Why are these sophisticated (and costly) commercial threat detection products continuing to fail? In this talk, I'll describe our efforts to better understand, and even address, these failure points. First, I'll provide evidence that the extraordinarily high false alarm rates observed in Endpoint Detection & Response (EDR) products can be eliminated by examining the history of alert-triggering processes. Second, I'll explain how the metrics used to evaluate threat detection products often paint a deeply misleading picture of organizations' security readiness. I will conclude by discussing how our ongoing work seeks to resolve industry shortcomings by providing more principled foundations for threat detection and assessment. Bio: Adam Bates is an Associate Professor at the University of Illinois at Urbana-Champaign, where he studies a broad range of topics in computer security. He is best known for his work on data provenance, the practice of examining suspicious activities on computing systems based on their historical context. Fittingly, Adam also appreciates the historical context of computer security research, regularly forcing students in his courses to read James Anderson's 1972 Computer Security Technology and Planning Study… both volumes. Adam is the recipient of two distinguished paper awards (S&P'23, ESORICS'22) and was the runner-up for the ACM SIGSAC Dissertation Award. His research has been recognized and supported by an NSF SaTC FRONTIER, NSF CISE Research Initiation Initiative (CRII), and NSF CAREER Awards, as well as a gift from the VMWare University Research Fund.    TBD

We focus on the following setting: an algorithm is trained on sensitive data and the result is then exposed for public use -- how can we quantify the privacy risk of this exposure? Prior work typically focuses on providing privacy through privatizing specific algorithms. These techniques have two main drawbacks: (1) they require significant white-boxing per algorithm and (2) the privacy-utility tradeoffs may be hard to quantify.We first leverage the PAC privacy framework to mitigate the white-boxing requirements. In this talk, we show how we can privatize a wide range of database queries in a black-box manner. We discuss how to build a simple privatization layer, PAC-DB, that can provide provable privacy guarantees for general SQL queries. This allows us to expand the capabilities of private database analytics, enabling complex queries without the use of a trusted curator.We then focus on understanding the utility impacts of privatization. We focus on designing privacy-conscious algorithms. That is, rather than first constructing an algorithm then computing the noise required to privatize it --- a paradigm we refer to as post-hoc privatization --- we optimize the algorithm's hyperparameters given the privacy budget. We instantiate this via regularized linear regression. In particular, we derive the theoretically-optimal regularization weight to maximize utility under a provided privacy budget. We provide experimental results showing the benefits of privacy-conscious design over post-hoc privatization. TBD

Reliability, Availability, and Serviceability (RAS) are additional requirements for SoCs deployed at scale to ensure that computing is reliable and to minimize disruptions for long-running workloads such as AI training and scientific computing.However, improving RAS for HBM is challenging due to a combination of architectural limitations and practical considerations for a standardized solution. In this talk, I shall first provide a primer on DRAM RAS and define the problem statement for HBM RAS. I shall then present the research that was carried out in collaboration with the memory industry to develop an improved HBM resilience architecture. I shall present the data and analyses that drove this work, specific decisions made as we navigated a space of various design options, and the rationale for each decision. The outcome of this effort was a new HBM RAS architecture that was adopted in the third generation HBM standard (HBM3), has been commercialized by DRAM manufacturers, and is now used in GPUs and AI accelerators across industry. This RAS architecture is also included in the fourth generation HBM standard (HBM4) that was announced by JEDEC earlier this year.  Speaker BioSudhanva Gurumurthi is a Fellow at AMD, where he is responsible for research and advanced development in RAS. His work has impacted numerous AMD products, multiple industry standards, and external research in the field. Before joining industry, Sudhanva was an Associate Professor in the Computer Science Department at the University of Virginia. He currently serves as the Editor-in-Chief of IEEE Computer Architecture Letters and on the College of Science and Engineering advisory board at Texas State University.  Sudhanva is the recipient of an NSF CAREER Award, a Google Focused Research Award, and is named to the ISCA Hall of Fame. He received his PhD in Computer Science and Engineering from Penn State in 2005. TBD

