Due to the development of numerous biomedical information sensing devices, such as Photoacoustic Tomography, Computed Tomography (CT), Optical Microscopy and Tomography, Single Photon Emission Computed Tomography (SPECT), Magnetic Resonance (MR) Imaging, Ultrasound, Positron Emission Tomography (PET), Magnetic Particle Imaging, EE/MEG, Electron Tomography and Atomic Force Microscopy, etc. a lot of biomedical information has been gathered these years. In order to process the data, many advanced methods like deep learning were proposed for data analysis, data mining, data tracing and so on because of the excellent performance.
However, a lot of issues appeared in obtaining and processing such big biomedical data, such as data heterogeneity, data missing, data imbalance and high dimensionality of data etc. Moreover, many biomedical datasets simultaneously contain multiple above issues. However, most of the current techniques can only deal with homogeneous, complete, and moderate sized-dimensional data, which
makes the learning of big biomedical data difficult.
Therefore, data processing such as data representation learning, dimensionality reduction, missing value imputation should be developed to bridge the big gap to make the deep learning methods useful for practical applications.
