As someone so flummoxed by traffic I wrote a book about it, I have a near-clinical aversion to vehicular congestion. My global default strategy is to simply drive as little as possible, but there are times when I simply must put foot to gas pedal. Like many, I have become increasingly dependent on the Waze app, which, via each drivers' smartphone, turns an inchoate, undifferentiated mass of drivers into something resembling a collective form of networked intelligence. Waze, it occurred to me the other day while stuck in a bit of unexpected congestion (which had been duly flagged by at least 13 "Wazers"), is helping us turn into ants. Every time drivers travel down a path, Waze tracks their speed--information that can then be broadcast to every following driver.

Swarm intelligence has made some impressive predictions on horse racing this season, by correctly placing the top four Kentucky Derby finishers last month. This might affect bookies but what about horses? If an "artificial" intelligence can benefit betting, can it help keep a horse healthy and performing well? A French startup called Arionea thinks so. The company is betting big that artificial intelligence (AI) and the Internet of Things (IoT) will revolutionize the racetrack -- with the help of a new device dubbed the Equimetre.

With much current discussion of AI fixating on ethical implications--whether AI may eventually "outsmart" or harm us; how we can ensure that AI acts in our best interests--it's worth considering a new approach to AI that keeps humans in the loop: swarm intelligence. UNU, a software platform run by Unanimous A.I., brings groups of people together online to arrive at all kinds of real-time decisions and predictions, ranging from who will win March Madness to the top four horses at the Kentucky Derby. The system has proven remarkably effective at coming up with accurate answers. In fact, it has outperformed experts in a variety of contests--in the 2015 Oscar predictions, for instance, the swarm had a higher than 70% accuracy--New York Times critics, it should be noted, were right 55% of the time. SEE: How'artificial swarm intelligence' uses people to make better predictions than experts But, beyond accuracy, there is another advantage to using the swarm: according to new research, it makes more ethical decisions.

Many real-world relations can be represented by signed networks with positive and negative links, as a result of which signed network analysis has attracted increasing attention from multiple disciplines. With the increasing prevalence of social media networks, signed network analysis has evolved from developing and measuring theories to mining tasks. In this article, we present a review of mining signed networks in the context of social media and discuss some promising research directions and new frontiers. We begin by giving basic concepts and unique properties and principles of signed networks. Then we classify and review tasks of signed network mining with representative algorithms. We also delineate some tasks that have not been extensively studied with formal definitions and also propose research directions to expand the field of signed network mining.

Sequence of functions above is derived from expression graph of our input function \(f\) – it decomposes our function into sequence of functions we know how to handle. Now our function is a sequence of basic operations that change variables' values. Forward mode automatic differentiation reduces to computing partial derivative with respect to chosen input dimension at given point by differentiating each of the sequence elements forward. Lets try with point \((3,5)\).

- An Autonomous Underwater Vehicle (AUV) needs to possess a certain degree of autonomy for any particular underwater mission to fulfil the mission objectives successfully and ensure its safety in all stages of the mission in a large scale operating fi e ld . In this paper, a novel combinatorial conflict - free - task ass ignment strategy consisting of an interactive engagement of a local path planner and an adaptive global route planner, is introduced. The method takes advantage of the heuristic search potency of the Particle Swarm Optimization (PSO) algorithm to address t he discrete nature of routing - task assignment approach and the complexity of NP - hard path planning problem. The proposed hybrid method, is highly efficient as a consequence of its reactive guidance framework that guarantees successful completion of mission s particularly in cluttered environments. To examine the performance of the method in a context of mission productivity, mission time management and vehicle safety, a series of simulation studies are undertaken. The results of simulations declare that the proposed method is reliable and robust, particularly in dealing with uncertainties, and it can significantly enhance the level of a vehicle's autonomy by relying on its reactive nature and capability of providing fast feasible solutions.

Loyal readers will recall that last spring we conspired with artificial intelligence expert Randal Olsen to develop the ultimate U.S. road trip. The map Olson came up with -- he did all the work, really -- optimized the best way to drive by car to 50 major U.S. landmarks, using machine learning algorithms and Google Maps. We're happy to report that Olsen is back at it, just in time for summer road tripping. By leveraging the power of genetic algorithms and other artificial intelligence technology, Olsen's optimized loop route will get you across the country and back in a little over eight days -- starting in Concord, New Hampshire, and dropping you back in Boston, Mass. How did Olsen generate his road trip map?

About a year ago, I wrote an article introducing the concept of optimizing road trips using a combination of genetic algorithms and Google Maps. During that time, I've given some thought to how I could make that algorithm more useful to folks looking to plan their summer road trips. One thought that struck me was that the road trips I created before were quite grandiose--spanning entire states or even most of Europe--such that only people who had some savings and were able to take a month off of work could even hope to go on one of the trips. In reality, most of us have budgetary constraints on our road trips: we can only spend so much money, or we only have so much time off before we have to get back to work. In this article, I'm going to expand on the idea of optimizing road trips by introducing multi-objective Pareto optimization to the algorithm.

I am excited to be here today for what is a Reddit first. This will be the first AMA in history to feature an Artificial "Hive Mind" answering your questions. You might have heard about me because I've been challenged by reporters to make lots of predictions. For example, Newsweek challenged me to predict the Oscars (link) and I was 76% accurate, which beat the vast majority of professional movie critics. I'm a Swarm Intelligence that links together lots of people into a real-time system – a brain of brains – that consistently outperforms the individuals who make me up.

That's the title of a new paper by Paul Smaldino and Richard McElreath which presents a sort of agent-based model that reproduces the growth in the publication of junk science that we've seen in recent decades. Even before looking at this paper I was positively disposed toward it for two reasons. First because I do think there are incentives that encourage scientists to follow the forking paths toward statistical significance and that encourage journalists to publish this sort of thing. And I also see incentives for scientists and journals (and even the Harvard University public relations office; see the P.P.S. here) to simply refuse to even consider the possibility that published results are spurious. The second reason I liked this paper before even reading it is that the second author recently wrote an excellent textbook on Bayesian statistics which in fact I just happened to recommend to a student a few hours ago.
