Transformation invariant sparse coding

2011 IEEE International Workshop on Machine Learning for Signal Processing, 2011
Sparse coding is a well established principle for unsupervised learning. Traditionally, features are extracted in sparse coding in specific locations, however, often we would prefer invariant representation. This paper introduces a general transformation invariant sparse coding (TISC) model.

Compressed Nonnegative Sparse Coding

2010 IEEE International Conference on Data Mining, 2010
Sparse Coding (SC), which models the data vectors as sparse linear combinations over basis vectors, has been widely applied in machine learning, signal processing and neuroscience. In this paper, we propose a dual random projection method to provide an efficient solution to Nonnegative Sparse Coding (NSC) using small memory.

Supervised Transfer Sparse Coding

Proceedings of the AAAI Conference on Artificial Intelligence, 2014
A combination of the sparse coding and transfer learning techniques was shown to be accurate and robust in classification tasks where training and testing objects have a shared feature space but are sampled from different underlying distributions, i.e., belong to different domains. The key assumption in such case is that in spite of the
