Variance reduction in SGD by distributed importance sampling 4 dynamice sample weights by loss function engineering 通过对loss function的修改,可以更简单地对sample weights进行处理,例如最广为人知的focal loss。weighted loss function 就是通过在loss function计算的层面做加权从而实现样本层面加权的,只需要在每个...
Our results highlight the importance of identifying patient-specific DE genes, with its potential to provide clinically valuable insights into patient subgroups for applications in precision medicine.

In the branch at the bottom, we first perform the maximum pool and average pool operations [42] on the input feature X∈RC×H×W along the channel axis, concatenate the obtained results and send them to the 7×7 convolution layer and sigmoid to obtain the spatial importance weight Ws∈R1...
Fig. 7. Distribution of data in the training and testing sets. 3.2. Feature importance and feature engineering Feature importance can enhance the interpretability of the model (Zhou et al., 2021), and in addition, it is considered an effective tool for sensitivity analysis of geotechnical enginee...
ReLU.\(\lambda \)is set to 1. We implement the loss function as two loss layers in Caffe, with one loss layer focusing on the model regression accuracy and the other focusing on the performance loss on the training data. We train the network using standard SGD and batch normalization [...
Finally, according to the recorded coordinate data, the target area is cropped out in the original color sample image. The shorter side of the rectangle is symmetrically extended on both sides, transforming it into a square. It should be mentioned that, considering the importance of leaf edge ...
Furthermore, most methods do not consider the importance of background pseudo-change generation for improving the data diversity. In this paper, we introduce a novel multi-temporal sample pair generation technique called Image-level Sample Pair Generation (ISPG) to enhance the building change ...
We can consider the importance of the material in this book on many levels, but let's focus on three. First, consider your role as a business unit manager with people working under your supervision. Next, in the longer term, you probably have aspirations to become a senior executive with ...
