The visual scenes are composed of basic elements, such as objects, parts, and other semantic regions. It is well-acknowledged that humans perceive the world in a compositional and hierarchical way in which visual scenes are treated as a layout of distinct semantic objects/attributes/parts. Those separated objects/attributes/parts are linked together via different relationships, including visual relationships and semantic relationships. Particularly, the shared parts/attributes/objects of the visual concepts (object, visual relationships), are shared and thus transferable among different visual concepts. Humans can easily imagine a new composite concept from the shared parts of different concepts, while one of the important shortcomings of current deep neural networks is the compositional perception ability and thus it requires a large scale of data to optimize the deep neural networks. From the perspective of compositional perception, this thesis thinks one of the limitations of typical neural networks is that the factor representations of deep neural networks are not sharable and transferable among different concepts. Therefore, the thesis introduces various techniques, including compositional learning framework, compositional invariant learning, and BatchFormer module, to enable the factor representations of deep neural networks sharable and transferable among different concepts for hierarchical relationship exploration, involving human-object interaction, 3D human-object interaction and sample relationships.
