Simple Extensions of Single-Objective Acquisition Functions and Hedge Strategies for Multi-Objective Bayesian Optimization

A framework that extends standard single-objective acquisition functions directly to the multi-objective setting through a hypervolume-based transformation and extends hedge strategies for acquisition functions, which are typically used only in single-objective optimization, to the multi-objective regime is proposed.

Symmetry-quotient Flatness and Generalization

A theorem-level pipeline in symmetry-quotient settings is developed: quotient linear stability implies quotient flatness, quotient flatness implies input smoothness, and input smoothness yields generalization under local covering assumptions.

Simulating Eutopia: Revisiting Long-term Fairness with Outcomes, Performativity, and Dynamics

This paper revisit the nuances of long-term fairness achievable by an ADM-- specifically, through the lens of a loan approver inducing a population-level wealth dynamics, by developing Eutopia: a lending-process simulator enabled with a novel performative data generator to learn long-term fair strategies.

Anytime Training with Schedule-Free Spectral Optimization

SF-NorMuon, a schedule-free spectral optimizer that closes the performance gap with tuned AdamW baselines, makes horizon-free optimization more practical, taking a step towards truly open-ended, continual learning.

BGM-IV: AI-Powered Bayesian Generative Modeling for Instrumental Variable Regression with High-Dimensional Covariates

BGM-IV, a Bayesian generative modeling approach that performs nonlinear IV regression through posterior inference in a causally structured latent space, outperforms existing nonlinear IV methods overall, with significant gains in high-dimensional settings, while achieving near-nominal predictive coverage.

Relative Density Ratio Optimization for Stable and Statistically Consistent Model Alignment

The proposed alignment method is statistically consistent and yields significantly tighter convergence guarantees than DDRO, and is based on the relative density ratio between the preferred data distribution and a mixture of the preferred and non-preferred data distributions.

Contextual Distributionally Robust Optimization with Causal and Continuous Structure: An Interpretable and Tractable Approach

A soft regression forest decision rule is proposed that preserves the interpretability of classical decision trees while being fully parametric, differentiable, and Lipschitz-smooth, enabling intrinsic interpretation from both global and local perspectives.

Soft Geometric Inductive Bias for Object Centric Dynamics

Compared to both unstructured baselines and strictly equivariant models, the soft Clifford transformer achieves better long-horizon fidelity, particularly in regimes with broken symmetries, suggesting that geometric algebra offers an effective middle ground.

On the Interaction of Compressibility and Adversarial Robustness

As demands for resource efficiency and safety in modern neural networks intensify, substantial research effort has gone into model compression and adversarial robustness. Yet despite progress on each in isolation, a systematic understanding of how compressibility shapes robustness remains elusive. In this paper, we dev...

Help Me Help You: The Aggregate Value of Source and Target Data in Transfer Learning

This work identifies and characterize an interesting dichotomy in the rates achievable in the supervised setting: there is a weak transfer regime where optimal rates are determined by information in either the source or target dataset but not both, and a strong transfer regime where much faster target rates are achieva...

Understanding Generalization Requires Universal Induction

Solomonoff induction is relativized to an information vantage point, biasing toward short programs with access to all preexisting information, which reframes the inductive bias: instead of seeking some absolute notion of simplicity, it favor accessibility with respect to the authors' vantage point.
