Improvements are still required because it is difficult to reduce tremors without impairing voluntary movement. So, in this study, a novel proposed method is used to classify the types of tremors. First, pre-processing is used to remove undesirable noise from the input signals using digital band pass filter (DBPF), Savitzky Golay digital FIR filter (SGDFF), and adaptive wavelet transform (AWT) approaches. Then, the pre-processed signals are fed into the dual attention-based dense capsule bidirectional gated recurrent unit (DA_DCBiGRU) model. A dense capsule is used to extract features, dual attention is utilized to reduce dimensionality, and BiGRU is used to identify tremor kinds such as resting, postural, and action. Finally, the suggested classifier\u2019s efficiency is increased by fine-tuning the parameters with the improved fire hawk optimizer (IFHO). When compared to other existing approaches, the Python tool\u2019s performance measurements indicate the greatest accuracy rate of 98.2%.<\/jats:p>","DOI":"10.1142\/s021946782750015x","type":"journal-article","created":{"date-parts":[[2024,12,31]],"date-time":"2024-12-31T03:07:03Z","timestamp":1735614423000},"source":"Crossref","is-referenced-by-count":0,"title":["Dual Attention\u2013Based Dense Capsule Bidirectional Gated Recurrent Unit for Classifying Tremor Types in Parkinson\u2019s Disease\u2013Affected Patients"],"prefix":"10.1142","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-2509-5077","authenticated-orcid":false,"given":"Sk.","family":"Wasim Akram","sequence":"first","affiliation":[{"name":"Department of Computer Science and Engineering, Vasireddy Venkatadri Institute of Technology, Namburu Guntur-522508, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5966-5400","authenticated-orcid":false,"given":"A.
