When tested under a measured covariate shift, unweighted EnbPI coverage dropped significantly from 95% to 70.13%. Introducing weighted EnbPI, which uses density-ratio weighting, moderately recovered the coverage to 72.42%. Analysis using Formula 1 telemetry showed high unsupervised flag rates compared to in-distribution baselines, suggesting conformal adaptation is promising but incomplete for this domain shift problem.
Training AI models with risk aversion could limit severe consequences from misalignment by favoring safe cooperation over risky rebellion. Since training is currently limited to low-stakes scenarios, ensuring this aversion generalizes to extremely high stakes is crucial for safety. Researchers introduced RiskAverseOOD, a benchmark, and found that methods successfully induced substantial risk aversion in Qwen3-8B at astronomically high stakes. Specifically, the rate of choosing 'Cooperate' increased significantly from a baseline of 2% up to rates like 70% using SFT/tie training. While strong evidence shows generalization across models and scales, consistently guaranteeing this safety failsafe remains an open research problem.
CORA (Coherent Orthogonal Rotation Adaptation) is a novel Parameter-Efficient Fine-Tuning method that addresses the geometric preservation issue in SVD-based low-rank adaptations. It models adaptation by applying a shared orthogonal rotation ($Q_i$) independently to both the left and right singular bases of each row slice, alongside a diagonal spectrum shift. This approach utilizes per-slice orthogonal rotations and per-layer scaling on the rank-$r$ SVD truncation of the base weight $W_0$. CORA significantly reduces trainable parameters—using about $4\times$ fewer than LoRA at equivalent ranks. Evaluation shows CORA surpasses established methods like LoRA, DoRA, and PiSSA across commonsense reasoning and code generation tasks while requiring approximately $8\times$ fewer parameters.
Diffusion models do not exhibit benign overfitting, contrary to initial assumptions based on standard deep learning. Research establishes fundamental impossibility results showing that good generalization and overfitting cannot coexist unless sample size grows exponentially with data dimension. Consequently, the population loss in these models follows a classical U-shaped curve instead of exhibiting double descent. A key difference between regression and score matching—the latter lacks covariance alignment—makes overfitting irreparably harmful in diffusion modeling. Generalization in this domain is governed by mechanisms distinct from traditional regression, suggesting new theoretical development.
Analyzing contaminated multi-task empirical risk minimization in settings with task heterogeneity, the research identifies that common regularization or detection methods suffer from a suboptimal worst-case contamination error dependent on dimension $d$. The authors establish minimax lower bounds for this general setting, revealing a fundamental limitation for existing techniques. To overcome this, they propose a computationally efficient filtering-based robust multi-task gradient descent method. This new algorithm achieves high-probability upper bounds matching the optimal minimax rates, specifically removing the undesirable $\sqrt{d}$ contamination dependence. The proposed method demonstrates strong robustness and personalization capability across simulations and real-world data analysis.
Addresses reliability issues in selecting individuals based on predicted Conditional Average Treatment Effect (CATE) predictions. It proposes a method to control the False Discovery Rate (FDR) when selecting candidates whose CATE errors fall below a specified tolerance, even though these errors are unobservable. The approach constructs doubly robust proxy errors from pseudo-outcomes and addresses power loss due to heteroskedasticity. Denoised Conformal Alignment mitigates this by subtracting an estimated conditional variance component, combining conformal calibration with Benjamini--Hochberg selection. Experiments demonstrate that this method significantly improves statistical power while maintaining FDR control across complex settings.
Policy learning traditionally focuses on minimizing regret against the optimal policy using observational data. Recognizing limitations with insufficient data for low-regret guarantees, recent research has explored finding policies that statistically outperform baselines. This work establishes a mathematical framework covering three related problems: the beyond optimal policy problem, the improving policy problem, and the novel policy existence problem. The study demonstrates reductions showing each problem's difficulty relates to the next, with a strict gap proven between the optimal and improving policy settings. Furthermore, it shows gaps exist for the improving and existence problems under natural conditions, suggesting solvability even when an improving policy cannot be found.
High-dimensional data are assumed to lie near a low-dimensional manifold, a structure well-captured by mixture variational autoencoders (VAEs). These inherent geometric relationships allow for systematic missing data imputation. The proposed model leverages this structure by implementing a Sampling-Importance-Resampling (SIR) procedure to sample the missing data distribution $p(\bm{x}_{\mathrm{mis}} \mid \bm{x}_{\mathrm{obs}})$. This method can be enhanced with a joint diffusion model within the latent space for improved performance. Crucially, it imputes data while preserving underlying geometry and quantifies imputation uncertainty without needing to re-run the entire process.
Modern sequence models exhibit strong in-context learning (ICL) capability by leveraging prompt examples for new tasks. This work extends ICL theory beyond independent examples to address sequentially correlated data, a hallmark of real sequences. Using a solvable linear attention model, the authors tested predictions on actual transformer architectures. They discovered that when the query is independent of context, within-context correlations simulate a shorter effective context length for i.i.d. prompts. Furthermore, correlating the query with its context reduces test error, suggesting correlated prompts influence both effective sample size and optimal attention architecture matching.
RoBAS introduces a novel Bayes-assisted framework to create robust nonconformity scores for prediction sets. This approach combines Bayesian modeling strengths with guaranteed frequentist coverage, addressing issues caused by prior misalignment. RoBAS features two main components: one using a heavy-tailed working model and another employing an empirical Bayes shrinkage score. The method dynamically adapts; it utilizes strong prior information when reliable but defaults to the robust Distance-To-Average (DTA) score when the prior is weak or inaccurate. Evaluations on regression tasks demonstrate that RoBAS significantly reduces interval widths in settings where training data differs from test data, a scenario known as distribution shift.
Investigates identifying the treatment maximizing the expected natural direct potential outcome (NDPO), which isolates intervention effects excluding pathways via specified mediators. Establishes population-level identification of this NDPO within a causal bandit setting using observable interventional distributions. Develops a fixed-confidence best-arm identification (BAI) algorithm based on the Track-and-Stop framework and a cutting-set method for solving complex optimization problems. This novel algorithm achieves sample-efficient identification with proven $\delta$-correctness and asymptotic optimality guarantees. Validates the methodology using an analysis of a large-scale, real-world advertising dataset.
Conditional generative models are powerful tools, but their performance can vary when multiple generators are available. This paper proposes an optimal model averaging framework for these models, allowing combination even without tractable density estimates. It introduces StaticMA, which calculates fixed weights using sample-based maximum mean discrepancy between conditional distributions. Furthermore, it develops MoEMA, an input-adaptive method that uses a softmax neural network to parameterize covariate-dependent weights. Testing across tabular, image, and text data shows that MoEMA generally outperforms existing baseline methods.
