A/B tests (or "A/B/n tests") refer to the experiments and the corresponding inference on the treatment effect(s) of a two-level or multi-level controllable experimental factor. The common practice is to use a randomized design and perform hypothesis tests on the estimates. However, such estimations... read more

Gaussian process regression is a popular machine learning tool. But it is difficult to be applied to analyze large-scale experiment data with high dimension input (large $$p$$) and large sample size (large $$N$$). To overcome such issues, we propose a novel dimension reduction method that finds the... read more

Function approximation is relatively simple compared to many other continuous numerical problems, such as solving (stochastic and/or partial) differential equations. Interpolation is often used in the case of noiseless data, and regression can handle the case of noisy data. For functions of one... read more

College of Science, Applied Mathematics - Seminar - Rettaliata Engineering Center, Room 103
PDE and ODE are commonly used to describe a wide variety of physical phenomena such as sound, heat, diffusion, electrostatics, electrodynamics, fluid dynamics, elasticity, and quantum mechanics, etc. Discovering the governing equations from noisy data is an essential challenge in many areas of... read more

College of Science, Applied Mathematics - Seminar - Rettaliata Engineering Center, Room 103
Low rank representation for massive spatial data has become popular recently. Model cross covariance structure for multivariate spatial data can be challenging due to the non-negative definite restriction of the covariance function. The commonly used models, such as Linear model of... read more

College of Science, Applied Mathematics - Seminar - Rettaliata Engineering Center, Room 103
We introduce a new family of deep neural network models. Instead of specifying a discrete sequence of hidden layers, we parameterize the derivative of the hidden state using a neural network. The output of the network is computed using a black-box differential equation solver. These continuous-... read more

College of Science, Applied Mathematics - Seminar - Rettaliata Engineering Center, Room 103
During the past several years, our research group has constructed adaptive algorithms for integration, approximation, and optimization problems. Instead of relying on heuristic error estimates, these algorithms have rigorous justification. This talk highlights our approach.

A/B testing refers to the statistical procedure of conducting an experiment to compare two treatments, A and B, applied to different testing subjects. It is widely used by technology companies such as Facebook, LinkedIn, and Netflix, to compare different algorithms, web-designs, and other online... read more
