$f$-Divergence Self-Play for Tabular Anomaly Detection via Large Language Models

ICML 2026poster

Anomaly detection in tabular data poses significant challenges due to heterogeneous feature types—mixing numerical, categorical, and textual attributes, which complicate learning meaningful representations of normality. Recent work has applied large language models (LLMs) to this problem by serializ…

Event-Grounding Graph: Unified Spatio-Temporal Scene Graph From Robotic Observations

RA-L 2026

A fundamental aspect for building intelligent autonomous robots that can assist humans in their daily lives is the construction of rich environmental representations. While advances in semantic scene representations have enriched robotic scene understanding, current approaches lack a connection betw

Identifying Causal Direction via Variational Bayesian Compression

ICML 2025spotlight

Telling apart the cause and effect between two random variables with purely observational data is a challenging problem that finds applications in various scientific disciplines. A key principle utilized in this task is the algorithmic Markov condition, which postulates that the joint distribution,…

REACT: Real-time Efficient Attribute Clustering and Transfer for Updatable 3D Scene Graph

IROS 2025

Modern-day autonomous robots need high-level map representations to perform sophisticated tasks. Recently, 3D scene graphs (3DSGs) have emerged as a promising alternative to traditional grid maps, blending efficient memory use and rich feature representation. However, most efforts to apply them have

Root Cause Explanation of Outliers under Noisy Mechanisms

AAAI 2024technical

Identifying root causes of anomalies in causal processes is vital across disciplines. Once identified, one can isolate the root causes and implement necessary measures to restore the normal operation. Causal processes are often modelled as graphs with entities being nodes and their paths/interconnec…

Memory-Augmented Theory of Mind Network

AAAI 2023technical

Social reasoning necessitates the capacity of theory of mind (ToM), the ability to contextualise and attribute mental states to others without having access to their internal cognitive structure. Recent machine learning approaches to ToM have demonstrated that we can train the observer to read the p…
