Latest Patents

Zerhouni holds a patent titled "Simultaneous feature extraction and dictionary learning using deep learning architectures for characterization of images of heterogeneous tissue samples." This patent describes apparatuses, methods, and computer-readable media that facilitate simultaneous feature extraction and dictionary learning from heterogeneous tissue images without the need for prior local labeling. The invention utilizes a convolutional autoencoder that is adapted and enhanced to jointly learn a feature extraction algorithm and a dictionary of representative atoms. During the training of the autoencoder, an image patch is tiled into sub-patches, retaining only the highest activation value per sub-patch. This method ensures that only a subset of spatially constrained values per patch is used for reconstruction. The deconvolutional filters serve as the dictionary elements, with a deconvolution layer dedicated to these elements. The embodiments described in this patent may be utilized in models that represent local tissue heterogeneity, thereby improving the understanding of disease progression and aiding in the treatment, diagnosis, and prediction of various medical conditions, including cancer.
