Speech Title: The Long March of Theoretical Exploration of Boosting
Abstract: AdaBoost is a famous mainstream ensemble learning approach that has greatly influenced machine learning and related areas. A fundamentally fascinating mystery of Adaboost lies in the phenomenon that it seems resistant to overfitting, which has inspired a lot of theoretical investigations. In this talk, we will briefly introduce the long history of learning theory studies and debates about Boosting, where the recently concluding result discloses the importance of minimizing margin variance when maximizing margin mean during learning process, which provides new inspiration for the design of powerful learning algorithms such as ODMs (Optimal margin Distribution Machines).

Speech Title: Concept Drift Detection, Understanding and Adaptation
Abstract: Concept drift is known as an unforeseeable change in underlying streaming data distribution over time. The phenomenon of concept drift has been recognized as the root cause of decreased effectiveness in many decision-related applications. A promising solution for coping with persistent environmental change and avoiding system performance degradation is to build a detection and adaptive system. This talk will present a set of methods and algorithms that can effectively and accurately detect understand and adapt concept drift. The main contents include (1) two novel competence models to indirectly measure variations in data distribution through changes in competence. By detecting changes in competence, differences in data distribution can be accurately detected and quantified, then further described in unstructured data streams; (2) algorithms for determining a drift region to identify when and where a concept drift takes place in a data stream, and a local drift degree measurement that can continuously monitor regional density changes. (3) a fuzzy adaptive regression approach to dynamically recognize, train, and store patterns. The approach assigns the membership degree of the upcoming examples belonging to these patterns to identify which pattern the current examples belong to during the modelling process. The new algorithms and techniques can be applied to data-driven prediction in complex real-world environments.

Speech Title: Automated Machine Learning
Abstract: Automated machine learning (AutoML) aims to automatically construct machine learning solutions from data. In this talk, we discuss several different applications of AutoML, from the learning of entity/relation embeddings in knowledge graphs, to the design of sample selection schedules for robust learning from noisy labels, and to the search for data-specific deep networks in neural architecture search. By carefully designing the underlying search space and efficient solvers for the resultant optimization problems, we demonstrate the effectiveness of AutoML in all these different scenarios, and that the searched embedding/schedule/neural architecture can significantly outperform the manually designed counterparts.

Speech Title: Robust Rank Aggregation and Its Application
Abstract: In rank aggregation (RA), a collection of preferences from different users are summarized into a total order under the assumption of homogeneity of users. Model misspecification in RA arises since the homogeneity assumption fails to be satisfied in the complex real-world situation. Existing robust RAs usually resort to an augmentation of the ranking model to account for additional noises, where the collected preferences can be treated as a noisy perturbation of idealized preferences. Since the majority of robust RAs rely on certain perturbation assumptions, they cannot generalize well to agnostic noise-corrupted preferences in the real world. In this talk, I first summarize the literature of Robust RA methods, and I present CoarsenRank, which possesses robustness against model misspecification. Specifically, the properties of our CoarsenRank are summarized as follows: (1) CoarsenRank is designed for mild model misspecification, which assumes there exist the ideal preferences (consistent with model assumption) that locate in a neighborhood of the actual preferences. (2) CoarsenRank then performs regular RAs over a neighborhood of the preferences instead of the original data set directly. Therefore, CoarsenRank enjoys robustness against model misspecification within a neighborhood. (3) The neighborhood of the data set is defined via their empirical data distributions. (4) CoarsenRank is further instantiated to Coarsened Thurstone, Coarsened Bradly-Terry, and Coarsened Plackett-Luce with three popular probability ranking models. Meanwhile, tractable optimization strategies are introduced with regards to each instantiation respectively. Finally, I present the applications of RAs in Neuroscience, Deep Generative Models, and Contrastive learning.
