comment:: (A Nonlocal)提出非对称非本地神经网络,包含非对称金字塔非本地块(APNB)和非对称融合非本地块(AFNB)。APNB可以减少运算量。AFNB融合不同级别的特征。 Why 卷积无法捕捉长距离依赖。nonlocal耗费计算资源。 What 只要key分支和value分支的尺寸一样,输出尺寸就不会变化。所以只要在key分支和value分支中只...
右侧的结构与传统的non-local模型有些不一样,首先对Key和Value的特征采用Sample操作将原始的N*C的矩阵进行了进一步的特征抽取,从而得到了C*S的特征矩阵,其中S<<N,所以该模型就大大减小了计算复和内存消耗。 但是由于作者将传统的non-local模型中的N经过Sample操作之后变成了较小的S,这样就不能捕捉到每个像素点之...
2 Asymmetric Non-local Neural Network 2-1 Asymmetric Pyramid Non-local Block (APNB) APNB将金字塔采样利用到non-local块中,在不牺牲性能的情况下大大降低了计算量和内存消耗, 2-2 Asymmetric Fusion Non-local Block (AFNB) AFNB由APNB改造而来,在充分考虑到远程依赖关系的情况下融合了不同级别的特征。
The non-local module works as a particularly useful technique for semantic\nsegmentation while criticized for its prohibitive computation and GPU memory\noccupation. In this paper, we present Asymmetric Non-local Neural Network to\nsemantic segmentation, which has two prominent components: Asymmetric ...
In this regard, the Gurtin-Murdoch theory (GMT) besides the nonlocal theory (NT) of continuum elasticity are recruited within the exponential shear bendable curved beam formulations to embrace the consequences of the surface Lame parameters along with the surface residual and nonlocal stresses. In ...
However, the existing local random walk link prediction algorithm simplifiy the definition of random walk process between nodes as symmetrical relationship, and ignore the influence of non-visible factors on the relationship of information diffusion between nodes. In this paper, for the first time, ...
which uses Structural Vector Autoregressive Model.The result shows that there exists significant regional non-symmetric effect on the effect of financial expenditures and tax income on outputs.The outputs of comprehensive economic zone on financial expenditures of impact response is positive,which on ...
In contrast, gene-copies displaying a reduction in the extent of local synteny relative to the ortholog may be predisposed to accelerated rates of sequence evolution and the resultant fates of neofunctionalization or nonfunctionalization. However, we find no evidence of an association between rate ...
Totally asymmetric simple exclusion processes (TASEP) with particles which occupy more than one lattice site and with a local inhomogeneity far away from the boundaries are investigated. These non-equilibrium processes are relevant for the understanding of many biological and chemical phenomena. The ...
The selected model-driven methods include Top-Hat10, Max-Median11, weighted strengthened local contrast measure (WSLCM)29, multiscale tri-layer local contrast measure (TLLCM)30, Infrared patch-image (IPI)15, non-convex rank approximation minimization (NRAM)31, Reweighted infrared patch-tensor (...
