It is established that a space X with exponential \\(\\kappa\\) -domination has density not exceeding \\(\\kappa\\) if \\(l(X) \\leq\\kappa\\) and \\(t(X) \\leq\\kappa\\) . We also introduce a weaker property called exponential \\(\\kappa\\) - density and show that ...

Density maps 生成的密度地图,即公式\ref{eq00}和\ref{eq01},具有三个明显的缺点。首先,当高斯核较小时,密度地图集中在单个像素周围。结果是模型中的监督信息过少,难以学习有效信息。其次,如果高斯核较大,密度地图上的密集细胞区域难以区分,梯度信息也不明显。这阻碍了模型有效地学习位置信息,如图\ref{fig2}所示...
