A Dependence Stability Bound based on the VC Dimension for Relational Classification
Xing Wang,Hui He,Bin-Xing Fang,Hong-Li Zhang 보안공학연구지원센터 2015 International Journal of Database Theory and Appli Vol.8 No.3
Relational classification (RC) is concerned with the application of statistical learning to relational data. RC models do not have improved stability to smooth the perturbations generated by variations in the correlation between the relational data. Therefore, few studies have attempted to derive a bound and develop a stability learning framework for RC models. To solve this problem, we derive a learning bound with a new measure dependence stability and a limited Vapnik–Chervonenkis (VC) dimension. Based on the learning bound, we then design a stable learning framework that serves as a guideline for the development of new learning algorithms for a broad class of RC models. Applying a Markov logic network on synthesized and real-world datasets, our experimental results demonstrate that our bound can be tight if the RC model has appropriate dependence stability and limited VC dimension and our learning framework increases the stability of RC models while reducing the deviation between empirical risk and true risk.
Memory Nonfragile Output Feedback Robust MPC for Polytopic Timedelayed Systems with Constraints
Xing He,Wei Jiang,Caisheng Jiang 제어·로봇·시스템학회 2022 International Journal of Control, Automation, and Vol.20 No.2
This paper investigates memory nonfragile mixed-objective output feedback robust model predictive control (OFRMPC) for a class of uncertain systems subjected to physical constraint, bounded disturbance, unmeasurable delayed state and possible controller fragility. By employing a delay-independent Lyapunov-Krasovskii function and linear matrix inequality (LMI) framework, novel sufficient conditions for the proposed memory nonfragile OFRMPC are derived to asymptomatically stabilize the closed-loop system with guaranteed H∞/H2 performance for all admissible polytopic uncertainties, external disturbance, state delay, and additive or multiplicative gain perturbation. A key technique for this controller is the online optimization of an infinite-horizon objective function followed by a memory output feedback control law based on the pre-specified offline state estimator using modified quadratic bounded conditions. Moreover, the input constraint and the recursive feasibility have been further guaranteed via additional LMI-based conditions. Finally, a numerical example is given to illustrate the effectiveness of the proposed OFRMPC approach.
Mining Frequent Sub-hypergraph in an Uncertain Hypergraph for Knowledge Transfer
Xing Wang,Bin-Xing Fang,Hui He,Hong-Li Zhang 보안공학연구지원센터 2015 International Journal of Database Theory and Appli Vol.8 No.4
The knowledge transfer learning can generalize across domains where the types of objects and variables are different. Previous studies ignored connectivity and creativity of domain knowledge. Thus, these studies just transfer knowledge from a source domain to a target domain that not effectively use the knowledge from other domains. We proposed a method, called Multi-domain second order knowledge integration (MSKI), for integrating to address this problem. We hybridize and create new knowledge, which is formalized into an uncertain hypergraph. Then, we proposed a method to mine frequent sub-hypergraph from the uncertain hypergraph (MFS-UHG). The frequent sub-hypergraphs are pivot knowledge, which has to be transferred with high priority. We embed the pivot knowledge in the progress of MLN structure learning. The experimental evaluation on four domain datasets shows that the MSKI outperforms state-of-the-art MLN-based transfer learning.

Xing, T.X.,He, D.Y.,He, L.H.,Zhou, W.J.,Liao, X.L.,Chen, H.P. Asian Australasian Association of Animal Productio 1992 Animal Bioscience Vol.5 No.4
Three goats were fed with $^{15}N$-labelled rice straw to study the characteristics of digestion, assimilation, metabolism and excretion of C and N compounds from rice straw. It was shown that the amount of $^{15}N$ assimilated into the bodies of the two slaughtered goats accounted for 38.5 and 23.6% of the total amount of $^{15}N$ ingestion in the experimental diet by each goat. The $^{15}N$ excreted via the feces and urine for the three goats accounted for 34.8, 33.2 and 33.9% of the total amount of $^{15}N$ ingested in the feed of the 3 goats. The recoveries of $^{15}N$ from the two slaughtered goats were 73.3 and 57.5%, with the corresponding rates of $^{15}N$ loss 26.7 and 42.5% respectively. The amino acids digestibilities were 68.7 and 54.0%, while the digestibilities of carbohydrates were 74.8 and 67.7% respectively for goats 1 and 3.

