Title: Weakly Supervised Machine Learning for Knowledge Discovery from Unstructured Text

Slides | Video

Abstract: The real-world big data are largely dynamic, interconnected, and unstructured texts. It is important to transform such massive unstructured data into structured knowledge.  Many researchers rely on labor-intensive labeling and curation to extract knowledge from text data.   Such approaches, however, are not scalable.   We vision that massive text data itself may disclose a large body of hidden structures and knowledge.  Equipped with pretrained language models and machine learning methods, it is promising to transform unstructured data into structured knowledge.  In this talk, we overview a set of weakly supervised machine learning methods developed recently in our group for such an exploration, including joint spherical text embedding, discriminative topic mining, taxonomy construction, text classification, and taxonomy-guided text analysis. We show that weakly supervised approach could be promising at transforming massive text data into structured knowledge.

Title: Random Fuzzy Sets and Belief Functions: Application to Machine Learning

Slides | Video

Abstract: The theory of belief functions is a powerful formalism for uncertain reasoning, with many successful applications to knowledge representation, information fusion, and machine learning., Until now, however, most applications have been limited to problems (such as classification) in which the variables of interest take values in finite domains. Although belief functions can, in theory, be defined in infinite spaces, we lacked practical representations allowing us to manipulate and combine such belief functions. In this talk, I show that the theory of epistemic random fuzzy sets, an extension of Possibility and Dempster-Shafer theories, provides an appropriate framework for evidential reasoning in general spaces. In particular, I introduce Gaussian random fuzzy numbers and vectors, which generalize both Gaussian random variables and Gaussian possibility distributions. As an illustration, I show an application of this new formalism to nonlinear regression.
