Sentiment analysis, also known as opinion mining, seeks to figure out points of view from documents. Sentiment classification is a specific task of sentiment analysis that divides documents into positive and negative sentiment polarities according to the attitudes expressed. Feature extraction is a significant part of sentiment classification. Traditional feature extraction methods mine statistical...
Lyrics are an important part of songs. Lyrics recognition is the basis of retrieving songs and recognizing the content of songs, which is of great value. At present, the research of speech recognition has made great progresses. But there are still difficulties in recognition of lyrics in songs with accompaniment. Related research is generally lacking, especially for Chinese lyrics in songs with accompaniment,...
This paper presents a novel classified method that is called extension genetic algorithm (EGA). The new method is a combination of extension theory and genetic algorithm (GA). In the past, we used the extension method in some clustered problems. With the method, we had to rely on experiences to set rules on classical domain and weight, which caused to increase two tedious and complicated steps in...
In this paper, a time-delay identification method for linear multi-input multi-output systems is proposed. Based on the existing research and improved on neural network time-delay identification method, an algorithm was applied to linear multivariable systems. By choosing proper criterion function, the system time-delay parameter could be estimated from the relationship between time-delay parameter...
