A New Algorithm for Discovery Maximal Frequent Itemsets Based on Binary Vector Sets

Abstract: Frequent itemset mining is a classic problem in datamining.However,most algorithms have to scan databases many times.This paper presents an algorithm that can find maximal frequent itemsets quickly.In this algorithm,each transaction is represented as a binary vector,so the task of discovering maximal frequent itemsets is turn to search frequent patterns in binary vector set.Furthermore,this algorithm can certify mining maximal frequent patterns with only one scan of original databases.Experiments verify the efficiency and advantages of the proposed algorithm.

Forensic Analyses Based on Predictive Coding

Abstract: Cybercrime is growing rampantly around the world, which has caused huge monetary damages in recent years. One of the major difficulties in cybercrime forensic analysis is to identify relevant digital evidence from a large amount of electronic documents. Traditional methods, such as manual inspection and keyword searching, are no longer effective both in terms of time and accuracy. In order to reduce the cost, save time and improve the accuracy of forensic investigation, the paper proposed a predictive coding scheme to study and identify relevant digital evidence. The experimental results show that the predictive coding based on semantic searching is feasible, and more efficient and accurate than the keyword searching.

The Tendency of the Economical Accommodation Policy in Our Country

Abstract: The economical house which has been implemented does not solve the low income accommodation. On the basis of analyzing and adopting foreign accommodation security system, this article points out that we should cancel the economical house and offer more inexpensively-renting houses to low income people.

Comparative Analysis of the Influencing Factors upon Urban and Rural Residents' Consumption in Our Country

Abstract: This paper established the co-integration equation and the ECM model to study the factors of residents' consumption demand in our country from the urban and rural comparative perspectiveThe article found that the impact of income levels on the consumption of the urban and rural residents is the greatestThe impact of income distribution and government expenditure on the consumption of urban and rural residents is almost the same in the absolute level,however the effects of both on the consumption of urban and rural residents were of significant differencesGovernment expenditure had a positive crowding-in effect on the consumption of urban residents,while it would have negative and the crowding-out effect on the consumption of rural residentsDespite the consumption of urban and rural residents and the gap of income distribution moving along the opposite direction,the consumption of rural residents reacted about the gap of income distribution to a greater extent

A VAD-Based Variable Order Affine Projection Algorithm for Acoustic Echo Cancellation

Abstract: This paper proposes a new variable order affine projection algorithm for acoustic echo cancellation. By exploiting an efficient voice activity detection technique, the proposed algorithm can distinguish the significant and insignificant input data periods. It can thus switch between the higher and lower algorithm orders in these two situations, respectively. Hence, input data reusing can enhance convergence with more input excitation and the computation cost can be saved when the input is relatively weak. Simulations results verify the effectiveness of the proposed algorithm.
