New social, economic, cultural, and technological trends bring new challenges to designers, and the use of data intelligence analytics is a very promising way to improve the efficiency and quality of their results. In this paper, we use convolutional neural networks to improve and optimize the GAN model, resulting in a more stable DCGAN network model. Visual innovation-related features are inputted into the discriminator in the DCGAN model, and creative visual images are automatically generated in the generator under the constraint label restriction. The network parameters of the DCGAN model are optimized through the training process to construct the brand image design process of automated visual creativity. The performance test analysis of the DCGAN model reveals that the analysis results of its IS index and FID index values are much higher than those of the WGAN and CGAN models, indicating that the generated visual creative images have high quality. The analysis of the visual creativity of the designed brand image found that the subjects’ favorability of the brand image intended by the DCGAN model reached 3.57 points on average and brought a visual feast to the subjects. This paper provides support for the application of Generative Adversarial Networks in the field of brand image design and achieves automated brand creative image design.

SiOC-based ceramics are considered promising electromagnetic wave-absorbing materials because of their lightweight, high-temperature resistance, and heat insulation properties. Herein, SiOC@C ceramic nanospheres were prepared using a liquid phase method combined with the polymer-derived ceramics (PDCs) method, followed by heat treatment in N2 and Ar atmospheres at different temperatures. The morphology, microstructure, phase composition, and electromagnetic wave absorption performance of the SiOC@C ceramic nanospheres were investigated in detail. The SiOC@C ceramic nanospheres obtained in the Ar atmosphere showed an RLmin of -67.03 dB; whereas the SiOC@C ceramic nanospheres obtained in the N2 atmosphere exhibited an RLmin value of -63.76 dB. The outstanding electromagnetic wave absorption performance of the SiOC@C ceramic nanospheres was attributed to the synergistic effect between conductive loss, interfacial/defect polarization loss, multiple reflections and scattering.Therefore, this research provides valuable insights into the design and fabrication of SiOC ceramic-based electromagnetic wave absorbers.
