AIM Seminar: Data analytics for neurodynamics and quantitative neuroimaging
Speaker: Sri Srinivas (Physics, NU) Abstract: We are exploring the eye-brain connection using visual evoked potentials. We have developed a new portable system combining a smart phone headset with a scalp sensor that measures potentials and electric fields on the scalp. This system is now in clinical tests in patients with macular degeneration and amblyopia, as well as providing new insights into the neuro-visual pathways and processing in the human…
AIM Seminar: Fast and Interpretable Tensor Methods for Spatiotemporal Analysis
Speaker: Rose Yu (Khoury, NU) Abstract: Multivariate spatiotemporal data is ubiquitous in science and engineering, from sports analytics to neuroscience. Such data can be naturally represented as a multiway tensor. Tensor latent factor models provide a powerful tool for reducing the dimensionality and discovering the higher-order latent structures from data. However, existing tensor models are often slow or fail to yield latent factors that are easy to interpret by domain…
AIM Seminar: Deep Decoder: Concise Image Representations from Untrained Networks
Speaker: Paul Hand (Math & Khoury, NU) Abstract: Deep neural networks have become highly effective tools for compression and image recovery tasks. This success can be attributed in part to their ability to represent and generate natural images well. Contrary to classical tools such as wavelets, image-generating deep neural networks have a large number of parameters and need to be trained on large datasets. We will discuss an untrained simple…
AIM Seminar: Easy, hard or convex?: the role of sparsity and structure in systems theory
Speaker: Mario Sznaier (EECE, NU) Abstract: Arguably, one of the hardest challenges faced now by the systems community stems from the exponential explosion in the availability of data, fueled by recent advances in sensing and actuation capabilities. Simply stated, classical techniques are ill equipped to handle very large volumes of (heterogeneous) data, due to poor scaling properties, and to impose the structural constraints required to implement ubiquitous sensing and control.…
AIM Seminar: Quantum state transfer – using magnetic fields
Speaker: Gabor Lippner (Math, NU) Abstract: Lossless transmission of quantum information through a network of particles is an important task in quantum computing. Mathematically this amounts to studying solutions of the discrete Schrödinger equation d/dt phi = i H phi, where H is typically the adjacency or Laplace matrix of the graph. This in turn leads to questions about subtle number-theoretic behavior of the eigenvalues of H. It has proven…
Compactifications, Configurations, and Cohomology
This conference aims to emphasize and build upon the existing connections between compactifications, configurations, cohomology, and adjacent subjects. Recurring themes are likely to include algebraic groups, blow-ups, configuration spaces, hyperplane arrangements, Lie theory, and wonderful compactifications. The conference will be held from October 22nd at 1pm to October 24th at 12pm Event organizers: Alex Suciu […]
Third Graduate Student Conference: Geometry and Topology meet Data Analysis and Machine Learning
Join us for the third installment of GTDAML. The goal of the conference is to bring together graduate students to share their work, interests, and presence in the flourishing research landscape connecting applications of Geometry and Topology to Data Analysis and Machine Learning. We aim to enhance discussion and collaboration via poster sessions, short presentations, […]

Applied and Interdisciplinary Mathematics(AIM) Seminar This talk is jointly hosted with faculty from the Center for Theoretical Biological Physics and the Department of Bioengineering. Talk Title: Propagating waves of immune-virus coevolution Speaker: Thierry Mora (École Normale Supérieure in Paris) Date and time: November 28 at 3 pm Location: ISEC Room 432 (Northeastern University Interdisciplinary Science and Engineering Complex) Abstract: Fast-evolving viruses and immune systems play an evolutionary game of cat…
Applied and Interdisciplinary Mathematics (AIM) Seminar
Applied and Interdisciplinary Mathematics(AIM) Seminar Title: Wireless Video Streaming with Delayed Client-Feedback: A Constrained Decentralized Team View Speaker: Vijay Subramanian (University of Michigan) Date: Thursday, March 28, 2024 Time: 1:30-2:30 pm Location: 509/511 Lake Hall Abstract: We study the optimal control of multiple video streams over a wireless downlink from a base-transceiver-station (BTS)/access point to N end-devices (EDs). The BTS sends video packets to each ED under a joint transmission…
