Embodiment 1

[0052] Such as figure 1 As shown, this embodiment is an emotion recognition method based on a deep fuzzy forest, which mainly includes the steps of music emotion EEG data collection, EEG signal preprocessing, and deep fuzzy forest music emotion recognition. Among them, the music EEG data collection is through the establishment of the EEG music emotion experiment. Firstly, a quiet and insufficiently lit experimental environment is selected, and then the subjects are divided into two parts. One half is used to select experimental materials, and the other half is tested to obtain EEG data based on musical emotion. The EEG signal preprocessing process includes three parts: filtering, segmentation and screening samples. Deep fuzzy forest emotion recognition is the process of classifying music EEG data, including two processes of multi-granularity scanning to extract features and cascading forest emotion recognition.

Abstract

The invention relates to an emotion recognition method based on a deep fuzzy forest. The method comprises the following steps: S1, collecting electroencephalogram signals; S2, preprocessing the electroencephalogram signals to remove noise; S3, inputting the electroencephalogram signals into a pre-trained deep fuzzy forest model to obtain an emotion recognition result. In the step S3, multi-granularity scanning is adopted for the deep fuzzy forest model, and probability vectors of electroencephalogram signal features are obtained from the electroencephalogram signals to serve as input of a cascade forest; and a cascade forest is adopted to recognize the probability vectors of the electroencephalogram signal features to obtain an emotion recognition result, and the multi-granularity scanningand the cascade forest are both constructed by adopting a fuzzy decision tree. Compared with the prior art, the emotion recognition method combines a fuzzy set theory with a traditional decision treelearning strategy, and has the advantages of originality, high recognition degree, few parameters, capability of being used for a small sample data set, accurate and reliable result and the like.

Description

technical field [0001] The invention relates to the field of emotion recognition, in particular to an emotion recognition method based on a deep fuzzy forest. Background technique [0002] With the development of science and technology, people's lives are becoming more and more enriched, and the integration of interdisciplinary knowledge and technology has made the research methods of psychological related diseases more and more diversified. Emotion is a kind of psychological state produced by integrating people's feelings, thoughts and desires. It is ubiquitous in people's daily life, work and study. Bad emotions will affect our physical health and mood. Cause depression, anxiety, etc., and have a major impact on interpersonal communication. In the research and treatment of these diseases, music has also played an increasingly important role, and now a special discipline of "music therapy" has been formed. The so-called "music therapy" is to study the influence of music o...
