I’m thinking that the RPG belief place/space will appear more trustworthy if they associate the spaces with the places (rooms, then discussion) as opposed to building the maps emphasising the problem solving discussion. I think that this will make sense, as everyone will share the room part of the story, while it’s far less likely that everyone will have the same experience in the room. The starting point, shared by all, is the “you are in a room with a troll sleeping next to a chest”. Everything else is a path leading from that starting point.

The Einstein summation convention is the ultimate generalization of products such as matrix multiplication to multiple dimensions. It offers a compact and elegant way of specifying almost any product of scalars/vectors/matrices/tensors. Despite its generality, it can reduce the number of errors made by computer scientists and reduce the time they spend reasoning about linear algebra. It does so by being simultaneously clearer, more explicit, more self-documenting, more declarative in style and less cognitively burdensome to use
- Echo chambers in online social networks, in which users prefer to interact only with ideologically-aligned peers, are believed to facilitate misinformation spreading and contribute to radicalize political discourse. In this paper, we gauge the effects of echo chambers in information spreading phenomena over political communication networks. Mining 12 millions of Twitter messages, we reconstruct a network in which users interchange opinions related to the impeachment of former Brazilian President Dilma Rousseff. We define a continuous polarization parameter that allows to quantify the presence of echo chambers, reflected in two communities of similar size with opposite views of the impeachment process. By means of simple spreading models, we show that the capability of users in propagating the content they produce, measured by the associated spreadability, strongly depends on the their polarization. Users expressing pro-impeachment sentiments are capable to transmit information, on average, to a larger audience than users expressing anti-impeachment sentiments. Furthermore, the users’ spreadability is strictly correlated to the diversity, in terms of political polarization, of the audience reached. Our findings demonstrate that political polarization can hinder the diffusion of information over online social media, and shed light upon the mechanisms allowing to break echo chambers.
- Through a systematic literature review method, in this work we searched classical electronic libraries in order to find the most recent papers related to fake news detection on social medias. Our target is mapping the state of art of fake news detection, defining fake news and finding the most useful machine learning technique for doing so. We concluded that the most used method for automatic fake news detection is not just one classical machine learning technique, but instead a amalgamation of classic techniques coordinated by a neural network. We also identified a need for a domain ontology that would unify the different terminology and definitions of the fake news domain. This lack of consensual information may mislead opinions and conclusions.
- In this paper, a model for a spatial network evolution based on a Metropolis simulation is presented. The model uses an energy function that depends both on the distance between the nodes and the stated preferences. The agents influence their network neighbors opinions using the CODA model. That means each agent has a preference between two options based on its probabilistic assessment of which option is the best one. The algorithm generates realistic networks for opinion problems as well as temporal dynamics for those networks. The transition from a random state to an ordered situation, as temperature decreases, is described. Different types of networks appear based on the relative strength of the spatial and opinion components of the energy.
