In this paper, we address the preparation of ecological datasets for data mining. We propose a new adaptive method for automatic dataset construction using Erblet transform, which can be seen as a non-uniform filter bank where the center frequency and the bandwidth of each filter match the ERB (Equivalent Rectangular Bandwidth) scale, followed by data quality assessment using a tonality index (TI)...
An in-depth investigation is made on the optimization goal most concerned about device maintenance time and additional cost caused by maintenance scheduling. Based on the above, a new model for distribution maintenance scheduling is developed with multipurpose and multiple constraints. In addition, the merits of ant colony algorithm are parallel search and strong optimization capabilities, which was...
Researches on PMSM servo system based on internal module and robust 2-DOF control structure are discussed in this essay, setting up a math model for PMSM servo system controller, and this system is simulated by means of MATLAB/Simulink.
This paper introduces a query-specific opinion summarization system: QOS. When input an opinion question, the system returns a summary with relevance to the opinions and target described by the question. The system has several modules to be able to do this: a question analysis and query reformulation module, a latent semantic indexing based sentence scoring module, a sentence polarity detection module,...
