In this mechanism finger\u2019s movement is mostly performed for every day\u2019s task. It is well known that to capture such movement EEG or ECoG signals are used. In this order to find the patterns from these signals is important. The BCI competition 4 dataset 4 is one such standard dataset of ECoG signals for individual finger movement provided by University of Washington, USA. In this work, this dataset is, statistically analyzed to understand the nature of data and outliers in it. Effectiveness of pre-processing algorithm is then visualized. The cleaned dataset has dual polarity and gaussian distribution nature which makes Tanh activation function suitable for the neural network BC4D4 model. BC4D4 uses Convolutional neural network for feature extraction, dense neural network for pattern identification and incorporating dropout &amp; regularization making the proposed model more resilient. Our model outperforms the state of the art work on the dataset 4 achieving 0.85 correlation value that is 1.85X (Winner of BCI competition 4, 2012) &amp; 1.25X (Finger Flex model, 2022).<\/jats:p>","DOI":"10.1186\/s40708-025-00250-5","type":"journal-article","created":{"date-parts":[[2025,2,15]],"date-time":"2025-02-15T13:49:41Z","timestamp":1739627381000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Harnessing the synergy of statistics and deep learning for BCI competition 4 dataset 4: a novel approach"],"prefix":"10.1186","volume":"12","author":[{"given":"Gauttam","family":"Jangir","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nisheeth","family":"Joshi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gaurav","family":"Purohit","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2025,2,15]]},"reference":[{"issue":"1","key":"250_CR1","doi-asserted-by":"publisher","first-page":"527","DOI":"10.1007\/BF01797193","volume":"87","author":"H Berger","year":"1929","unstructured":"Berger H (1929) \u00dcber das Elektrenkephalogramm des Menschen.
