The existing typical combined query image retrieval methods adopt Euclidean distance as sample distance measurement method, and the model trained by triple loss function blindly pursues absolute distance between samples, resulting in unsatisfactory image retrieval performance. Meanwhile, these methods ...
The generated sql is sql for adding new fields or sql for updating comments .In order to avoid data loss, there will be no sql for deleting fields.It is more convenient for daily use to divide the operation of generating sql and executing sql into two parts.You can quickly get the sql...
To take full advantage of it, methods should be linked to an inferential goal via a loss function. For example, in the two﹕tage, compound sampling model the posterior means are optimal under squared error loss. However, they can perform poorly in estimating the histogram of the parameters ...
In these cases, the total acquisition time is limited to less than 1/(2JCC) to avoid resolution of the scalar coupling and loss of sensitivity. The effect of the coupling can be eliminated by multiplication of the interferogram by the function cos−1(πJCCt1) or cos−1(πJCCt2) as ...
Since only one value of the j component in \(y_{i,j}\) is 1, the loss function can be expressed as the sum of the corresponding probabilities of M relation truth labels. And since we use a masking mechanism for the FC fully connected layer, i.e., an all-zero mask for FC input...
SSIM loss function and target edge-enhancement loss are also introduced to improve the quality of the fused image. Compared with existing state-of-the-art fusion methods on public datasets, it is demonstrated that our model has a better performance on quantitative metrics and qualitative effects....
To that end we introduce a new loss function that exploits the relations within the triplets. We compare our approach to recently introduced MatchNet and DeepCompare and demonstrate the advantages of our descriptor in terms of performance, memory footprint and speed i.e. when run in GPU, the ...
Age-related loss of noradrenergic neurons in the brains of triple trans- genic mice. Age Pub Online, http://dx.doi.org/10.1007/s11357-011-9343-0.Manaye, K. F., Mouton, P. R., Xu, G., Drew, A., Lei, D. L., Sharma, Y., et al. (2013). Age-related loss of noradrenergic...
This paper reviews when to consider PAM4 and duobinary formats, as the modulation scheme which yields the highest system margins at a given data rate is a function of the channel loss profile. A 20Gb/s triple-mode transmitter capable of efficiently implementing these three common modulation ...
A contrast loss function is leveraged to train the multiscale decomposition network for enhancing the complementarity of information at different scales. Moreover, a compensatory loss is introduced to train the efficient IRCAFN, aiming to balance the distinguishing information between infrared and visible...
