Inspired by natural immune systems, Artificial Immune System (AIS) is an emerging kind of computational intelligence paradigm. The traditional immune algorithm and Ai-net for clustering still have the problems of training time-consumption and accuracy. In this paper, AIS Algorithm is improved with Quantum Mechanics theory and the Schro??dinger equation to add the idea of the energy level into the...
This paper proposes a novel algorithm, named pseudo-inverse locality preserving projections (PLPP), for dimensionality reduction involving undersampled problems. This algorithm considers the matrix singularity caused by undersampled problems by substituting the Moore-Penrose pseudo-inverse for the inverse of the matrix. Under the pseudo-inverse form eigenequation, the optimal locality preserving projections...
In a group signature scheme, a group member signs messages anonymously on behalf of the group. However, in the case of a dispute, the actual group signer's identity can be revealed by a designated entity. In this paper, we propose a new identity-based group signature scheme using bilinear maps. The group signature scheme is well suited for large groups, i. e., the length of the group' s public key...
Recently Cash, Kiltz and Shoup [5] proposed a new computational problem called twin Diffie-Hellman problem. This paper investigates properties of the trapdoor test introduced in [5]. Secondly this paper presents some new relations between the twin Diffie-Hellman problem and the Diffie-Hellman problem.
A tool, called ARDK (augmented reality development kit), which has more advantages than former tools of this kind, is developed and represented in this paper. The advantages over others are as follows: without setting internal parameters of camera ahead of time, ARDK allows the system to automatically compute them at the real-time during the operating. It also solves the problem of being unable to...
