Combine or Concatenate encoded attribute features?

[Starry-lei]

Hi, I find it is a combination, not the concatenation illustrated on paper, right?

if self.seperate_all:
x_class = self.class_embedf(x[:, self.bbox_dim:self.bbox_dim+self.class_dim, :])
if self.objectness_dim >0:
x_object = self.objectness_embedf(x[:, self.bbox_dim+self.class_dim:self.bbox_dim+self.class_dim+self.objectness_dim, :])
else:
x_object = 0

        if self.objfeat_dim > 0:
            x_objfeat = self.objfeat_embedf(x[:, self.bbox_dim+self.class_dim+self.objectness_dim:self.bbox_dim+self.class_dim+self.objectness_dim+self.objfeat_dim, :])
        else:
            x_objfeat = 0
            
        x_bbox = self.bbox_embedf(x[:, 0:self.bbox_dim, :])
        x = x_class + x_bbox + x_object + x_objfeat
