SUMMARY:Behavioral\, Econometrics and Theory Seminar Series Presents: Kevin Chen
DESCRIPTION:Economics Behavioral\, Econometrics\, & Theory Seminar\nDate: Thursday\, October 23\, 2025\nTime: 1:40-3:00 p.m.\nLocation: Engineering 2\, Rm 499\n\n \n\nSpeaker: Kevin Chen \nTitle:  Assistant Professor of Economics \nAffiliation: Stanford University\nHost: Michael Leung\n \nSeminar title: Compound Selection Decisions: An Almost SURE Approach \n \nABSTRACT:  This paper proposes methods for producing compound selection decisions in a Gaussian sequence model. Given unknown\, fixed parameters µ_{1:n} and known σ_{1:n} with observations Yᵢ ∼ 𝒩(μᵢ\, σᵢ²)\, the aim is to select a subset of units S to maximize utility Σ_{i∈S}(μᵢ − Kᵢ) for known costs Kᵢ. Inspired by Stein’s unbiased risk estimate (SURE)\, we introduce an almost unbiased estimator\, ASSURE\, for the expected utility of a proposed decision rule. ASSURE allows a user to choose a welfare-maximizing rule from a pre-specified class by optimizing the estimated welfare\, thereby producing selection decisions that borrow strength across noisy estimates. We show that ASSURE yields decision rules that are asymptotically no worse than the optimal but infeasible rule in the pre-specified class. We apply ASSURE to p-value decision procedures in A/B testing\, selecting Census tracts for economic opportunity\, and identifying discriminating firms.

SUMMARY:Robots that Know What They Do Not Know: Assured AI-enabled Autonomy in Unknown Environments
DESCRIPTION:Speaker: Yiannis Kantaros\, Assistant Professor\, Electrical and Systems Engineering at WashU in St. Louis. \nTitle: Robots that Know What They Do Not Know: Assured AI-enabled Autonomy in Unknown Environments. \nTime: Thursday\, Oct 23rd\, 2025\, 2:00-3:00 pm. \nLocation: E2-553 or Zoom. \nAbstract: Designing robots that navigate unfamiliar environments to execute natural language (NL) commands is a cornerstone of advanced embodied intelligence. While recent AI-enabled architectures have made impressive empirical progress\, they often lack introspection\, leading to systems that act with unwarranted confidence\, unaware of their own limitations or whether they have successfully completed their tasks. As a result\, these systems offer limited performance and safety guarantees\, restricting their deployment in safety-critical settings.\nIn this talk\, I will present an introspective\, neuro-symbolic autonomy architecture that enables robots to complete NL tasks in unknown environments with assurance guarantees by explicitly quantifying their own uncertainty using uncertainty quantification (UQ) tools. The neural component employs large language models (LLMs) to translate NL commands into temporal logic specifications\, while leveraging conformal prediction\, a UQ tool\, to calibrate and quantify prediction uncertainty arising from LLM imperfections and potential NL ambiguity. When uncertainty exceeds user-defined thresholds\, uncertainty-aware feedback is solicited from auxiliary LLMs—or\, if necessary\, from human operators. We provide theoretical guarantees\, supported by empirical case studies\, that the proposed uncertainty-aware translation framework\, called ConformalNL2LTL\, achieves user-specified translation success rates under certain distributional settings. The symbolic component generates plans for mobile robots with AI-enabled perception systems to satisfy temporal logic tasks while explicitly reasoning over perceptual and environmental uncertainty. This allows robots to decide when to proceed confidently and when to actively gather additional sensor data\, ensuring task completion with the desired probability. Notably\, the developed planners are agnostic to specific sensor models or noise characteristics. The talk will conclude with case studies and demonstrations\, followed by a discussion of limitations and open problems. \nSpeaker Bio: Yiannis Kantaros is an Assistant Professor in the Department of Electrical and Systems Engineering\, Washington University in St. Louis (WashU)\, St. Louis\, MO\, USA. He earned a Diploma in Electrical and Computer Engineering in 2012 from the University of Patras\, Greece\, and M.Sc. and Ph.D. degrees in Mechanical Engineering from Duke University\, Durham\, NC\, in 2017 and 2018\, respectively.

