A Fiber Criterion for Representation Identifiability in Supervised Learning

A new theoretical framework formalizes when representation properties in supervised learning can be uniquely identified from input-output behavior alone. The research demonstrates that representation-level claims require additional assumptions beyond predictive performance, as auxiliary information can be added to representations while preserving predictor outputs, fundamentally challenging common assumptions about what supervised learning actually determines.

CIVeX: Causal Intervention Verification for Language Agents

Researchers introduce CIVeX, a causal intervention verifier that validates whether tool-calling language agents' proposed actions will actually produce intended effects in real-world execution. The system achieves zero false executions under adversarial conditions and outperforms LLM-based verification approaches by ensuring causal identifiability rather than just schema validity.

Does Your Neural Network Extrapolate? Feature Engineering as Identifiability Bias for OOD Generalization

Researchers demonstrate that neural networks fail at out-of-distribution (OOD) generalization not due to insufficient training data, but because the choice of feature representation fundamentally determines what extrapolation patterns a model can learn. The same architecture achieving identical in-distribution loss can differ by 520x out-of-distribution depending on how features are encoded, showing that correct feature engineering is necessary but not sufficient without appropriate model class constraints.

Computational Identifiability

Researchers propose 'computational identifiability,' a new framework that redefines how causal effects are identified in data science by shifting from theoretical, infinite-data assumptions to practical, finite computational search procedures. This approach enables identification under realistic conditions including small samples, ambiguous graphical criteria, and mixed observational-interventional data.

Beyond Additivity: Causal Discovery in Location-Scale Noise Models with Hidden Variables

Researchers develop a new causal discovery method for identifying cause-effect relationships in data with hidden variables and non-additive noise, proving identifiability under location-scale noise models and introducing the LSNM-UV algorithm that outperforms existing additive approaches on heteroscedastic data.

Intervention-Based Time Series Causal Discovery via Simulator-Generated Interventional Distributions

Researchers introduce SVAR-FM, a framework that uses physics-based simulators to discover causal relationships in time series data by treating simulation interventions as Pearl's do operator. The method recovers correct causal directions where observational methods fail due to confounding, with theoretical guarantees and empirical validation across multiple scientific domains.
