The quality of fMRI data is best among other modalities such as Electroencephalography (EEG) and Magnetoencephalography (MEG). In fMRI, normally number of features are more than the number of instances so it is necessary to select the features and do dimension reduction to remove noisy and redundant data. Many techniques and methods are used to select the significant features (voxels). In this paper, the significant voxels are selected within the anatomical region of interest (ROI) based on the absolute values. In this study, we have predicted the brain states using two machine learning algorithm, i.e, Radial basis function (RBF) network and Naïve Bayes. A visual experiment with two categories is done. In conclusion, it is shown that less number of voxels and specific brain regions can increase the accuracy of prediction. © 2016 IEEE. date: 2016 publisher: Institute of Electrical and Electronics Engineers Inc. official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84985022960&doi=10.1109%2fMeMeA.2016.7533739&partnerID=40&md5=97c1725380c32a7ad17082732529c5ad id_number: 10.1109/MeMeA.2016.7533739 full_text_status: none publication: 2016 IEEE International Symposium on Medical Measurements and Applications, MeMeA 2016 - Proceedings refereed: TRUE isbn: 9781467391726 citation: Zafar, R. and Malik, A.S. and Kamel, N. and Dass, S.C.
