Deep learning based language models have improved generation-based linguistic steganography,posing a huge challenge for linguistic steganalysis. The existing neural-network-based linguistic steganalysis methods are incompetent to deal with complicated text because they only extract single-granularity features such as global or local text features. To fuse multi-granularity text features, we present a novel linguistic steganalysis method based on attentional bidirectional long-shortterm-memory(BiLSTM) and short-cut dense convolutional neural network(CNN). The BiLSTM equipped with the scaled dot-product attention mechanism is used to capture the long dependency representations of the input sentence. The CNN with the short-cut and dense connection is exploited to extract sufficient local semantic features from the word embedding matrix. We connect two structures in parallel, concatenate the long dependency representations and the local semantic features, and classify the stego and cover texts. The results of comparative experiments demonstrate that the proposed method is superior to the state-of-the-art linguistic steganalysis.

Systems Science and Systems Engineering 1996年第3期6卷 361-366页

作者： WANG Shilin(Institute of Systems Science, Academia Sinica, Beijing, 100080)xue yiming(Beijing Business College 100037, China)

This paper describes a new method which is different with the shadow price method to evaluate the economic benefits of the water source project. The approach is to take the water source as a constraint on the regional economic development, calculate the difference between the generaded when the water source project is in operation and the gross product generated when the project is nonexistent, and then review the economic benefits on the project. For this purpose, we have constructed an input-output linear programming model and compiled a compatible using the routines for solving the input-output linear programming model. The above models and the routines have been used in paractical calculation of economic benefits of a water source project for a region. The computation result are satisfactory.

中医各家学说课程的定义、定位及其与中医经典理论的关系,以及中医各家学说的地位、现状、学习研究的意义等,学术界一直有争议。以中医经典著作为支撑的中医理论形成之后,关键就是如何灵活应用共性理论解决临床实际问题,而历代名医就是活用理论的成功典范,是“知常达变”的集中代表。因而,中医各家学说具有与中医经典课程同样重要的地位,应当引起中医教育工作者足够的重视。
