Los algoritmos llegan a las mismas interpretaciones y conclusiones sobre la pintura que los expertos más reputados. Una investigación sobre arte basada en la inteligencia artificial demuestra que las métricas digitales fundamentadas en la física coinciden con los conceptos propuestos a lo largo de la historia por los expertos humanos. Así, los científicos han llegado […]
Embora a arte seja um domínio do subjetivo, um método computacional criado com base em duas medidas inspiradas pela física permitiu quantificar numericamente as mudanças de características visuais na pintura ao longo dos últimos mil anos. Os físicos Higor Sigaki e Haroldo Ribeiro, ambos da Universidade Estadual de Maringá, Paraná, e Matjaž Perc, da Universidade […]
An international research collaborative reports that a systematized AI analysis of artwork produced over the last millenium yields revealing information about historical evolutionary artistic trends. Additionally, the results map well to canonical concepts about styles and periods of art history. Art analysis is usually comparative, and has historically been conducted by individual researchers, which places […]
Moneycontrol News: Researchers may soon be able to predict corruption scandals using scientific data
The researchers constructed a dynamic network of 27 years’ worth of political corruption scandals in the country and used a time series analysis to study how the network evolves over the years. What if the 2G, CWG or the fodder scams could be predicted before they happened? Corruption, one of the biggest challenges for governance, […]
Pesquisador brasileiro transformou os escândalos de Brasília em redes – e usou algoritmos para descobrir quais serão os envolvidos num futuro próximo. Haroldo Ribeiro, professor da Universidade Estadual de Maringá (UEM), desenvolveu um método matemático capaz de prever, com 25% de precisão, quais figuras públicas serão acusadas de envolvimento em escândalos de corrupção nos próximos […]
According to the World Bank, corruption scandals siphon more than $2 trillion per year from the global economy, making corruption one of the major causes of slow economic growth and socioeconomic inequality. Now in a new study, researchers have demonstrated that it may be possible to predict who will play a role in future scandals […]
Succeeding in the male-dominated science, technology, engineering and mathematics (STEM) disciplines can be very challenging for female faculty. Now, a Northwestern University study of the collaboration patterns of STEM faculty publishing 4 November in the open-access journal PLOS Biology has found that the playing fields in some disciplines are not as level as they first […]
It is well known that when a team plays home its success rate will increase. For example, in baseball and hockey, the boost is about 8%; in international football, the increase can be 25%. In the NBA history, home teams have won about 60% of their games. This so-called “home advantage phenomenon” has motived lots […]
Análises estatísticas de campeonatos de esportes coletivos como o futebol já comprovaram que o fenômeno da “vantagem de jogar em casa” existe mesmo. Jogar em sua própria arena não é garantia de vitória, mas tende a ajudar. “Examinamos o que ocorre em uma partida para dar essa vantagem”, diz Haroldo Ribeiro, físico da Universidade Estadual […]
A wide range of indicators like wages, patents, and R&D employment increase with the population of cities. This behaviour is often referred to as urban scaling. The interesting aspect of urban scaling is that it does not follow a straight line, but rather increases exponentially. This acceleration is similar to compound interest. In some cases, […]
Desde 2003 uma equipe liderada pelo físico Geoffrey West, do Instituto Santa Fé, nos Estados Unidos, acumula evidências de que o desenvolvimento das cidades obedece a certas regularidades estatísticas. É uma espécie de física do crescimento urbano, regido por fórmulas matemáticas relativamente simples – as chamadas leis de escala ou potência – que permitem fazer […]
(Inside Science) — Similar rules may govern the squeaking of an old hardwood floor, cracking of a dried-out lump of charcoal, and shearing of our planet’s crust during an earthquake. Two recent studies in the journal Physical Review Letters have found that all of these stressful situations share the same underlying mathematical patterns. The findings […]
Two upcoming papers in Physical Review Letters shed a light on the way that scientists can use analogies to understand fundamental physical processes. Some analogies can be just plain barmy, as with Newton’s analogy between the number of notes in a musical scale and the number of colours in the rainbow (see my very first […]
A mathematical formula could predict how many murders will occur as the population in Brazil increases, say scientists. The formula can also be applied to other factors such as unemployment and literacy, they claim. Brazil is known to have extremely high murder rates, which the team argue could now be better anticipated. The scientists say […]
