Efficient keyword spotting system for information retrieval by LUO Jun, OU Zhi-jian

“…A new two-stage keyword spotting system was proposed based on syllable graph for audio information retrieval task,which could efficiently spot the interesting words in mass speech data,thus serve for the national security.It comprised two stages – preprocessing and searching.In the preprocessing stage,the audio data was recognized into syllable graph which included high accuracy syllable candidates,and unsupervised MLLR（maximum likelihood linear regression） adaptation was carried out iteratively to further improve the accuracy of the syllable graph.In the searching stage,to answer the frequent queries from users,searching for matched keywords was only scanned in the graph for likely syllable strings.A forward-backward algorithm based on syllable N-grammar was used to calculate confidence measures for further filtering of the searching result.Experimental results show the system achieved good performances in both recall rate and accuracy rate,and in the searching stage only 0.01 times of real time is needed,which can meet the demand for fast retrieval.…”

Partial fanout multicast switching model of reconfigurable foundation network by Bo ZHANG, Bin-qiang WANG, Sheng-ping ZHU

“…The multicast switching model using copying before scheduling and fanout copying modes had worse large-scale extensibility capability in traditional technology system.A partial fanout multicast switching model with basic switching fabric comprised by 2×2 Boolean cells and Boolean group concentrators was proposed facing to reconfigurable foundation network.Self-routing path selected was realized by partial fanout copying mode and quaternary symbols cut-through coding.Unicast blocking probability,multicast blocking probability and multicast fanout ratio iterative course was deduced based on unicast and multicast mixed business source.The simulation result shows that the value of multicast blocking probability is from 10^-10 to 10^-2 based on Bernoulli uniform business source when normalized unicast load 0.2,the model can meet time QoS requirement because the value of multicast time delay is less than hundred nano-second level limit.…”

“…Aimed at the problems of the signaling cost and power consumption in the power control measurement of the millimeter wave system, as well as the complexity caused by iteration operations, a millimeter wave link power allocation prediction algorithm using the Sub-6 GHz frequency band was proposed.Firstly, the mapping between the Sub-6 GHz band channel information and the optimal power allocation of the millimeter wave band was analyzed.Then, a deep neural network (DNN) model was utilized to realize this mapping function.To predict the power allocation of millimeter wave channel with Sub-6 GHz channel as input, the neural network was trained with the weighted mean square error minimization method (WMMSE) as the supervisor in different scenarios.The simulation results show that compared with the WMMSE algorithm in millimeter wave band, the proposed algorithm can obtain more than 97% of its sum-rate performance while taking less than 0.1% of the time.…”

Nettree for maximum disjoint paths with length constraint in DAG by Yan LI, You-xi WU, Chun-ping HUANG, Zhi-ying ZHANG, Zhen-xiang ZENG

“…The problem of the maximum disjoint paths in directed acyclic graphs(DAG)was researched which is to find the maximum disjoint paths with length k between two given vertices.A greedy algorithm named greedy path(GP)was proposed to solve the problem.GP transformed a DAG into a nettree with depth k+1 at first.Then the number of root-leaf paths for each node of the nettree was calculated to achieve the number of total paths for each vertex of the DAG.In order to obtain an optimized disjoint path,GP selected the node in the(k+1)th level of the nettree as the current node,and searched for the optimized parent in the usable parents whose number of total paths was minimal.This process was iterated,until there was no disjoint path.The space and time complexities of GP are O(wkn(p+q))and O(kn(p+q)+n²).To evaluate the performance of GP,an algorithm which can create artificial DAG with known maximum disjoint paths was also proposed.Experimental results show that GP can get better performance than other competitive algorithms.…”

High-precision indoor fast positioning algorithm based on carrier phase by Shaoshuai FAN, Zhiqiang RONG, Hui TIAN, Lihua LI

“…In order to improve the positioning accuracy and the speed of position solution in indoor wireless environment, a high-precision indoor fast positioning algorithm based on carrier phase was proposed.By introducing the reference terminal, the influence of clock error between devices on the accuracy of the positioning algorithm was completely eliminated by using the double difference between the carrier phase measurements of the terminal to be positioned and the reference terminal.Taking advantage of the invariability of integer ambiguity during the phase-locked loop lock-off, an iterative integer ambiguity resolution algorithm based on multi-time point measurement data was designed, and the fast integer ambiguity resolution was realized.After the integer ambiguity was solved, the terminal to be located could be located with high precision by using accurate carrier phase difference measurement.The simulation results show that the positioning algorithm proposed can completely overcome the influence of clock error on positioning performance, and can achieve centimeter-level positioning accuracy at very few sampling time points.…”