In this study, surface molecularly imprinted polymers were synthesized with the metal-organic framework NH2-MIL-53 as carrier and naringenin as alternative template of Ochratoxin A (OTA). The amino groups on the surface of NH2-MIL- 53 reacted with the epoxy groups in glycidyl methacrylate (GMA). Subsequently, the double bonds of the GMA grafting on the surface of the material were used for polymerization to prepare the surface molecularly imprinted polymers. The obtained polymers were characterized by scanning electron microscope, transmission electron microscope, energy spectrometer, Fourier infrared spectrometer, X-ray diffraction, and laser particle size analyzer. Synthetic polymer was combined with solid phase extraction for separation and enrichment of trace OTA in grains. The spiked recoveries were found to be 78.95-106.45%, with relative standard deviations ranging from 5.16% to 6.31%. The detection limit and the quantification limit of the method were 0.04 μg·kg-1 and 0.12 μg·kg-1, respectively. Comparing the pretreatment effects of the self-made cartridge and the immunoaffinity column on the OTA in the sample, it showed that the self-made column had excellent performance and provided a new pretreatment method for the treatment of OTA in grains.

Bacillus subtilis XF-1, a strain with demonstrated ability to control clubroot disease caused by Plasmodiophora brassicae, was studied to elucidate its mechanism of antifungal activity against P. brassicae. Fengycin-type cyclopeptides (FTCPs), a well-known class of compounds with strong fungitoxic activity, were purified by acid precipitation, methanol extraction, and chromatographic separation. Eight homologs of fengycin, seven homologs of dehydroxyfengycin, and six unknown FTCPs were characterized with LC/ESI-MS, LC/ESI-MS/MS, and NMR. FTCPs (250μg/ml) were used to treat the resting spores of P. brassicae (107/ml) by detecting leakage of the cytoplasm components and cell destruction. After 12 h treatment, the absorbencies at 260 nm (A260) and at 280 nm (A280) increased gradually to approaching the maximum of absorbance, accompanying the collapse of P. brassicae resting spores, and nearly no complete cells were observed at 24 h treatment. The results suggested that the cells could be cleaved by the FTCPs of B. subtilis XF-1, and the diversity of FTCPs was mainly attributed to a mechanism of clubroot disease biocontrol.

Sea sand vanadia-titania magnetite is difficult to pelletize, and it is difficult for iron and steel enterprises touse it as a raw material for ironmaking. In this paper, the high-temperature physicochemical characteristics and sinteringbehavior of sea sand vanadia-titania magnetite were comprehensively studied and systematically evaluated. Thehigh-temperature metallurgical physicochemical characteristics of different iron ore powders and under different experimentalconditions were studied by the micro-sintering experimental system. The high-temperature sintering indexeswere comprehensively evaluated by the grey correlation analysis, and the influence of sea sand ore on sintering performancewas investigated by sintering pot experiment. The research results show that the high-temperature sinteringcharacteristics of sea sand vanadia-titania magnetite were the worst, and the grey correlation degree was the lowest. The high-temperature sintering characteristics of sintered blocks with sea sand ore were affected by changing the basicityand the addition amount of sea sand ore. When the basicity was 0.8 and the addition amount of sea sand ore was15 wt%, the evaluation index of grey relational analysis was the best. The vertical sintering speed and tumble indexwere slightly reduced by adding sea sand ore, but the sinter yield was improved and the particle size distribution of sinterwas optimized. The experimental results provide a certain data reference for the actual production of sinter with seasand vanadia-titania magnetite.
