Budgeted Active Experimentation for Treatment Effect Estimation from Observational and Randomized Data

ICML 2026poster

Estimating heterogeneous treatment effects is central to data-driven decision-making, yet industrial applications often face a fundamental tension between limited randomized controlled trial (RCT) budgets and abundant but biased observational data collected under historical targeting policies. Altho…

Feasible Fusion: Constrained Joint Estimation under Structural Non-Overlap

ICML 2026poster

Causal inference in modern large-scale systems faces growing challenges, including high-dimensional covariates, multi-valued treatments, massive observational (OBS) data, and limited randomized controlled trial (RCT) samples due to cost constraints. We formalize treatment-induced structural non-over…

MLUBench: A Benchmark for Lifelong Unlearning Evaluation in MLLMs

ICML 2026poster

Multimodal large language models (MLLMs) are trained on massive multimodal data, making data unlearning increasingly important as data owners may request the removal of specific content. In practice, these requests often arrive sequentially over time, giving rise to the challenging problem of *MLLM …

Partial Identification under High-Dimensional Potential Outcomes and Confounders via Optimal Transport

ICML 2026poster

Partial identification provides informative causal guarantees when point identification is impossible, but existing approaches based on optimal transport (OT) become computationally and statistically intractable in high-dimensional settings. This limitation is particularly severe when both potential…

Treatment Responder Classification with Abstention

ICML 2026spotlight

Treatment responder classification seeks to learn a rule to classify individuals who will benefit from the treatment. This paper studies a new scenario in treatment responder classification when abstention is allowed, i.e., practitioners can opt out of making uncertain classification on some individ…

Design-Based Bandits Under Network Interference: Trade-Off Between Regret and Statistical Inference

NeurIPS 2025poster

In multi-armed bandits with network interference (MABNI), the action taken by one node can influence the rewards of others, creating complex interdependence. While existing research on MABNI largely concentrates on minimizing regret, it often overlooks the crucial concern that an excessive emphasis…

Learning Person-Specific Animatable Face Models from In-the-Wild Images via a Shared Base Model

CVPR 2025poster

Training a generic 3D face reconstruction model in a self-supervised manner using large-scale, in-the-wild 2D face image datasets enhances robustness to varying lighting conditions and occlusions while allowing the model to capture animatable wrinkle details across diverse facial expressions. Howeve…

Unveiling Environmental Sensitivity of Individual Gains in Influence Maximization

NeurIPS 2025poster

Influence Maximization (IM) seeks a seed set to maximize information dissemination in a network. Elegant IM algorithms could naturally extend to cases where each node is equipped with a specific weight, reflecting individual gains to measure its importance. In prevailing literature, these gains are…

Improving Continual Few-shot Relation Extraction through Relational Knowledge Distillation and Prototype Augmentation

COLING 2024main

In this paper, we focus on the challenging yet practical problem of Continual Few-shot Relation Extraction (CFRE), which involves extracting relations in the continuous and iterative arrival of new data with only a few labeled examples. The main challenges in CFRE are overfitting due to few-shot lea…

Partial Identification with Proxy of Latent Confoundings via Sum-of-ratios Fractional Programming

UAI 2024poster

Causal effect estimation is a crucial theoretical tool in uncertainty analysis. The challenge of unobservable confoundings has raised concerns regarding quantitative causality computation. To address this issue, proxy control has become popular, employing auxiliary variables W as proxies for the con…

Tight Partial Identification of Causal Effects with Marginal Distribution of Unmeasured Confounders

ICML 2024spotlight

Partial identification (PI) presents a significant challenge in causal inference due to the incomplete measurement of confounders. Given that obtaining auxiliary variables of confounders is not always feasible and relies on untestable assumptions, researchers are encouraged to explore the internal i…

Unpaired Multi-domain Attribute Translation of 3D Facial Shapes with a Square and Symmetric Geometric Map

ICCV 2023poster

While impressive progress has recently been made in image-oriented facial attribute translation, shape-oriented 3D facial attribute translation remains an unsolved issue. This is primarily limited by the lack of 3D generative models and ineffective usage of 3D facial data. We propose a learning fram…
