TCD-Arena: Assessing Robustness of Time Series Causal Discovery Methods Against Assumption Violations

ICLR 2026poster

Causal Discovery (CD) is a powerful framework for scientific inquiry. Yet, its practical adoption is hindered by a reliance on strong, often unverifiable assumptions and a lack of robust performance assessment. To address these limitations and advance empirical CD evaluation, we present **TCD-Arena*…

CausalRivers - Scaling up benchmarking of causal discovery for real-world time-series

ICLR 2025spotlight

Causal discovery, or identifying causal relationships from observational data, is a notoriously challenging task, with numerous methods proposed to tackle it. Despite this, in-the-wild evaluation of these methods is still lacking, as works frequently rely on synthetic data evaluation and sparse real…

FastCAV: Efficient Computation of Concept Activation Vectors for Explaining Deep Neural Networks

ICML 2025poster

Concepts such as objects, patterns, and shapes are how humans understand the world. Building on this intuition, concept-based explainability methods aim to study representations learned by deep neural networks in relation to human-understandable concepts. Here, Concept Activation Vectors (CAVs) are…
