Abstract

The invention discloses an electroencephalogram signal recognition fuzzy system and method with the transfer learning ability. In a traditional intelligent recognition method, a training set and a testing set of a model are assumed to conform to the same data distribution, and therefore the good classification performance can be obtained only when data in a training domain and data in a testing domain conform to the same distribution. The electroencephalogram signal recognition fuzzy method helps epileptic electroencephalogram signal recognition under the transfer learning environment by means of the transfer learning strategy. The 0-order TSK type fuzzy system modeling technology with the direct-pushing type transfer learning ability is built based on the fuzzy system. The technology has the transfer learning ability and is not confined to the assumption of the uniform data distribution of the training domain and the testing domain, a certain difference is allowed to exist between the data in the training domain and the data in the testing domain, the good performance is kept on the condition of the same data distribution of the training domain and the testing domain, and the recognition effect of the finally-obtained model under the diversified electroencephalogram signal recognition problems is greatly improved.

Description

technical field [0001] The invention belongs to the field of signal recognition and application, in particular to a fuzzy-system EEG signal recognition method with transfer learning capability. Background technique [0002] Epilepsy is a transient brain dysfunction caused by sudden abnormalities of brain neurons. About 80% of epilepsy patients have certain EEG abnormalities. Among the main intelligent identification methods at present, the fuzzy system shows unique advantages compared with other main intelligent identification methods because of its good explainability and strong learning ability. For example, the fuzzy system expert knowledge rule base constructed for epilepsy can provide empirical knowledge for doctors' future diagnosis. [0003] Although the fuzzy system has shown some effectiveness in EEG signal recognition, this technique assumes that the training set and test set of the model obey the same data distribution, so it can only be obtained when the traini...
