That is that information processing of neural networks is viewed as the composition of the two steps: field organization and field action, in which, field organization transformation converts input pattern into relevant structure representation, extracting the underlying architecture features and forms a architecture representation in action transformation space; The field action transformation converts the features representation into expected output. In strategies, we use the dual affine coordinates in dual flat manifold as way of representation of field organization system and field action system, which established a theoretical framework of analysis the coupling mechanism of information processing from the view of point of structure representation and model generation.

Results show that when the thickness is less than 0.7 nm, Si3N4, normally amorphous in deposition state, could form a NaCl-type pseduocrystal structure due to the template effect of TiN crystal layer. Crystallized Si3N4 layers and TiN template layers grow coherently into columnar crystals with (111) preferred orientation. Correspondingly, the hardness of the films was enhanced to a maxim value of 38.5 GPa, showing a superhardness effect.
