How To Win At Forecasting

How To Win At Forecasting | Philosophy and Complexity | Scoop.it

The question becomes, is it possible to set up a system for learning from history that's not simply programmed to avoid the most recent mistake in a very simple, mechanistic fashion? Is it possible to set up a system for learning from history that actually learns in our sophisticated way that manages to bring down both false positive and false negatives to some degree? That's a big question mark.

Nobody has really systematically addressed that question until IARPA, the Intelligence Advanced Research Projects Agency, sponsored this particular project, which is very, very ambitious in scale. It's an attempt to address the question of whether you can push political forecasting closer to what philosophers might call an optimal forecasting frontier. That an optimal forecasting frontier is a frontier along which you just can't get any better.

PLOS ONE: Knotty-Centrality: Finding the Connective Core of a Complex Network

PLOS ONE: Knotty-Centrality: Finding the Connective Core of a Complex Network | Philosophy and Complexity | Scoop.it

A network measure called knotty-centrality is defined that quantifies the extent to which a given subset of a graph’s nodes constitutes a densely intra-connected topologically central connective core. Using this measure, the knotty centre of a network is defined as a sub-graph with maximal knotty-centrality. A heuristic algorithm for finding subsets of a network with high knotty-centrality is presented, and this is applied to previously published brain structural connectivity data for the cat and the human, as well as to a number of other networks. The cognitive implications of possessing a connective core with high knotty-centrality are briefly discussed.

Iterated Prisoner’s Dilemma contains strategies that dominate any evolutionary opponent

The two-player Iterated Prisoner’s Dilemma game is a model for both sentient and evolutionary behaviors, especially including the emergence of cooperation. It is generally assumed that there exists no simple ultimatum strategy whereby one player can enforce a unilateral claim to an unfair share of rewards. Here, we show that such strategies unexpectedly do exist. In particular, a player X who is witting of these strategies can (i) deterministically set her opponent Y’s score, independently of his strategy or response, or (ii) enforce an extortionate linear relation between her and his scores. Against such a player, an evolutionary player’s best response is to accede to the extortion. Only a player with a theory of mind about his opponent can do better, in which case Iterated Prisoner’s Dilemma is an Ultimatum Game.

What is complex systems science: Opportunities and insights. Yaneer Bar-Yam

Only 15 years ago, complex systems science had to justify its existence. Today it is taking the world by storm. Networks, big data, cascading crises, extreme events, the word "systems," and many other ideas are widely accepted and the basis for new advances and increasing the scope of science. What is this movement about, what changes are in store, and what are the opportunities for engagement? We will answer these questions, and others that you have, in this web presentation.