The target structures are decomposed into rigid spatially varied quad tiles that are optimized to approximate the user-provided surface, forming a flat mechanical linkage. Our algorithm then uses a two-step method to find a physically realizable string path that controls only a subset of tiles to smoothly actuate the structure from flat to assembled configuration. We initially compute the minimal subset of tiles that are required to be controlled with the string considering the geometry of the structure and interaction among the tiles. We then find a valid string path through these tiles that minimizes friction, which will assemble the flat linkage into the target 3D structure upon tightening a single string. The resulting designs can be easily manufactured with computational fabrication techniques such as 3D printing, CNC milling, molding, etc. in flat configuration that, in addition to manufacturing, facilitates storage and transportation. We validate our approach by developing a series of physical prototypes and showcasing various application case studies, ranging from medical devices, space shelters, to architectural designs. TBD

On the other hand, it's presented as an unprecedented threat to humanity, with the danger of loss of jobs, loss of privacy, automated discrimination, even some kind of "robot rebellion". No wonder the public is confused. Which is it?We present a view that is different from both the self-interested promotion of the tech companies, and from the pessimism of the social critics. Believe it or not, the biggest value of AI will lie, not insimply improving the operations of today's industry and government, but in making it possible to have a more cooperative, less competitive world.Our view is:- Optimistic. Mitigating possible dangers of AI in today's society is important. But we don't want to let fear cause us to miss the potential for AI to tackle big problems people now think are intractable: war, poverty, climate, etc.- Radical. Many tech boosters imagine simply pouring AI into today's economy and electoral politics. We think these systems need to be redesigned from scratch for the AI era. We have two concrete proposals: Makerism (economics) and  Reasonocracy (governance).    - Original. Not conventionally Left or Right, though our ideas share some design goals with both sides. Not (yet) heard on mainstream or activist media. TBD

In all existing HSS schemes, parties participate in a correlated setup phase or a public-key infrastructure, then exchange shares of their inputs and perform local computations to obtain additive shares of the output.In the first part of the talk, we define multi-key homomorphic secret sharing (MKHSS), which replaces the setup in HSS with only a common reference string, and construct MKHSS for NC1 circuits from the decisional composite residuosity (DCR) assumption. This implies the first realization of succinct two-round secure computation for NC1 circuits without lattice-based assumptions.In the second part of the talk, we present optimizations to speed up the MKHSS construction by 45x. Crucial to this speedup is an insight that reduces the largest modulus from N^4 to N^2. As a bonus, we discover a structural simplification that is of independent interest to other HSS schemes.A practical application of MKHSS is a non-interactive conditional key exchange protocol, where two parties obtain the same key only if their inputs satisfy some predicate, which can be an arbitrary branching program. We give practical instantiations for two concrete predicates—geolocation proximity and fuzzy password matching—and achieve a total running time in a few seconds for realistic parameters.Joint works with Geoffroy Couteau (Université Paris Cité, CNRS, IRIF), Srini Devadas (MIT), Aditya Hedge (Johns Hopkins University), Abhishek Jain (Johns Hopkins University and NTT Research), and Sacha Servan-Schreiber (Tinfoil).

This thesis presents a comprehensive approach to understanding and mitigating hallucinations across several fundamental dimensions of knowledge in AI systems: parametric, contextual, and attribution knowledge.We identify that hallucinations arise from different failure modes requiring distinct solutions. First, models may fail to leverage parametric knowledge already encoded in their weights. We introduce DoLa (Decoding by Contrasting Layers), which amplifies factual knowledge by dynamically contrasting predictions across transformer layers, improving factuality without training or external knowledge. Second, in retrieval-augmented generation settings, models often fail to properly use provided context. We develop Lookback Lens, which analyzes attention patterns to detect and reduce hallucinations. Third, even when models generate correct content, users need verifiable evidence. We present SelfCite, a self-supervised alignment method that enables LLMs to provide accurate sentence-level citations through a reward design of context ablation. Together, these methods form a roadmap towards better AI systems, working towards systems that are not only capable but also reliable, transparent, and trustworthy. TBD

