§ Fuzziness as coarsening not at random
Statistical modeling of fuzziness as an informative coarsening mechanism induced by the data-measurement process.
§ Fuzziness-induced information loss in statistical inference
Formal assessment of how fuzzy-valued observations affect estimation, uncertainty quantification, and inferential efficiency.
§ Bayesian PCP-inspired models for text mining
Bayesian formulations of low-rank and sparse matrix decomposition, inspired by principal component pursuit, for text denoising, topic-quality assessment, keyword extraction, and semantic structure recovery in sparse document-term data.
§ Fuzzy topic models for short texts
Topic models for short and sparse texts, with fuzziness used to represent partial thematic membership and semantic uncertainty.
