Self-designed hierarchical network based hand shape intelligent recognition and evaluation for Chinese zither performing

A proper hand shape is the foundation for professional musical instrument performance. In this paper, the image recognition technology based on artificial intelligence is introduced into the hand shape recognition of performing Chinese zither, which is referred to as Zheng in Chinese, for the first time to realize the function of hand shape intelligent evaluation and the self-designed hierarchical network is proposed to recognize and evaluate correct hand shape for Zheng performing. The intra-class difference is larger than the inter-class difference for Zheng performing hand shape image, which belongs to fine-grained image. Therefore, we use the first layer network to determine four classes of images acquired from different viewpoints. Meanwhile, the feature maps from different convolutional blocks of this layer are concatenated as the input of the second layer, which performs fine classification of Zheng performing hand shape images. Consequently, the learning ability of the network can be improved and the complexity of the network can be reduced at the same time. We design an experimental paradigm for instrumentalist hand shape performance evaluation, formulate a Zheng hand shape evaluation merit based on image recognition, and construct a Chinese zither hand shape Dataset (CZ-dataset V3) for the real scene. The experiments show that the method proposed in this paper can effectively improve the recognition accuracy of fine-grained hand shape images and the result is consistent with the evaluation of professional advisors, which realizes the perfect combination of the intelligent image recognition and the hand shape evaluation for Chinese traditional instrument performing.

On the semi-convergence of preconditioned GLHSS iteration method for non-Hermitian singular saddle point problem

Recently, Fan and Zheng studied the preconditioned generalized local Hermitian and skew-Hermitian splitting (GLHSS) iteration method for non-Hermitian singular saddle point problem, and given its semi-convergence conditions; see Fan and Zheng (2014). In this note, we prove the semi-convergence of preconditioned GLHSS method by another method. The obtained result shows that the conditions for guaranteeing its semi-convergence are easy to check and more weaker.

Knowledge and data co-driven intelligent assessment of Chinese zither fingerings

The intelligent assessment of musical instrument fingerings can provide learners with timely feedback to greatly improve learning efficiency and lay the foundation for distance teaching. This paper first proposes knowledge and data dual-driven evaluation solution for Chinese zither (Zheng) fingerings, to the best of our knowledge, by integrating the Zheng professional knowledge, fingering video data and intelligent assessment methods. Firstly, we design an experimental paradigm and formulate an assessment scale to ensure the professionalism and intelligence of fingering evaluation. Moreover, due to the lack of musical instrument fingering datasets, a basic fingering dataset with interpretability is established for the zither right hand (CF-Dataset). In order to analyze the fingering movement more, this paper finally proposes a fingering assessment method based on Zheng prior knowledge. The experimental results show that the pipeline designed in this paper is feasible and effective, which makes a pioneering exploration for the combination of musical instrument professional fingering and intelligent video assessment.     

A provably secure and efficient two‐party password‐based explicit authenticated key exchange protocol resistance to password guessing attacks

Password‐based two‐party authenticated key exchange (2PAKE) protocol enables two or more entities, who only share a low‐entropy password between them, to authenticate each other and establish a high‐entropy secret session key. Recently, Zheng et al. proposed a password‐based 2PAKE protocol based on bilinear pairings and claimed that their protocol is secure against the known security attacks. However, in this paper, we indicate that the protocol of Zheng et al. is insecure against the off‐line password guessing attack, which is a serious threat to such protocols. Consequently, we show that an attacker who obtained the users' password by applying the off‐line password guessing attack can easily obtain the secret session key. In addition, the protocol of Zheng et al. does not provide the forward secrecy of the session key. As a remedy, we also improve the protocol of Zheng et al. and prove the security of our enhanced protocol in the random oracle model. The simulation result shows that the execution time of our 2PAKE protocol is less compared with other existing protocols. Copyright © 2015 John Wiley & Sons, Ltd.