SUMMARY:Mary Roach - Replaceable You
DESCRIPTION:Bookshop Santa Cruz welcomes #1 New York Times bestselling author Mary Roach for a discussion about Replaceable You: Adventures in Human Anatomy. In this irrepressible new work\, Mary Roach explores the remarkable advances and difficult questions prompted by the human body’s failings. When and how does a person decide they’d be better off with a prosthetic than their existing limb? Can a donated heart be made to beat forever? Can an intestine provide a workable substitute for a vagina? \n \nThe body is the most complex machine in the world\, and the only one for which you cannot get a replacement part from the manufacturer. For centuries\, medicine has reached for what’s available–sculpting noses from brass\, borrowing skin from frogs and hearts from pigs\, crafting eye parts from jet canopies and breasts from petroleum by-products. Today we’re attempting to grow body parts from scratch using stem cells and 3D printers. How are we doing? Are we there yet? Irrepressible and accessible\, Replaceable You immerses readers in the wondrous\, improbable\, and surreal quest to build a new you. This event is cosponsored by The Humanities Institute at UC Santa Cruz. \nMary Roach is the author of seven best-selling works of nonfiction\, including Grunt\, Stiff\, and\, most recently\, Fuzz. Her writing has appeared in National Geographic and the New York Times Magazine\, among other publications. She lives in California.

SUMMARY:ECE 290 Seminar: Performance Bounds and Bottlenecks for Neuromorphic ML Accelerators
DESCRIPTION:Presenter: Jason Yik\, PhD Candidate\, Harvard SEAS \nDescription: Recent research on neuromorphic accelerators has investigated their efficiency and performance benefits for machine learning (ML) inference at the edge. This talk will focus on the performance implications of the fully-on-chip\, manycore-distributed memory architecture used by current neuromorphic accelerators. In conventional architectures\, the roofline model is a well-known performance model for denoting performance bounds and bottlenecks. For neuromorphics\, we show that bounds create a different shape\, a floorline\, and we demonstrate how to optimize ML deployment using the floorline as a performance guide. \nBio: Jason Yik is a PhD candidate at Harvard SEAS\, with a research focus in neuromorphic computing architectures. His prior work includes designing benchmark frameworks and tools for neuromorphic research\, and modeling and optimizing neuromorphic system performance. Currently\, he is an intern with the ASIC architecture team at Cerebras Systems. \nHosted by: Professor Soumya Bose\, ECE Department \nZoom Link: https://ucsc.zoom.us/j/97975378707?pwd=ljcgaCfhMmhZ88Vt5dqQUBVQRjehOx.1 \nRoom: E2-192

SUMMARY:Statistics Seminar: Sampling Depth Trade-Off in Function Estimation Under a Two-Level Design
DESCRIPTION:Presenter: Akira Horiguchi\, Visiting Assistant Professor\, University of California\, Davis \nDescription: Many modern statistical applications involve a two-level sampling scheme that first samples subjects from a population and then samples observations on each subject. These schemes often are designed to learn both the population-level functional structures shared by the subjects and the functional characteristics specific to individual subjects. Common wisdom suggests that learning population-level structures benefits from sampling more subjects whereas learning subject-specific structures benefits from deeper sampling within each subject. Oftentimes these two objectives compete for limited sampling resources\, which raises the question of how to optimally sample at the two levels. We quantify such sampling-depth trade-offs by establishing the L_2 minimax risk rates for learning the population-level and subject-specific structures under a hierarchical Gaussian process model framework where we consider a Bayesian and a frequentist perspective on the unknown population-level structure. These rates provide general lessons for designing two-level sampling schemes given a fixed sampling budget. Interestingly\, they show that subject-specific learning occasionally benefits more by sampling more subjects than by deeper within-subject sampling. We show that the corresponding minimax rates can be readily achieved in practice through simple adaptive estimators without assuming prior knowledge on the underlying variability at the two sampling levels. We validate our theory and illustrate the sampling trade-off in practice through both simulation experiments and two real datasets. While we carry out all the theoretical analysis in the context of Gaussian process models for analytical tractability\, the results provide insights on effective two-level sampling designs more broadly. \nBio: Akira Horiguchi is a Visiting Assistant Professor in the Department of Statistics at the University of California\, Davis. He was a Postdoctoral Associate in the Department of Statistical Science at Duke University\, advised by Professors Li Ma and Cliburn Chan. He completed his Ph.D. in Statistics at The Ohio State University\, advised by Professors Matthew T. Pratola and Thomas J. Santner. His research interests include improving nonparametric inference for flow cytometry data\, developing sensitivity analysis tools for regression trees\, and developing tree-based methods for tensor regression. \nHosted by: Professor Paul Parker

