摘要： A preparation method of Antrodia cinnamomea water-insoluble dietary fiber. After ethanol and water extraction, Antrodia cinnamomea wastes are dried and superfine-comminuted to obtain Antrodia cinnamomea waste powder. The waste powder treated with NaOH solution containing NaBH4 is extracted it twice to obtain two extracts. The two extracts are combined and an appropriate amount of glacial acetic acid are added for neutralization. The extracts are centrifugalized and precipitate is collected. After washing the precipitate with ultrapure water, the precipitate is dissolved with LiCl-DMSO. The precipitate that is insoluble in the LiCl-DMSO solution is dialyzed and freeze-dried to obtain the water-insoluble dietary fiber component ACA-IDK of Antrodia cinnamomea. The LiCl-DMSO solution is subjected to ethanol/DMSO fractional precipitation, and then the precipitate is collected and dialyzed. The water-insoluble dietary fiber component ACA-DK of Antrodia cinnamomea is obtained after freeze-drying.

摘要： The invention relates to an adversarial optimization method for the training process of generative adversarial network. According to the adversarial optimization method for the training process of generative adversarial network, the optimal transmission problem is transformed into solving the elliptic Monge-Ampere partial differential equation (MAPDE) in the generator G. To solve MAPDE of n (n>3) dimensions, the Neumann boundary conditions are improved and the discretization of MAPDE is extended to obtain the optimal mapping between a generator and a discriminator, which constitutes the adversarial network MAGAN. In the process of training the defence network, by overcoming the loss function of the optimal mapping, the defence network can obtain a maximum distance between the two measurements and obtain filtered security samples. The effective attack method of GANs is successfully established, with the precision improved by 5.3%. In addition, the MAGAN can be stably trained without adjusting hyper-parameters, so that the accuracy of target classification and recognition system for unmanned vehicle can be well improved.
