Label-Noise robust logistic regression and its applications
Jakramate Bootkrajang,Ata Kaban +1 more
TL;DR: A label-noise robust version of the logistic regression and multinomiallogistic regression classifiers is considered and a novel sparsity-promoting regularisation approach is developed which allows us to tackle challenging high dimensional noisy settings.

Multitask Sparse Nonnegative Matrix Factorization for Joint Spectral–Spatial Hyperspectral Imagery Denoising
Minchao Ye,Yuntao Qian,Jun Zhou +2 more
TL;DR: This paper proposes to solve the HSI denoising problem by sparse nonnegative matrix factorization (SNMF), which is an integrated model that combines parts-based dictionary learning and sparse coding, and shows that MTSNMF has superior performance on both synthetic and real-world data compared with several otherDenoising methods.
Proceedings ArticleDOI
Transfer learning to predict missing ratings via heterogeneous user feedbacks
TL;DR: This paper explores how to use the binary preference data expressed in the form of like/dislike to help reduce the impact of data sparsity of more expressive numerical ratings.