Often, algorithmic tasks can be greatly sped up for inputs that are promised to have certain structural properties, such as inputs that are assumed to be random, or to come from restricted classes of graphs. However, in practice, we rarely know if these promises hold, and verifying them can cost more than using a worst case algorithm. This talk surveys emerging lines of work that build trustworthy fast algorithms, by pairing speedups with weaker notions of testability. Our new algorithms, which either give an answer that is certified to be correct, or flag the input as one that does not satisfy the promised conditions, have complexities that are significantly faster than that of algorithms that do not rely on promises. This talk will discuss works that are joint with Arsen Vasilyan, Talya Eden, Cassandra Marcussen, and Madhu Sudan.

Generalization measures (GMs) are a central tool for providing performance guarantees and informing algorithmic design. Yet, most such bounds are known to be loose (or even vacuous) in practise. In a series of works [1, 2], we focus on GMs in the overparametrized supervised learning setting, where we show that this looseness is unavoidable due to fundamental lower bounds. Notably, these lower bounds hold on average over finite collections of distributions, and with numerically appreciable values.For GMs that are computed solely from the training sample but depend on neither the algorithm nor distribution, we show non-tightness across a large fraction of (algorithm, distribution) combinations.For GMs that can also depend on the algorithm, we show that there can be a trade-off between the algorithm’s ability to learn and the ability to verify the algorithm’s learning success with a GM.Next, we study algorithm-dependent GMs for algorithms that admit a natural notion of algorithmic implicit bias. There, non-tightness of GMs provably occurs whenever the underlying distribution class is rich enough, which is the case for example when learning VC-classes.Lastly, we show that a certain notion of algorithmic stability is sufficient for the existence of tight GMs.Joint work with Ido Nachum (University of Haifa), Jonathan Shafer (MIT), and Michael Gastpar (EPFL).[1]: ICLR 2024, see https://arxiv.org/abs/2309.13658[2]: Neurips 2025 (Spotlight), see https://arxiv.org/abs/2410.01969 TBD

One popular example is the usage of graph Laplacian eigenvectors for positional encoding in MPNNs and Graph Transformers. We leverage a well-studied paradigm of classifying graphs by their largest eigenvalue multiplicity to introduce an expressivity hierarchy for SGNNs. We then prove that many SGNNs are incomplete even on graphs with distinct eigenvalues. To mitigate this deficiency, we adapt rotation equivariant neural networks to the graph spectra setting to propose a method to provably improve SGNNs’ expressivity on simple spectrum graphs. TBD

Add to Calendar 2026-02-17 12:00:00 2026-02-17 13:00:00 America/New_York Visual Computing Seminar: Learning a distance measure from the information-estimation geometry of data Abstract:The perceptual distance between images is widely believed to be related to the distribution of natural images. But how can a probability distribution give rise to a distance measure—let alone one that aligns with human perception? What properties should such a distance satisfy, and how can it be learned from an image database in an unsupervised manner? In this talk, I will address these questions by presenting the Information–Estimation Metric (IEM), a novel form of distance function derived from a given probability density over a domain of signals. The IEM is rooted in a fundamental relationship between information theory and estimation theory, which links the log-probability of a signal with the errors of an optimal denoiser, applied to noisy observations of the signal. For Gaussian-distributed signals, the IEM coincides with the Mahalanobis distance. But for more complex distributions, it adapts, both locally and globally, to the geometry of the distribution. I will discuss and illustrate the theoretical properties of the IEM—including its global and local behavior. Finally, I will demonstrate that the IEM effectively predicts human perceptual judgments when trained (unsupervised) on natural images.Bio:Guy is a postdoctoral researcher working with Eero Simoncelli at the Flatiron Institute. His research focuses on developing computational models of human perception that are grounded in principles from information theory. He received his PhD in Computer Science from the Technion—Israel Institute of Technology, where he worked with Michael Elad and Tomer Michaeli on the design and theoretical analysis of image restoration and compression methods that rely on generative models.
