1. Sparse Approximation of Spatial Channel Model with Dictionary Learning
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In large antenna systems, traditional channel estimation is costly and infeasible in some situations. Compressive sensing was proposed to estimate the channel with fewer measurements. Most of the previous work uses a predefined discrete Fourier transform matrix or overcomplete Fourier transform matrix to approximate the channel. READ MORE

3. A Novel Shoeprint Enhancement method for Forensic Evidence Using Sparse Representation method.
University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandlingAbstract : Shoeprints are often recovered at crime scenes and are the most abundant form of evidence at a crime scene, and in some cases, it is proved to be as accurate as fingerprints. The basis for shoeprint impression evidence is determining the source of a shoeprint impression recovered from a crime scene. READ MORE

4. Semantic Segmentation : Using Convolutional Neural Networks and Sparse dictionaries
University essay from Linköpings universitet/DatorseendeAbstract : The two main bottlenecks using deep neural networks are data dependency and training time. This thesis proposes a novel method for weight initialization of the convolutional layers in a convolutional neural network. This thesis introduces the usage of sparse dictionaries. READ MORE
