显然皮尔逊相关系数损失是有界的,\mathcal{L}_{CI}\in[0,2],这会带来更好的训练稳定性。并且优化这种损失函数等价于先做feature scaling (将特征向量高斯标准化)再计算MSE loss,即L_2(r_S^d,r_T^d)=2m\mathcal{L}_{CI}(r_S^d,r_T^d),m为特征向量长度。 基于相关系数损失的feature imitation缓解...
In subject area: Computer Science Feature scaling refers to the process of transforming the values of independent variables so that they have common characteristics, such as being within a certain range of values, having an average value of 0, and the same standard deviation. This is done to ...
Feature scaling: it make gradient descent run much faster and converge in a lot fewer other iterations. Bad cases: Good cases: We can speed up gradient descent by having each of our input values in roughly the same range. This is because θ will descend quickly on small ranges and slowly ...

Autoscaling of a grid of web and compute nodes on Azure. A script template will be offered to easily spin up a set of R Server VMs in Azure, configure them as a grid for operationalizing analytics and remote execution. This grid can be scaled up or down based on CPU usage. ...
Next (Scaling Sensor Data) the sensor data is standardized using the standard scaler Eqs. (1)–(3) within the first n cycles of each engine, where n is a user-defined parameter. In the proposed research the value of n was 10, this value is based on the assumption that the first 10...

The present study examines the role of feature selection methods in optimizing machine learning algorithms for predicting heart disease. The Cleveland Heart disease dataset with sixteen feature selection techniques in three categories of filter, wrapper,
对于x_r和x_t,Image Encoder将会输出「Patch-Level」的features z_r,z_t \in \mathbb{R}^{H \times W \times C}。 Matcher会通过计算两个特征Patch-wise的相似度来探索目标图像上参考Mask的最佳匹配区域。 「Correspondence Matrix」 \mathbf{S} \in \mathbb{R}^{HW \times HW}定义如下: (\mathbf{S...
When the user annotates an image, a circle with radius r is draw over the frame in the annotation tool, where r can be set by the user through the annotations option GUI. Such circles are then used to form the ground truth segmentation masks. Vision Tool as an annotation assistance tool...
