R-CTSVM+: Robust capped L1-norm twin support vector machine with privileged information In the learning using privileged information paradigm, it is the basic assumption that if a small loss in the correcting space on the privileged data can be obtained, then a small loss in the decision space...
To address this issue, we propose to develop a novel capped $\ell _p$-norm LDA model for robust dimension reduction against to outliers specifically. Proposed method integrates the capped $\ell _p$-norm based loss into the objective, which not only suppresses the light outliers but also ...
Although L1-norm based methods are more robust, they fail to obtain joint sparse projections which play a significant role in feature selection. To address this problem, Nie et al. [11] proposed robust feature selection (RFS). RFS employs an L2,1-norm based loss function as well as an L2...

The remarkably high numbers of wounds and viral load on scarred or infested developing honey bees may have caused significant weight loss and extensive injuries observed on the abdomen, wings, legs, proboscis and antennae of adult honey bees. Together, the survival of infested honey bees was ...
Moreover, SIVcpz Nef has acquired the ability to antagonize CPZ tetherin without the loss of anti- RCM tetherin activity, indicating that SIVcpz Nef has made the way through a gain-of-function evolution (Figure 4). To our knowledge, here we demonstrated that SIVcpz Nef is able to ...
a number of drawbacks are associated with these antibiotics which include toxicity, low stability,side effectslike mild nausea, vomiting, upset stomach,loss of appetite,headacheand hair loss. Another major issue is the bacterial resistance to existing antibiotics [4]. Therefore it is of outmost impo...
More precisely, we combined L1-norm with capped L1-norm to represent the amount of information extracted by the filter and control regularization. In the process of pruning, the insignificant filters remove directly without any loss in the test accuracy, providing much slimmer and compact models ...
