Early growth response 1 (Egr-1) is a cellular transcription factor involved in diverse biologic functions. Egr-1 has been associated with Epstein-Barr virus (EBV) infection, but it is still unknown whether any EBV protein regulates Egr-1 expression. In this study, we first showed that EBV reactivation is involved in upregulation of Egr-1 and that Egr-1 can(More)
Mood classification of music is an emerging field of music information retrieval. In the approach presented here features extracted from an audio file are used to map a song onto a psychologically based emotion space. The motivation behind this system is the lack of intuitive and contextually aware playlist generation tools available to music listeners. The(More)
In this paper, we proposed a weighted discrete K-nearest neighbor (weighted D-KNN) classification algorithm for detecting and evaluating emotion from Mandarin speech. In the experiments of the emotion recognition, Mandarin emotional speech database used contains five basic emotions, including anger, happiness, sadness, boredom and neutral, and the extracted(More)
Automatic emotional speech recognition system can be characterized by the selected features, the investigated emotional categories, the methods to collect speech utterances, the languages, and the type of classifier used in the experiments. Until now, several classifiers are adopted independently and tested on numerous emotional speech corpora but no any(More)
Emotions play a significant role in decision-making, healthy, perception, human interaction and human intelligence. Automatic recognition of emotion in speech is very desirable because it adds to the human- computer interaction and becomes an important research area in the last years. However, to the best of our knowledge, no works have focused on automatic(More)
Automatic recognition of emotions in speech aims at building classifiers for classifying emotions in test emotional speech. This paper presents an emotion recognition system to compare several classifiers from clean and noisy speech. Five emotions, including anger, happiness, sadness, neutral and boredom, from Mandarin emotional speech are investigated. The(More)
