Naive Bayes is a probability-based classification method which is based on the assumption that attributes are conditionally mutually independent given the class label. Much research has been focused on improving the accuracy of Naïve Bayes via eager learning. In this paper, we propose a novel lazy learning algorithm, Selective Neighbourhood based Naïve(More)
Concept lattice model, the core structure in Formal Concept Analysis, has been successfully applied in software engineering and knowledge discovery. In this paper, we integrate the simple base classifier (Naïve Bayes or Nearest Neighbor) into each node of the concept lattice to form a new composite classifier. We develop two new classification systems, CLNB(More)
MOTIVATION Protein complexes are of great importance for unraveling the secrets of cellular organization and function. The AP-MS technique has provided an effective high-throughput screening to directly measure the co-complex relationship among multiple proteins, but its performance suffers from both false positives and false negatives. To computationally(More)
The automatic recognition of sound events by computers is an important aspect of emerging applications such as automated surveillance, machine hearing and auditory scene understanding. Recent advances in machine learning, as well as in computational models of the human auditory system, have contributed to advances in this increasingly popular research(More)
With the increasing availability of diverse biological information for proteins, integration of heterogeneous data becomes more useful for many problems in proteomics, such as annotating protein functions, predicting novel protein-protein interactions and so on. In this paper, we present an integrative approach called InteHC (Integrative Hierarchical(More)
A strain of Klebsiella sp. BK-58 that produces cis-epoxysuccinate was screened and identified. This novel enzyme hydrolyzes cis-epoxysuccinate to l(+)-tartaric acid and was purified to homogeneity. Its molecular mass was 30.1 kDa determined by MALDI–TOF–MS analysis. It was stable up to 50 °C and from pH 5 to 11 with optima at 50 °C and pH 8.5. The enzyme(More)
The gene encoding a novel cis-epoxysuccinate hydrolase, which hydrolyzes cis-epoxysuccinate to l (+)-tartaric acid, was cloned from Klebsiella sp. BK-58 and expressed in Escherichia coli. The ORF was 825 bp encoding a mature protein of 274 amino acids with a molecular mass of 30.1 kDa. Multiple sequence alignment showed that the enzyme belonged to the(More)
