SUMMARY:Workshop / Seminar:Statistics Department Seminar Series: Xianyang Zhang\, Professor\, Department of Statistics\, Texas A&M University.
DESCRIPTION:Abstract: The rapid adoption of large language models (LLMs)\, such as GPT-4 and Claude 3.5\, underscores the need to distinguish LLM-generated text from human-written content to mitigate the spread of misinformation\, misuse in education\, and LLM training data contamination. One promising approach to address this issue is the watermark technique\, which embeds subtle statistical signals into LLM-generated text to enable reliable identification. In this work\, we enhance watermark detection using adaptive methods that assign higher weights to tokens with smaller next-token probabilities (NTPs)\, where NTPs quantify the likelihood of a token appearing based on its preceding context. We rigorously analyze the Type I and Type II error of the proposed method and demonstrate its superior detection power through numerical experiments. Due to the unavailability of true prompts and\, thus\, true NTPs\, we introduce a prompt estimation method that identifies the most likely prompt from an instruction set to estimate NTPs. Furthermore\, we develop a statistical framework for segmenting text into watermarked and non-watermarked substrings by framing it as a change point detection problem. Extensive experiments validate the proposed methods\, demonstrating their effectiveness in detection\, segmentation\, and robustness.\n\n\nhttps://zhangxiany-tamu.github.io/

SUMMARY:Exhibition:Unsettling Histories: Legacies of Slavery and Colonialism
DESCRIPTION:Organized as a response to the Museum’s recent acquisition of Titus Kaphar’s Flay (James Madison)\, this upcoming reinstallation of one of our most prominent gallery spaces forces us to grapple with our collection of European and American art\, 1650-1850.\n \nIn recent times\, growing public awareness of the continued reverberations of the legacy of slavery and colonization has challenged museums to examine the uncomfortable histories contained in our collections\, and challenged the public to probe the choices we make about those stories. Choices about which artists you see in our galleries\, choices about what relevant facts we share about the works\, and choices about what - out of an infinite number of options - we don’t say about them.\n \nPieces in this exhibition were made at a time when the world came to be shaped by the ideologies of colonial expansion and Western domination. And yet\, that history and the stories of those marginalized do not readily appear in the still lives and portraits on display here. By grappling with what is visible and what remains hidden\, we are forced to examine whose stories and histories are prioritized and why.  \n \nIn this online exhibition\, you can explore our efforts to deeply question the Museum’s collection and our own past complicity in favoring colonial voices. In the Museum gallery\, which will open in early 2021\, you’ll be able to experience the changes we’re making to the physical space to highlight a more honest version of European and American history. \n \nBy challenging our own practice\, and continuing to add to what we know and what we write about the works we display\, UMMA tells a more complex and more complete story of this nation - one that unsettles\, and fails to settle for\, simple narratives. \n \n“Invisible things are not necessarily ‘not there’.... Certain absences are so stressed\, so ornate\, so planned\, they call attention to themselves\; arrest us with intentionality and purpose\, like neighborhoods that are defined by the population held away from them.” \n \n— Toni Morrison\n\nLead support for Unsettling Histories: Legacies of Slavery and Colonialism is provided by the University of Michigan Office of the Provost\, the U-M Arts Initiative\, and the Susan and Richard Gutow Endowed Fund.\n
