The paper introduces CauKer, a novel algorithm that combines Gaussian Process kernel composition with Structural Causal Models to generate diverse, causally coherent synthetic time series, enabling sample-efficient pre-training of classification foundation models that exhibit clear scaling laws across varying dataset sizes and model capacities.
GraphProp is a two-phase framework for training graph foundation models that first learns structural generalization by predicting graph invariants and then leverages these representations as positional encodings to enhance cross-domain performance in graph-level tasks, particularly outperforming existing methods in scenarios with limited data or missing node attributes.
This paper demonstrates that gating mechanisms in recurrent neural networks act as data-driven preconditioners that couple state-space time-scales with parameter-space dynamics, inducing lag-dependent and anisotropic effective learning rates that complement optimizer-driven adaptivity to enhance trainability.

This paper proposes a unified training framework that combines entropy-driven curriculum learning, which sequences training from simple to complex trajectories based on Lempel-Ziv compression, with multi-task learning to simultaneously optimize location, distance, and direction predictions, thereby achieving state-of-the-art performance and significantly faster convergence in human mobility prediction.
This paper benchmarks Multivariate Imputation by Chained Equations (MICE) against deep generative models like Variational Autoencoders and Conditional Tabular GANs for synthetic ratemaking data, finding that MICE offers a simpler yet high-fidelity alternative that effectively preserves statistical distributions and supports robust Generalized Linear Model training.
This paper proposes the F²SA- method, which utilizes -th order finite differences to achieve a nearly optimal complexity for finding -stationary points in stochastic bilevel optimization with highly smooth objectives, thereby improving upon previous first-order bounds and matching the fundamental lower limit.
Through large-scale experiments with over 1.5 million LLM-generated behavioral sequences, this paper reveals a fundamental asymmetry in behavioral inference where agent motivations are nearly perfectly recoverable while belief systems remain largely opaque due to inherent information-theoretic limits and architectural constraints, particularly within a "neutral zone" of behavioral ambiguity.
This paper introduces a modular, multimodal framework that leverages generative AI to synthesize realistic residential building data from public images and information, thereby overcoming data accessibility and privacy barriers to advance energy modeling and machine learning research.

This paper introduces the first fully empirical PAC-Bayes bound for Markov chains by deriving a data-dependent estimate for the pseudo-spectral gap, thereby eliminating the need for unknown constants related to mixing properties that typically hinder practical generalization guarantees.
This paper demonstrates that linear probes used to detect harmful behaviors in language models are heavily reliant on explicit textual evidence, as their performance significantly degrades when such surface-level cues are filtered out or when models are trained to express behaviors without verbalization.
The paper introduces AEGIS, an edge-only augmentation framework that resamples existing training edges to enhance link prediction in edge-sparse bipartite knowledge graphs, demonstrating that authenticity-constrained resampling preserves data integrity while semantic KNN augmentation further boosts performance when node descriptions are available.
