摘要：

The goal of this paper is to determine the object a person visually perceives by analyzing BOLD fMRI data. We use an fMRI dataset and analyze the effects of univariate and multivariate feature selection techniques. By performing dimensionality reduction with Principal Component Analysis (PCA), training with a Support Vector Classifier without a kernel and appropriate smoothing, we obtained a 93.16% accuracy: higher than the state of the art 92%.
