In many real-world topic detection tasks, the process of the topic detection is often interactive, which means the users are likely to interfere the reason process by expressing their preferences. We proposed an algorithm, iOLDA, and the software framework for interactive topic evolution pattern detection based on Latent Dirichlet Allocation (LDA). To abate(More)
— Ensuring high quality of service (QoS) of multicast video stream over a next generation network is a challenging issue, and how to implement the wire-speed multicast with hardware logical support in the network nodes of every hierarchy is a key solution to achieve high QoS multicast. Currently, the multicast packets are processed in this way, in which(More)
The microbial transformation of a series of tetrahydroprotoberberines (THPBs, 1–5) by Gliocladium deliquescens NRRL1086 was investigated. In this research, the novel glycosylation of tetrahydroberberrubine (1) was observed with fast rate and high regio- and enantio-selectivity. One pair of unique enantiomorphic alkaloidal glycosides T-1 and T-2 was isolated(More)
