From Tokenizer Bias to Backbone Capability: A Controlled Study of LLMs for Time Series Forecasting

This paper investigates the inherent forecasting capabilities of large language models (LLMs) by controlling for tokenizer bias through large-scale pre-training, revealing that while LLM backbones show some promise, they still struggle to consistently outperform models specifically trained on large-scale time series data.

The Malicious Technical Ecosystem: Exposing Limitations in Technical Governance of AI-Generated Non-Consensual Intimate Images of Adults

This paper adopts a survivor-centered approach to expose how a "malicious technical ecosystem" of accessible tools enables the creation of AI-generated non-consensual intimate images, while demonstrating that current governance frameworks, such as the NIST AI 100-4 report, fail to effectively regulate this landscape due to flawed underlying assumptions.

Entropic Mirror Descent for Linear Systems: Polyak's Stepsize and Implicit Bias

This paper introduces a variant of Polyak's stepsizes for entropic mirror descent to solve linear systems without restrictive domain assumptions, establishing sublinear and linear convergence rates, strengthening 1\ell_1-norm implicit bias bounds, and generalizing results to arbitrary convex LL-smooth functions while proposing an exponentiation-free alternative method.
