[Retracted] Identifying Animals in Camera Trap Images via Neural Architecture Search

Figure 5

A shallow regression tree. A regression tree is a stack of binary trees which conduct condition evaluations at nodes. A leaf node corresponds to a possible prediction yielded by the regression tree. A leaf node can be reached by walking along a path from the root to the leaf, and the “walk” means the input satisfies all conditions of nodes along the path. In this figure, different kinds of nodes are represented by rectangles painted by different colours, e.g., nodes involving and are, respectively, denoted by red and blue rectangles, and the leaf nodes are represented by green nodes. The path between two nodes is denoted by arrows labelled “True” or “False”.
