We investigate a family of update methods for online machine learning algorithms for cost-sensitive multiclass and structured classification problems. The update rules are based on multinomial logistic models. The most interesting question for such an approach is how to integrate the cost function into the learning paradigm. We propose a number of solutions to this problem. To demonstrate the app

Popular Abstract in Swedish Under evolutionens gång har ett komplext system utvecklats för att hålla blodets kalkhalt konstant. Bisköldkörtelhormonet intar här en central roll. Sänkning av blodets kalkhalt ger upphov till ökad bisköldkörtelhormonsekretion. Bisköldkörtelhormonet påverkar njurar och skelett så att mer kalk återförs till blodbanan. Bisköldkörtelhormonet stimulerar också njurarna tillCalcium homeostasis after thyroid surgery was studied during the immediate postoperative period and after one year. One day after hemithyroidectomy ionised calcium decreased whereas basal PTH did not change. EDTA stimulated maximal and total PTH secretion and set-point decreased on postoperative day 1 and normalised on day 7. One year after hemithyroidectomy (n=10) total calcium and 1.25(OH)2D3 de

I artikeln belyses den svenska kvinnans situation över tid: forntid, dåtid och nutid, varvid en analys av hennes position görs från ett rättssociologiskt perspektiv när det gäller "inter-system", "intra-system", de "ekonomiska", "politiska", "naturliga" och "sociala" systemen.

In this paper the magnetization of a ferro-or ferri-magnetic material has been modeled with the Landau-Lifshitz-Gilbert (LLG) equation. We show that with the aid of a static magnetic bias field the material can be switched between a Lorentz-like material with a resonance frequency and a material exhibiting a magnetic conductivity. The reflection from a magnetic material backed by a perfect electri

To develop PDT beyond treatment of thin superficial tumors, to also be an efficient treatment alternative to deeply located and/or thick tumors, a system based on interstitial illumination using multiple fibers has been developed. Conditions that could benefit from such a treatment modality are for instance malignant brain tumors and tumors in the oral cavity. In interstitial PDT one needs to use

This paper is a part of a doctoral study named “Leadership in a crisis”. This paper proposes a way to a) measure the human talent leadership and b) training the ability for leadership, regarding individuals as well as leadership teams. The same simulation should be used for measuring and training. The simulation system uses intelligent agents based on HLA, IEEE 1516, for easy scaling, interoperabi
