This approach represents further proving of our previously introduced EKENS algorithm, where the critical stage of the estimation of the inverse of the nonlinearity is revised. The used of the Gram-Charlier series, makes the proposed algorithm capable of dealing with both nonlinear mappings and variations of statistical distributions of the sources.

The finite state model represents walking as a set of If-Then rules. An If-Then rule uses coded sensory information as inputs (If) and levels of electrical activities of muscles as outputs (Then). The model incorporates temporal and spatial synergies between muscle groups based on sensory information. The sensory input includes accelerations of leg and body segments, and ground reaction forces at toe and heel zones of the sole. The output of the rules is generated by detecting the onset of muscle activity from the amplified and rectified recordings of EMG signals from the prime movers of the leg. The coding uses a local threshold technique. Adaptive logic networks (ALNs) were used for estimation of If-Then rules. The training consisted of various samples of walking recorded in healthy individuals. The application of ALNs was optimized for low misclassification error and fast training. The overall performance of ALN (correct responses that would lead to correct stepping) when applied on test data, not used for the training, was >82%. We assumed that 80% is the margin for correct stepping for the walking in hemiplegic individuals","PeriodicalId":231606,"journal":{"name":"2006 8th Seminar on Neural Network Applications in Electrical Engineering","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124561558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
