Mutual-probability prediction and higher-order correlation effects among acoustic, light and electromagnetic waves in a video display terminal environment
Comptes Rendus. Mécanique, Volume 333 (2005) no. 8, pp. 642-647.

A probabilistic signal processing method, with which is possible to get some methodological suggestion to the measurement method of correlative and/or accumulative effects in the compound environment of sound, light and electromagnetic (EM) waves is discussed. In order to extract various types of latent interrelation characteristics among wave environmental factors leaked from an actually operating video display terminal (VDT), an extended regression system model, hierarchically reflecting not only linear correlation information but also nonlinear correlation information, is first introduced, especially from a viewpoint of ‘relationism-first’. Then, through estimating each regression parameter of this model, some original evaluation methods for predicting a whole probability distribution form, from one another, are proposed. Finally, the effectiveness of the methods is experimentally confirmed, by applying them to the actual observed data leaked by a VDT with some television games.

On discute une nouvelle méthode de traitement du signal susceptible d'apporter quelques suggestions d'ordre méthodologique concernant les procédés permettant de mesurer les effets corrélatifs et/ou cumulatifs dans un environnement où interagissent simultanément la lumière, les ondes électromagnétiques et acoustiques. Afin de pouvoir extraire de différents types d'interrelations caractéristiques latentes entre les facteurs provenant d'une console terminale vidéo en action, nous avons introduit un modèle étendu d'un système régressif rendant compte de manière hiérarchisée, non seulement l'information sur la corrélation linéaire, mais aussi nonlinéaire, du point de vue privilégient les « relations d'abord ». Ensuite, après avoir estimé chaque paramètre régressif de ce modèle, de nouvelles méthodes d'évaluation sont proposées permettant la prédiction de la distribution des probabilités toute entière. Finalement, l'efficacité de nos méthodes est confirmée expérimentalement grâce aux données provenant des consoles de certains jeux vidéo.
