Revised algorithm for online learning with kernels (OLK) in classification and regression is proposed in a reproducing kernel hilbert space (RKHS). Compared with the original OLK, the revised algorithm allows that the new data points arrive either one by one or two by two.
This paper starting from the teacher assessment data, analyze whether the evaluation indicators are suitable for factor analysis, then find the two factors which played a decisive role in evaluation indicators these indicators were interactive and related, so as to achieve the purpose of simplifying calculation. Final get the teachers' rankings by factor analysis.
The Voronoi diagram is the one of most fundamentals in computation geometry. The coverage control, especially the barrier coverage, will benefit from this diagram. Using the Voronoi diagram, the coverage holes can be detected in short time. In the lax demands which only include the influence of two neighbor sensors, the minimal exposure track based on the Voronoi can approach the optimal. But, because...
The computation temporal logic (CTL) is introduced to Signed Directed Graph (SDG) and a modeling and verifying method via Symbolic Model Checking is presented. The requirements and constrains of SDG are specified firstly, and the properties related to the fault propagation are extended, then the correctness properties of SDG are defined by CTL. Finally SDG is transferred into the SMV module through...
Multi-nexthop routing mechanisms is the key point in network congestion, and the essential question is how to forward packets among multi-nexthop to reach equiponderant forwarding. This paper proposes an equiponderant forwarding strategy in multi-nexthop routing, which forwards the packets according to the actual capability of each node, and resolves the equiponderant forwarding problem of multi-nexthop...
Source address authentication is very important to change current serious network security situation. In this article, we propose a new source address validation scheme based on IBS algorithm and study its security using SVO logic. We find that our scheme can successfully guarantees authenticity of IP packetpsilas information source.
Research on the good and bad points of fuzzy theory and neural network technology in fault diagnosis. Combine them in this paper with the method connected. Firstly using fuzzy method to process the information, and then diagnosis of the faults with neural networks approaching ability. Construct inference system to solve complicated faults happened in gasoline engine with this method. The results of...
Passport is a new secure and adoptable source address validation technique, which has attracted fully attention. In this article, we research into the efficiency of Passport. First of all, we build a mathematical model to describe Passportpsilas function, then propose an evaluating indexes, at last we use Brite generate a Power-Law network topology and design correlative algorithm to quantitative...
In this paper, an on-line signature verification system exploiting local and global information using two-stage fusion is presented. At the first stage, global information is extracted as 13-dimensional vector and recognized by majority classifiers, and then local information is extracted as time functions of various dynamic properties and recognized by BP neural network classifier. By fusing global...