SUMMARY:AM Seminar: Why do we care about inertial waves on the Sun?
DESCRIPTION:Presenter: Ms. Catherine Blume\, University of Colorado-Boulder \nDescription: Recent observations of Rossby waves and other inertial oscillations in the Sun’s convection zone have kindled the hope that such waves might be used as a seismic probe of the Sun’s interior. Here\, we present a 3D numerical simulation in spherical geometry that models the Sun’s convection zone and upper radiative interior. This model features a wide variety of inertial oscillations\, including both sectoral and tesseral Rossby waves\, retrograde mixed inertial modes\, prograde thermal Rossby waves\, and the recently observed high-frequency retrograde (HFR) vorticity modes. In this talk\, we’ll explore these different waves\, their physical impact\, and their potential helioseismic utility. \nBio: Catherine Blume is an astrophysics PhD student at the University of Colorado Boulder\, where she works with Brad Hindman studying solar inertial waves. \nHosted by: Professor Julie Simons

SUMMARY:Julian Brave NoiseCat - We Survived the Night
DESCRIPTION:Bookshop Santa Cruz welcomes Julian Brave NoiseCat who will share his stunning debut We Survived the Night. Drawing from five years of on-the-ground reporting\, We Survived the Night paints a profound and unforgettable portrait of contemporary Indigenous life\, alongside an intimate and deeply powerful reckoning between a father and a son. Soulful\, formally daring\, indelible work from an important new voice. \nThis event is cosponsored by the American Indian Resource Center and The Humanities Institute at UC Santa Cruz. It will take place at the London Nelson Community Center. \n \n“Written in gorgeous\, sparse prose\, We Survived the Night reads like a novel. Told with a blistering honesty\, the truth and grit create a beautifully woven coyote story we haven’t heard before. This is a love letter to Oakland\, to the Canim Lake Band Tsq’secen of the Secwepemc Nation\, to a father from his son\, to the act of being a Native person in the twenty first century finding ways to love even through all that wounds have opened and wrought. With this\, Julian Brave NoiseCat has written a book I’ve been waiting my whole life to read.” —Tommy Orange \nA stunning narrative from one of the most powerful young writers at work today—We Survived the Night (Knopf) interweaves oral history with hard-hitting journalism and a deeply personal father-son journey into a searing portrait of Indigenous survival\, love\, and resurgence. \nJulian Brave NoiseCat’s childhood was rich with culture and contradictions. When his Secwépemc and St’at’imc father\, an artist haunted by a turbulent past\, abandoned the family\, he and his non-Native mother were embraced by the urban Native community in Oakland\, California\, as well as by family on the Canim Lake Indian Reserve in British Columbia. In his father’s absence\, NoiseCat immersed himself in Native history and culture to understand the man he seldom saw—his past\, his story\, where he came from—and\, by extension\, himself. \nYears later\, NoiseCat sets out across the continent to correct the erasure\, invisibility\, and misconceptions surrounding the First Peoples of this land\, as he develops his voice as a storyteller and artist in his own right. \nJulian Brave NoiseCat is a writer\, Oscar-nominated filmmaker\, champion powwow dancer\, and student of Salish art and history. His writing has appeared in dozens of publications\, including The New York Times\, The Washington Post\, and The New Yorker. NoiseCat has been recognized with numerous awards including the 2022 American Mosaic Journalism Prize and many National Native Media Awards. He was a finalist for the Livingston Award and multiple Canadian National Magazine Awards\, and was named to the TIME100 Next list in 2021. His first documentary\, Sugarcane\, was nominated for an Academy Award for Best Documentary. Directed alongside Emily Kassie\, Sugarcane premiered at the 2024 Sundance Film Festival\, where NoiseCat and Kassie won the Directing Award in U.S. Documentary. NoiseCat is a proud member of the Canim Lake Band Tsq̓éscen̓ and descendant of the Líl̓wat Nation of Mount Currie. We Survived the Night is his first book.

