Robust regressionIn robust statistics, robust regression seeks to overcome some limitations of traditional regression analysis. A regression analysis models the relationship between one or more independent variables and a dependent variable. Standard types of regression, such as ordinary least squares, have favourable properties if their underlying assumptions are true, but can give misleading results otherwise (i.e. are not robust to assumption violations).
Emotion and memoryEmotion can have a powerful effect on humans and animals. Numerous studies have shown that the most vivid autobiographical memories tend to be of emotional events, which are likely to be recalled more often and with more clarity and detail than neutral events. The activity of emotionally enhanced memory retention can be linked to human evolution; during early development, responsive behavior to environmental events would have progressed as a process of trial and error.
Repères temporels dans la mémoire autobiographiqueLes repères temporels représentent les périodes de temps spéciaux de notre vie stockés dans la mémoire qui nous aident à organiser le stockage des autres événements. Ils jouent un rôle important dans la structuration de la mémoire autobiographique, la reconstruction et la consolidation des souvenirs stockés, l'encodage des nouveaux et la récupération des anciens souvenirs. Les repères temporels forment un système de référence personnel basé sur l'expérience et le passé personnel, différent pour chaque individu.
Memory consolidationMemory consolidation is a category of processes that stabilize a memory trace after its initial acquisition. A memory trace is a change in the nervous system caused by memorizing something. Consolidation is distinguished into two specific processes. The first, synaptic consolidation, which is thought to correspond to late-phase long-term potentiation, occurs on a small scale in the synaptic connections and neural circuits within the first few hours after learning.
Memory and agingAge-related memory loss, sometimes described as "normal aging" (also spelled "ageing" in British English), is qualitatively different from memory loss associated with types of dementia such as Alzheimer's disease, and is believed to have a different brain mechanism. Mild cognitive impairment Mild cognitive impairment (MCI) is a condition in which people face memory problems more often than that of the average person their age. These symptoms, however, do not prevent them from carrying out normal activities and are not as severe as the symptoms for Alzheimer's disease (AD).
Régression quantileLes régressions quantiles sont des outils statistiques dont l’objet est de décrire l’impact de variables explicatives sur une variable d’intérêt. Elles permettent une description plus riche que les régressions linéaires classiques, puisqu’elles s’intéressent à l’ensemble de la distribution conditionnelle de la variable d’intérêt et non seulement à la moyenne de celle-ci. En outre, elles peuvent être plus adaptées pour certains types de données (variables censurées ou tronquées, présence de valeurs extrêmes, modèles non linéaires.
ActualitéNews is information about current events. This may be provided through many different media: word of mouth, printing, postal systems, broadcasting, electronic communication, or through the testimony of observers and witnesses to events. News is sometimes called "hard news" to differentiate it from soft media. Common topics for news reports include war, government, politics, education, health, the environment, economy, business, fashion, entertainment, and sport, as well as quirky or unusual events.
Multinomial logistic regressionIn statistics, multinomial logistic regression is a classification method that generalizes logistic regression to multiclass problems, i.e. with more than two possible discrete outcomes. That is, it is a model that is used to predict the probabilities of the different possible outcomes of a categorically distributed dependent variable, given a set of independent variables (which may be real-valued, binary-valued, categorical-valued, etc.).
Intelligence collectiveL'intelligence collective ou de groupe se manifeste par le fait qu'une équipe d'agents coopérants peut résoudre des problèmes plus efficacement que lorsque ces agents travaillent isolément . Le concept d’intelligence collective a été mobilisé pour aborder des collectifs d'agents très divers : des insectes vivant en colonies, des équipes d'humains, des robots collaboratifs, bien que dans ce dernier cas il conviendrait plutôt de parler d'intelligence distribuée. Pour Pierre Lévy, il s'agit d'une .
News mediaThe news media or news industry are forms of mass media that focus on delivering news to the general public. These include news agencies, newspapers, news magazines, news channels etc. Some of the first news circulations occurred in Renaissance Europe. These handwritten newsletters contained news about wars, economic conditions, and social customs and were circulated among merchants. The first printed news appeared by the late 1400s in German pamphlets that contained content that was often highly sensationalized.
