Greedy Bilateral (GreB) Paradigm for Largescale Matrix Completion, Robust PCA and Lowrank Approximation
Our paper “Greedy Bilateral Sketch, Completion and Smoothing” has been accepted by AISIATS 2013. Abstracts reads below, PDF is here, and code will be coming soon. Abstract: Recovering a large lowrank matrix from highly corrupted, incomplete or sparse outlier overwhelmed … Continue reading
Compressed Labeling: An important extension of Hamming Compressed Sensing; at NIPS now
We are just informed that our submission “Compressed Labeling (CL) on Distilled Labelsets (DL) for Multilabel Learning” is accepted by Machine Learning Journal (Springer). Online first PDF can be downloaded here. CL is an important application and extension of Hamming … Continue reading
SemiSoft GoDec: >4 times faster, autodetermined k
Here is a good news of GoDec (pertaining to our ICML 2011 paper): SemiSoft GoDec is released. Different from the ordinary GoDec which imposes hard threshholding to both the singular values of the lowrank part L and the entries of the … Continue reading
Hamming Compressed Sensingrecovering kbit quantization from 1bit measurements with linear noniterative algorithm
We developed a new compressed sensing type signal acquisition paradigm called “Hamming Compressed Sensing (HCS)” to recover signal’s kbit quantization rather than itself. Directly recovering quantization is much more preferred in practical digital systems. HCS provides a linear, noniterative quantization … Continue reading

News about GoDec code and ICML 2011 paper
We recently published a google site for Go Decomposition (GoDec), presented on ICML 2011. Now you can find all the available information and upcoming news about GoDec on http://sites.google.com/site/godecomposition On the new site, there are 3 resources about GoDec we … Continue reading
GoDec: Randomized Lowrank & Sparse Matrix Decomposition in Noisy Case
This paper is accepted by ICML 2011 for presentation. Now the final version is ready and can be downloaded from here GO. Abstract: Lowrank and sparse structures have been profoundly studied in matrix completion and compressed sensing. In this paper, we develop … Continue reading
Multilabel Learning via Structured Decomposition and Group Sparsity
This paper is now available on arxiv： http://arxiv.org/abs/1103.0102 In multilabel learning, each sample is associated with several labels. Existing works indicate that exploring correlations between labels improve the prediction performance. However, embedding the label correlations into the training process significantly … Continue reading
Compressed sensing review (1): Reconstruction Algorithms
CS reconstruction algorithms are always the most astonishing thing for people who know compressed sensing at the first time. Because only a few sampling (much less than ShannonNyquist sampling rate) can perfectly reconstruct the whole signal is really a big … Continue reading
Compressed sensing review (0)
I plan to write an easy understanding review of compressed sensing, which is a popular topic that attracts considerable attention from 2004 and appears being related to more and more fields in recent years. The review will be posted in … Continue reading
Compressed sensing games
Compressed sensing has been proved having intimate connections to tremendous problems in signal processing and harmonic analysis. The fundamental idea of compressed sensing and its extension matrix completion can be illustrated as: It is possible to recover a signal (e.g., … Continue reading