SUMMARY:Alatawi\, A. (ECE) - Learning-Based Channel Estimation for Next-Generation Wireless Communications
DESCRIPTION:Accurate Channel State Information (CSI) is critical for coherent detection\, equalization\, and adaptive resource allocation in modern wireless systems. Traditional estimators rely on stationary statistical models\, and many learning-based methods assume training and deployment conditions are matched. In practice\, these assumptions break down under user mobility and environmental dynamics\, leading to degraded performance. This proposal explores machine-learning approaches for channel estimation that address two complementary challenges. \nFirst\, we develop an adaptive deep neural network (ADNN) for single-input single-output links over slowly time-varying channels. The method converts readily available physical-layer feedback—cyclic redundancy check (CRC) and automatic repeat request (ARQ)—into reliable self-supervision. Specifically\, packets decoded without errors are re-estimated using least squares (LS) across all symbols to generate high-quality labels\, and the DNN weights are periodically updated online. This design eliminates the need for ground-truth labels at deployment and enables continual learning. Simulations show that the ADNN tracks distributional shifts and recovers near–linear minimum mean-square error (LMMSE) performance in both mean-square error (MSE) and symbol error rate (SER)\, whereas a fixed offline-trained DNN degrades as channel statistics change. \nSecond\, we propose a sequence-to-sequence LSTM estimator for orthogonal frequency-division multiplexing (OFDM). The model exploits both temporal and frequency correlation by taking LS pilot estimates from several previous OFDM blocks as input and reconstructing the full channel frequency response of the current block. Trained on realistic time-selective channels such as WINNER II\, the LSTM outperforms LS interpolation and recent super-resolution–based methods across a wide range of SNRs\, pilot densities\, and temporal window sizes. \nFinally\, the proposal outlines future research on semantic-aware channel estimation using CSI timeliness\, and enhanced sequence models with DNN-refined pilots\, whole-block inputs\, and efficient GRU architectures. \nEvent Host: Abdulaziz Alatawi\, Ph.D. Student\, Electrical & Computer Engineering \nAdvisor: Hamid Sadjadpour & Zouheir Rezki \nZoom- https://ucsc.zoom.us/j/94895993579?pwd=Bs1ppmjqFvNknefRAHoVGXPSXxdZ6i.1 \nPasscode- 884927

SUMMARY:Macroeconomics & International Finance Seminar Series Presents: Zhiguo He
DESCRIPTION:Macroeconomics and International Finance Seminar\nDate: Tuesday\, October 28\, 2025\nTime: 1:40-3:00 p.m.\nLocation: E2-499\n\n \n\nSpeaker: Zhiguo He\nTitle: James Irvin Miller Professor of Finance\nAffiliation: Stanford University \nHost: Michael Leung \n \nSeminar title: Household Migration and Collateral Constraint: Cash-based Housing Resettlement in China\n \nABSTRACT:   Collateral constraints reduce household migration to expensive locations by restricting financing for home purchases. This endogenous location choice can amplify the impact of relaxing borrowing constraints. Using China’s cash-based shantytown renovation program (2015-2018) as a natural experiment\, we provide evidence that cash resettlement– by converting illiquid shanty houses into cash– facilitated household location upgrading and raised house prices in more expensive locations. A dynamic spatial model with collateral constraints confirms that endogenous location upgrading amplified the effect of cash transfer\, raising lifetime housing expenditures by nearly 50%\, and house price growth in low-tier cities by 9% in 2016-2020.

SUMMARY:Creative Interventions: "Asymptote" with Nora Khan
DESCRIPTION:Nora Khan explores our personal relationships with computational systems through moments spanning from childhood gaming experiences to contemporary AI. The central metaphor of the “asymptote”—a curve endlessly approaching but never reaching a line—describes both humanity’s pursuit of technological mastery\, and the incomputable aspects of experience that resist capture by algorithms and surveillance. Through encounters with drones\, machine learning systems\, and glitched game worlds\, this talk argues for maintaining space for the mystical\, ineffable\, and offscreen in an era of relentless quantification and prediction. The talk ultimately calls for preserving doubt\, acknowledging what cannot be computed\, and remembering the personal “why” that precedes professional identity in navigating our algorithmic present. \nThis event is presented as part of the Creative Interventions (CI) Series and is co-sponsored by the Arts Division’s Creative Technologies program and Porter College at UC Santa Cruz.\n—\nADMISSION\n– Free and open to UCSC affiliates.\n– This is an online event.\n– Registration is required here.\n—\nFULL SCHEDULE OF EVENTS\n– Event dates to be announced throughout the 2025-26 academic year.\n– Learn more about the Creative Intervention Series here.\n—\nABOUT THE SERIES\nCreative Interventions addresses the interconnected work of artists\, designers\, activists\, and knowledge workers—and the intrinsic and transformative capacity of that work to cultivate a just society.

SUMMARY:Queer Emergent: Scandalous Stories from Twilight of AIDS in Peru: Book Celebration and Conversation with Professor Justin Perez
DESCRIPTION:Join us as Huerta Center Faculty Awardee Professor Justin Perez (Latin America and Latino Studies Department) presents his new book\, Queer Emergent: Scandalous Stories from Twilight of AIDS in Peru. In Queer Emergent\, Justin Perez explores how advances in HIV prevention work alongside broader economic and political shifts in global health to shape queer subjectivities. Drawing on ethnographic research among gay and transgender communities in urban Amazonian Peru\, Perez describes how queer social worlds emerge through scandalous storytelling—a practice of exaggerating and embellishing stories about everyday life that transgresses social norms and hierarchies. Perez shows that through such storytelling\, gay and transgender communities contested the assumptions of global HIV prevention’s shift from the provision of costly antiretrovirals to the mitigation of social conditions like discrimination and stigma. He argues that the global ambition to “End AIDS” by 2030 is not just a technical project oriented at ending the epidemic\, but also a project of sexual subjectification and ongoing social transformation. By taking seriously the scandalous stories that gay and transgender Peruvians circulated as they responded to new forms of HIV prevention\, Perez reveals how they imagine possibilities of what could be as the effort to end AIDS continues to play out in the present. \nThere will be a short reception following the discussion. We look forward to seeing you there!

