William S. Cleveland - Shanti S. Gupta Professor of Statistics, Purdue University
Nov 24, 11:25am to 12:40pm
Applied Mathematics & Data Science - Colloquia - Hermann Hall, Armour Dining Room
Abstract: The widely used term "big data" carries with it a notion of computational performance for the analysis of big datasets. But for data analysis, computational performance depends very heavily not just on size but on the computational complexity of the analytic routines used in the analysis... read more

Tirthankar Dasgupta, Associate Professor - Department of Statistics, Harvard University
Nov 23, 4:40pm to 5:40pm
Department of Applied Mathematics - Colloquia - E1 258
In many modern-day social, educational and marketing experiments, multiple covariate measurements are available for each experimental unit. Whereas randomized treatment assignment balances observed and unobserved covariates “in expectation,” a single randomization may result in a highly imbalanced... read more

Hannah Albert, AMAT Ph.D. Candidate - IIT
Nov 18, 12:45pm to 1:40pm
Department of Applied Mathematics - Seminar - E1 025
The behavior of a stochastic differential equation, i.e., a differential equation with a noise component, can be analyzed by determining quantities such as: • mean exit time • escape probability • transition probability density function (found using the Fokker-Plank equation) When the noise... read more

Sou-Cheng Choi - Senior Statistician in NORC, University of Chicago, - Research Assistant Professor, Applied Mathematics, IIT
Nov 17, 11:25am to 12:40pm
Lulu Kang - Seminar - SB 220
Probabilistic record linkage (PRL) refers to the process of matching records from different data sources such as database tables with missing data in primary key. It can be applied to join or deduplicate records or to impute missing data, resulting in better data quality in any case. An important... read more

Martin Strauss - University of Michigan
Nov 16, 4:40pm to 5:40pm
Department of Applied Mathematics - Colloquia - E1 258
The Fourier Transform and its fast algorithms continue to be fundamentally useful in many areas of math, science, and technology. In one interpretation, the Fourier Transform takes the evaluations of a polynomial p at special points and finds the values of p's coefficients. The celebrated FFT... read more

Min Wu - Northwestern University, Department of Applied Mathematics
Nov 11, 12:45pm to 1:40pm
Department of Applied Mathematics - Seminar - E1 025
The mechanical behavior of soft biological tissues has received a considerable amount of attention in the last few years. In growth problems such as morphogenesis, wound healing, tumor growth, and so on, intermediate/final shapes and patterns are the results of the interaction relating the... read more

Andrew H. Suk, Assistant Professor, Department of Mathematics, Statsitics, and Computer Science - University of Illinois at Chicago
Nov 9, 4:40pm to 5:40pm
Department of Applied Mathematics - Colloquia - E1 258
Turan and Szemeredi-type theorems prove the existence of certain well-behaved patterns in dense graphs and hypergraphs. Here we show much stronger/larger patterns exist for graphs and hypergraphs that arise from geometry or algebra. The talk is based on recent joint works with Jacob Fox, Janos Pach... read more

Stephen Yau - Department of Mathematical Sciences, Tsinghua University, Beijing, China
Nov 6, 11:15am to 12:15pm
Department of Applied Mathematics - Colloquia - E1 102
What kinds of amino acid sequences could possibly be protein sequences? From all existing databases that we can find, known proteins are only a small fraction of all possible combinations of amino acids. Beginning with Sanger's first detailed determination of a protein sequence in 1952, previous... read more

Hualong Feng - Visiting Assistant Professor, - IIT
Nov 4, 12:45pm to 1:50pm
Department of Applied Mathematics - Seminar - E1 025
We demonstrate the ability to simulate complex flows of entangled polymers using a high-fidelity slip-link model. The macroscopic transport equations are solved using smoothed-particle hydrodynamics (SPH), while the stresses are calculated using stochastic simulation of an ensemble of polymer... read more

Nov 2, 4:40pm to 5:40pm
Department of Applied Mathematics - Colloquia - E1 258
I will discuss a general overview of the theory of stochastic homogenization for first- and second-order nonlinear partial differential equations.
