Vishesh Karwa - Department of Statistics & Department of Computer Science, Harvard University
Feb 12, 2018 - 1:50pm to 2:55pm
Department of Applied Mathematics - Colloquia - Rettaliata Engineering Center, Room 104
Stochastic Block models (SBM) with unknown block structure are widely used to detect community structure in real world networks.  SBM comes in many variants, hence it is essential to evaluate the fit of these variants. Testing the goodness-of-fit of such models is a challenging task due to the... read more

Feb 8, 2018 - 1:50pm to 2:55pm
Department of Applied Mathematics - Colloquia - Robert A. Pritzker Science Center, Room 152
This talk describes a high order accurate method to calculate integrals over smooth surfaces with boundaries. Given data locations that are arbitrarily distributed over the surface, together with some functional description of the surface and its boundary, the algorithm produces matching quadrature... read more
Wei Wang - Professor, Department of Mathematics, Nanjing University, China
Feb 8, 2018 - 12:50pm to 1:50pm
Department of Applied Mathematics - Seminar - Rettaliata Engineering Center, Room 119
This talk introduce some effective modelling for some SPDEs with separated  time scales. First we consider SPDEs with slow-fast part and averaging method is applied to derive the averaged approximation model. Normal deviation is also considered and large deviations further confirms the... read more
