More than 45 years of IEP/TP research and a few focused on IEP/TP functions or roles. Yet, the quality of an IEP/TP relies on the functions that it fulfills to satisfy the needs of its different users (Petitdemange,1985). The Quebec Ministry of Education (MEQ, 2004) and the Office of Special Education and Rehabilitative Services within the U.S. Department of Education (in Eichler, 1999) explicitly identified and described six to seven IEP/TP functions. However, a literature review and practising environments highlighted a greater number of functions. The goal of this research is to identify the different functions that an IEP/TP should fulfill in regard to the different needs of its diverse users. With the use of pedagogical value analysis method (PVA), results show a synthesis of more than 700 functions organized in an IEP/TP Functional Specification Matrix (FSM). The IEP /TP FSM is useful to create, monitor and evaluate IEP/TPs, Plus de 45 ans de recherche sur les PI/PT et peu d’études portent sur les rôles ou les fonctions d’un PI/PT. Or, l’efficacité d’un PI/PT repose sur les fonctions qu’il remplit pour satisfaire les besoins de ses différents utilisateurs (Petitdemange,1985). Le Ministère de l’éducation du Québec (MEQ, 2004) ainsi que l’Office of Special Education and Rehabilitative Services des États-Unis (US department of Education) (dans Eichler, 1999) identifient et décrivent explicitement cinq à six fonctions du PI/PT. Cependant, la recension des écrits et les milieux de pratique au niveau international mettent en évidence un plus grand nombre de fonctions. Le but de la présente recherche est de cibler les différentes fonctions d’un PI/ PT au regard des besoins de ses divers utilisateurs. Ayant utilisé la méthode de l’analyse de la valeur pédagogique (AVP), les résultats présentent une synthèse de plus de 700 fonctions qui ont catégorisées, caractérisées, hiérarchisées et valorisées dans un Cahier des Charges Fonctionnel (CdCF). Enfin, le CdCF est utilisé pour la conception et l’évaluation des PI/PT, Mais de 45 anos de pesquisa IEP / TP e alguns focados em funções ou papéis IEP / TP. Já a qualidade de um IEP / TP depende das funções que ele cumpre para satisfazer as necessidades de seus diferentes usuários (Petitdemange, 1985). O Ministério da Educação de Quebec (MEQ, 2004) e o Escritório de Educação Especial e Serviços de Reabilitação do Departamento de Educação dos Estados Unidos (em Eichler, 1999) identificaram e descreveram explicitamente de seis a sete funções IEP / TP. No entanto, uma revisão da literatura e ambientes de prática destacaram um maior número de funções. O objetivo desta pesquisa é identificar as diferentes funções que um IEP / TP deve cumprir em relação às diferentes necessidades de seus diversos usuários. Com o uso do método de análise de valor pedagógico (PVA), os resultados mostram uma síntese de mais de 700 funções organizadas em uma Matriz de Especificação Funcional (FSM) IEP / TP. O IEP / TP FSM é útil para criar, monitorar e avaliar IEP / TPs, Más de 45 años de investigación de IEP / TP y algunos enfocados en funciones o roles de IEP / TP. Sin embargo, la calidad de un IEP / TP depende de las funciones que cumple para satisfacer las necesidades de sus diferentes usuarios (Petitdemange, 1985). El Ministerio de Educación de Quebec (MEQ, 2004) y la Oficina de Educación Especial y Servicios de Rehabilitación dentro del Departamento de Educación de los Estados Unidos (en Eichler, 1999) identificaron y describieron explícitamente de seis a siete funciones del IEP / TP.

Modern neural network performance typically improves as model size increases. A recent line of research on the Neural Tangent Kernel (NTK) of over-parameterized networks indicates that the improvement with size increase is a product of a better conditioned loss landscape. In this work, we investigate a form of over-parameterization achieved through ensembling, where we define collegial ensembles (CE) as the aggregation of multiple independent models with identical architectures, trained as a single model. We show that the optimization dynamics of CE simplify dramatically when the number of models in the ensemble is large, resembling the dynamics of wide models, yet scale much more favorably. We use recent theoretical results on the finite width corrections of the NTK to perform efficient architecture search in a space of finite width CE that aims to either minimize capacity, or maximize trainability under a set of constraints. The resulting ensembles can be efficiently implemented in practical architectures using group convolutions and block diagonal layers. Finally, we show how our framework can be used to analytically derive optimal group convolution modules originally found using expensive grid searches, without having to train a single model.

We introduce a methodology for efficient monitoring of processes running on hosts in a corporate network. The methodology is based on collecting streams of system calls produced by all or selected processes on the hosts, and sending them over the network to a monitoring server, where machine learning algorithms are used to identify changes in process behavior due to malicious activity, hardware failures, or software errors. The methodology uses a sequence of system call count vectors as the data format which can handle large and varying volumes of data. Unlike previous approaches, the methodology introduced in this paper is suitable for distributed collection and processing of data in large corporate networks. We evaluate the methodology both in a laboratory setting on a real-life setup and provide statistics characterizing performance and accuracy of the methodology., Comment: 5 pages, 4 figures, ICCST 2017

Progressive familial intrahepatic cholestasis (PFIC) is a lethal inherited childhood cholestasis of hepatocellular origin. Different subtypes of PFIC have been described according to serum gamma-glutamyl transpeptidase (GGT) activity. There is currently no effective medical therapy available for children with PFIC. We report on 39 patients with PFIC who received ursodeoxycholic acid (UDCA) orally (20-30 mg/kg b.w./day) for a period of 2 to 4 years. Group 1 (n = 26) consisted of children with normal GGT activity, and group 2 (n = 13) of children with high GGT activity. Within group 1, liver tests normalized in 11 children, improved in 5, and stabilized or worsened in 10. Within group 2, liver tests normalized in six children, improved in four, and stabilized or worsened in three. Improvement of parameters was associated with an enrichment of the circulating pool of bile acids with UDCA. Hepatosplenomegaly and pruritus disappeared or diminished in children in whom liver tests normalized. In nine of these children, liver tests worsened and normalized again after stopping and restarting UDCA. Liver histology assessed in four children after normalization of liver tests and 2 years of treatment showed a decrease in fibrosis. We conclude that UDCA should be considered in the initial therapeutic management of children with PFIC, because it appears effective in resolving or improving the liver function and the clinical status of a fair proportion of children. Chronic UDCA therapy might thus avoid the need for liver transplantation in some children with PFIC.
