Unsupervised AI and mass-spectroscopy: new paper on Expert Systems with Applications

MALDI mass-spectroscopy is a interesting experimental technique that, in a nutshell, breaks down an organic sample into small voxels and, for each voxel, it determines its spectral footprint. In general, given the same tipe of tissue, benign and malignant cells tend to yield different spectra. Since several thousands of spectra can be generated by a …

New paper: unsupervised learning for medical images analysis

We recently published a new paper on Journal of Supercomputing. The article focuses on an approach that combines automatic feature extraction and unsupervised learning for the analysis of medical images. The idea is to extract (long) vectors of Haralick features for each pixel, and use that information to train a Self-Organizing Map: similar pixels will …
