RobustandFully-DynamicCoresetfor Continuous-and-BoundedLearning(WithOutliers) Problems

Neural Information Processing Systems

Moreover, our robust coreset can be efficiently maintained in fullydynamic environment. To the best of our knowledge, this is the first robust and fully-dynamic coreset construction method for these optimization problems.



UncertaintyAwareSemi-SupervisedLearningon GraphData

Neural Information Processing Systems

However,GNNs have notconsidered different types ofuncertainties associated with class probabilities to minimize risk of increasing misclassification under uncertainty in real life. In this work, we propose a multi-source uncertainty framework using a GNN that reflects various types of predictive uncertainties in both deep learning and belief/evidence theory domains fornodeclassification predictions.







OntheConvergenceofStepDecayStep-Sizefor StochasticOptimization

Neural Information Processing Systems

Step decay step-size schedules (constant and then cut) are widely used in practice because of their excellent convergence and generalization qualities, but their theoretical properties are not yet well understood. Weprovide convergence results for step decay in the non-convexregime, ensuring that the gradient norm vanishes at an O(lnT/ T)rate.