SUMMARY:BME 280B Seminar: Preconfigured neuronal firing sequences in human brain organoids
DESCRIPTION:Presenter: Tjitse (TJ) van der Molen\, Ph.D. (Postdoc\, Sharf Lab\, UC Santa Cruz and PhD Kosik Lab\, UC Santa Barbara) \nDescription: Neuronal firing sequences are thought to be the building blocks of information and broadcasting within the brain. Yet\, it remains unclear when these sequences emerge during neurodevelopment. Here we demonstrate that structured firing sequences appear in spontaneous activity of human and murine brain organoids\, both unguided and forebrain identity directed\, as well as ex vivo neonatal murine cortical slices. We observed temporally rigid and flexible firing patterns in human and murine brain organoids and early postnatal murine somatosensory cortex\, but not in dissociated primary cortical cultures. These results suggest that temporal sequences do not arise in an experience-dependent manner\, but are rather constrained by a preconfigured architecture established during neurodevelopment. By demonstrating the developmental recapitulation of neural firing patterns\, these findings highlight the potential of brain organoids as a model for neuronal circuit assembly. \nBio: Tjitse van der Molen studies spontaneous and evoked neural circuit activity in human and mouse stem cell derived brain organoids using dense multi electrode arrays. His main goal is to gain a better understanding of how healthy neural circuits process information and how possible malfunctions in neural circuit activity may result in disease\, in order to develop appropriate treatments. Tjitse recently completed his PhD in the Kosik lab at UC Santa Barbara and is now continuing his research as a postdoc in the Sharf lab at UC Santa Cruz. \nIn this talk\, Tjitse will present his latest manuscript that is currently in press with Nature Neuroscience\, focused on spontaneously occurring repeated sequential firing patterns that are present in the intrinsic activity of both brain organoids and neonatal mouse brain slices but not in 2D primary cultures. Similar sequential firing patterns have recently been shown to be important for information encoding and learning in the human cortex. The presence of these sequential firing patterns in the spontaneous activity of brain organoids that have never received external stimuli supports the notion that they develop in an experience-independent manner. \nHosted by: Professor Josh Stuart\, BME Department \nZoom Link: https://ucsc.zoom.us/j/99970819390?pwd=8sl5pd5TTBA5f6nqyCzo5mFpaqcEJG.1 \nFull Schedule: https://docs.google.com/document/d/1xD09vITwd_Pj9Ge6hHEuBFa5zBUYu2O-bjpSibt7VHE/edit?tab=t.0 \nRoom: PSB-240

SUMMARY:Applied Microeconomics and Trade Seminar Series presents: Shanjun Li
DESCRIPTION:Applied Microeconomics and Trade Seminar\nDate: Thursday\, October 30th\, 2025\nTime: 1:40-3:00 p.m.\nLocation: E2-499\n\n \n\nSpeaker: Shanjun Li\nPersonal Webpage \nTitle: Steven and Roberta Denning Professor of Global Sustainability \nAffiliation: Stanford University \nHost: Peter Christensen \n \nSeminar title: Range Anxiety\n \nABSTRACT:   Range anxiety\, the fear of depleting battery before reaching a charging station\, is often cited as a major barrier to electric vehicle (EV) adoption\, yet there has been limited formal economic analysis to quantify its importance and understand the policy implications. We develop a continuous-time dynamic model of EV usage and charging decisions to quantify range anxiety as the utility loss from feasible yet unrealized trips due to perceived range constraints. Using high-frequency data of 188\,000 EV trips and 30\,000 charging events among 8\,000 EVs in Shanghai\, we recover model parameters governing consumer driving and charging decisions. The estimates imply that\, across EV models with varying driving ranges\, average range anxiety was about $1\,900 in 2021 but declined to $1\,200 in 2024\, driven by improvements in charging infrastructure and\, especially\, in creases in driving range. Policy simulations underscore the importance of coordinating investments in battery capacity and charging infrastructure to address range anxiety: relative to socially optimal levels\, Shanghai’s EV market has under-invested in driving range while over-investing in charging infrastructure.
