In the past decade, the synthesis-based methods have drawn people's attention more and more in the sparse representation community. The synthesis model decomposes the data into a combination of a few atoms of the overcomplete dictionary. However, the dual analysis-based methods have not been studied deeply. The analysis model results in a sparse outcome by multiplying an analysis dictionary. This...
A pressure-pained-detector for trigeminal neuralgia based on MSP430 ultra low-power MCU is described. According to the characteristic of human trigeminal neuralgia, an excellent pressure-pained-detector is designed. A high precision medical pressure sensor is used to get pressure-pain signal, and it can convert the pressure signal to a tiny voltage signal. The multi-sensor information fusion technology...
This paper presents a new keyword extraction algorithm for Chinese news Web pages using lexical chains and word co-occurrence combined with frequency features, cohesion features, and corelation features. A lexical chain is an external performance consistency by semantically related words of a text, and is the representation of the semantic content of a portion of the text. Word co-occurrence distribution...
