To reach this goal, we design a deep CNN network with a multi-task loss, i.e., one is for discriminating face and non-face, and another is for face box regression.
We use a multi-task loss function L: Lleft p,u,{t}^u,vright)={L}_{mathrm{cls}}left p,uright)+lambda left[uge 1right]{L}_{mathrm{loc}}left {t}^u,vright), (7 where Lcls p, u) = − log p u is the log loss of the real category u.
Our contributions are: (i) a CNN architecture that predicts multiple gradings at once, and we propose variants of the architecture including using 3D convolutions; (ii) showing that this architecture can be trained using a multi-task loss function without requiring segmentation level annotation; and (iii) a localization method that clearly shows pathological regions in the disc volumes.
Arnaud Montebourg, who calls for "deglobalisation", has been given an impossible task (stopping industrial job losses) to go with a ridiculous title ("minister of productive recovery").The question is what Mr Hollande will do with his untrammelled power.
CHANGED FOR GOOD Radical transformation efforts inside big companies fail for any number of reasons, among them insufficient resources devoted to the task, a loss of interest by the chief executive or naysayers who are allowed to stay in place.
(3) we define a task specific loss function for our customized structured SVM.
However, since originally the methods were not developed for this task, their loss functions do not directly link to the criteria used in the evaluation of ranking.
129 A similar opposing effect was observed on a gambling task where loss aversion was insensitive to dopaminergic medication, but risk taking to gain prospects was selectively heightened in the group with impulsive disorders.
In fact, it can be shown that their results hold for any loss-based model fitting task, provided a loss function that exhibits certain mathematical properties (see section 3 and Supplementary Material).
The worst, he warned, is yet to come -- when people are left with the quiet, terrible task of facing loss alone.
He last spoke, a fortnight before his death, when he took Cameron to task over the loss of 100 jobs at Sheffield Forgemasters.
