Coordinated Exploration in Concurrent Reinforcement Learning

arXiv.org Artificial Intelligence

We consider a team of reinforcement learning agents that concurrently learn to operate in a common environment. We identify three properties - adaptivity, commitment, and diversity - which are necessary for efficient coordinated exploration and demonstrate that straightforward extensions to single-agent optimistic and posterior sampling approaches fail to satisfy them. As an alternative, we propose seed sampling, which extends posterior sampling in a manner that meets these requirements. Simulation results investigate how per-agent regret decreases as the number of agents grows, establishing substantial advantages of seed sampling over alternative exploration schemes.


A.I. perfectly predicted last year's Super Bowl score. What happens to betting?

#artificialintelligence

Competitive sports are ultimately numbers games. Whether it's a gymnast racking up points on a balance beam, a tennis player acing her opponent, or a football team scoring on a last second Hail Mary, all matches are won and lost by numbers. There are upsets, comebacks, and situations when the losing team still seems to outperform the other -- but, even then, victory distills into digits. As such, it's obvious that many sports lend themselves nicely to the type of mathematical analyses that let keen-eyed statisticians predict outcomes -- maybe even exact scores -- just by crunching a bunch of numbers. After all, that's the basis of sports betting, and it's helped baseball managers craft winning teams on a tight budget just by considering little more than batting average, runs batted in, and stolen bases.

10 principles of intelligent agent design

@machinelearnbot

Intelligent agents are fast becoming ubiquitous in personal life and business, which means they are an important area of opportunity and interest for innovators. As entrepreneurs, designers, product managers, developers, and investors, we should step back and think about the principles behind what we're building. It's a great time to start laying out practices and principles for how we want to design and build intelligent agents. As part of that thought process, below are 10 principles that can help govern the future design of intelligent agents. An intelligent agent should be of service to others.



How linguistic descriptions of data can help to the teaching-learning process in higher education, case of study: artificial intelligence

arXiv.org Artificial Intelligence

Artificial Intelligence is a central topic in the computer science curriculum. From the year 2011 a project-based learning methodology based on computer games has been designed and implemented into the intelligence artificial course at the University of the Bio-Bio. The project aims to develop software-controlled agents (bots) which are programmed by using heuristic algorithms seen during the course. This methodology allows us to obtain good learning results, however several challenges have been founded during its implementation. In this paper we show how linguistic descriptions of data can help to provide students and teachers with technical and personalized feedback about the learned algorithms. Algorithm behavior profile and a new Turing test for computer games bots based on linguistic modelling of complex phenomena are also proposed in order to deal with such challenges. In order to show and explore the possibilities of this new technology, a web platform has been designed and implemented by one of authors and its incorporation in the process of assessment allows us to improve the teaching learning process.


Game-theory insights into asymmetric multi-agent games DeepMind

@machinelearnbot

Game theory is a field of mathematics that is used to analyse the strategies used by decision makers in competitive situations. It can apply to humans, animals, and computers in various situations but is commonly used in AI research to study "multi-agent" environments where there is more than one system, for example several household robots cooperating to clean the house. Traditionally, the evolutionary dynamics of multi-agent systems have been analysed using simple, symmetric games, such as the classic Prisoner's Dilemma, where each player has access to the same set of actions. Although these games can provide useful insights into how multi-agent systems work and tell us how to achieve a desirable outcome for all players - known as the Nash equilibrium - they cannot model all situations. Our new technique allows us to quickly and easily identify the strategies used to find the Nash equilibrium in more complex asymmetric games - characterised as games where each player has different strategies, goals and rewards.


Trump Says Global Cooperation Can Be Part of 'America First'

U.S. News

The meeting with Kagame comes not long after participants in a White House meeting said Trump had referred to African nations as "shitholes." And Trump has come under fire in Britain after he retweeted videos from a far-right British group and criticized London Mayor Sadiq Khan following a terror attack last year. Trump canceled plans for a recent trip to London to open the new $1 billion U.S. embassy there, a move that avoided protests promised by political opponents. The president said he skipped the trip because he was unhappy with the new embassy's cost and location.


Ontology-based Fuzzy Markup Language Agent for Student and Robot Co-Learning

arXiv.org Artificial Intelligence

An intelligent robot agent based on domain ontology, machine learning mechanism, and Fuzzy Markup Language (FML) for students and robot co-learning is presented in this paper. The machine-human co-learning model is established to help various students learn the mathematical concepts based on their learning ability and performance. Meanwhile, the robot acts as a teacher's assistant to co-learn with children in the class. The FML-based knowledge base and rule base are embedded in the robot so that the teachers can get feedback from the robot on whether students make progress or not. Next, we inferred students' learning performance based on learning content's difficulty and students' ability, concentration level, as well as teamwork sprit in the class. Experimental results show that learning with the robot is helpful for disadvantaged and below-basic children. Moreover, the accuracy of the intelligent FML-based agent for student learning is increased after machine learning mechanism.
