is constrained to be found in [1]. The shepherding problem using robotic swarms obstacle free and so as not to impact the sheep; lest the sheep is of interest in several applications beyond the biological be repulsed and scatter, making their collection even harder inspiration of shepherding itself; applications include crowd and more time-consuming. In the second phase, the algorithm control [2], cleanup of oil spills [3], disaster relief and rescue plans the path for the sheepdog by identifying the next series operations [4], and security/military procedures [5], among of way points to guide the sheep towards their final destination.
