Abstract

The invention relates to a building indoor learning efficiency detection method and system. The method comprises the following steps: S1, acquiring electroencephalogram signal data; S2, preprocessingthe acquired electroencephalogram signal data; S3, extracting energy features of the preprocessed electroencephalogram signals under different electrode channels through features; and S4, taking the energy features under corresponding electrode channels of the feature extraction as input features, and inputting the input features into a BP neural network to realize classification of learning attention. Energy features of the electroencephalogram signals under different electrode channels are extracted through features, and are taken as input features of a subsequent classifier, and the attention state of a learner is accurately reflected; accurate classification of electroencephalogram signals is realized; and accurate, stable and reliable measurement of the concentration degree of the attention electroencephalogram signals is realized, and wide influence is generated on attention action mechanisms in human brains in psychology and neurophysiology.

Description

technical field [0001] The invention relates to the technical field of learning attention EEG signal classification, in particular to a method and system for detecting learning efficiency in a building. Background technique [0002] In the journey of scientific research, human beings have never stopped studying themselves. The 21st century is the era of biological science and brain science. Multi-level comprehensive research on advanced cognitive functions such as human brain thinking, learning, language and attention has become one of the popular directions of contemporary scientific development. way to grow rapidly. Because of its unique properties, the EEG signals collected from the human scalp have increasingly become an indispensable experimental and analytical method in this type of research. Therefore, the analysis and processing of EEG signals has become an indispensable part of brain science research. It has also become an important method to study learners' atten...
