Julien Mairal  SoftwareSPAMSSPAMS is an optimization toolbox implementing algorithms to address various machine learning and signal processing problems involving dictionary learning and matrix factorization (e.g., NMF, sparse PCA); solving mediumscale sparse decomposition problems with LARS, coordinate descent, OMP, SOMP, proximal methods; solving largescale sparse estimation problems with stochastic optimization; solving structured sparse decomposition problems (e.g., sparse group lasso, treestructured regularization, structured sparsity with overlapping groups). FlipFlopFlipFlop is an opensource software, implementing a fast method for de novo transcript discovery and abundance estimation from RNASeq data. It differs from classical approaches such as Cufflinks by simultaneously performing the identification and quantitation tasks using a penalized maximum likelihood approach, which leads to improved precision recall. Other software taking this approach have an exponential complexity in the number of exons of a gene. We use a novel algorithm based on network flow formalism, which gives us a polynomial runtime. In practice, FlipFlop was shown to outperform penalized maximum likelihood based software in terms of speed, and to perform transcript discovery in less than 1/2 second for large genes. FlipFlop 1.0.0 is a user friendly bioconductor R package. It is freely available on the Bioconductor website. MODLThis is the opensource software package corresponding to the ICML’16 paper “Dictionary Learning for Massive Matrix Factorization” for hugescale matrix factorization. The package is written and maintained by Arthur Mensch (Inria). This is a highly optimized library that is able to handle matrices of several terabytes on a single workstation. CKNThis is the opensource software package corresponding to the paper “Convolutional kernel networks” published at NIPS’14. We are going to release soon a new GPU implementation corresponding to the NIPS’16 paper “Endtoend kernel learning with supervised convolutional kernel networks”. PatchCKNThis is the software package and the new dataset “RomePatches” corresponding to the IJCV paper “Convolutional Patch Representations for Image Retrieval: an Unsupervised Approach”. DolphinThis is the opensource software package corresponding to the paper IEEETSP paper “DOLPHInDictionary Learning for Phase Retrieval”. The package is written and maintained by Andreas Tillmann (TU Darmstadt). Misc
