Defeasible Visual Entailment: Benchmark, Evaluator, and Reward-Driven Optimization

AAAI 2025technical

We introduce a new task called Defeasible Visual Entailment (DVE), where the goal is to allow the modification of the entailment relationship between an image premise and a text hypothesis based on an additional update. While this concept is well-established in Natural Language Inference, it remains…

Towards Unbiased and Robust Spatio-Temporal Scene Graph Generation and Anticipation

CVPR 2025highlight

Spatio-Temporal Scene Graphs (STSGs) provide a concise and expressive representation of dynamic scenes by modeling objects and their evolving relationships over time. However, real-world visual relationships often exhibit a long-tailed distribution, causing existing methods for tasks like Video Scen…

Deep Dependency Networks and Advanced Inference Schemes for Multi-Label Classification

AISTATS 2024poster

We present a unified framework called deep dependency networks (DDNs) that combines dependency networks and deep learning architectures for multi-label classification, with a particular emphasis on image and video data. The primary advantage of dependency networks is their ease of training, in contr…

Grasping Trajectory Optimization with Point Clouds

IROS 2024poster

We introduce a new trajectory optimization method for robotic grasping based on a point-cloud representation of robots and task spaces. In our method, robots are represented by 3D points on their link surfaces. The task space of a robot is represented by a point cloud that can be obtained from depth…

Learning Distributionally Robust Tractable Probabilistic Models in Continuous Domains

UAI 2024poster

Tractable probabilistic models (TPMs) have attracted substantial research interest in recent years, particularly because of their ability to answer various reasoning queries in polynomial time. In this study, we focus on the distributionally robust learning of continuous TPMs and address the challen…

Learning to Solve the Constrained Most Probable Explanation Task in Probabilistic Graphical Models

AISTATS 2024poster

We propose a self-supervised learning approach for solving the following constrained optimization task in log-linear models or Markov networks. Let $f$ and $g$ be two log-linear models defined over the sets $X$ and $Y$ of random variables. Given an assignment $x$ to all variables in $X$ (evidence or…

Neural Network Approximators for Marginal MAP in Probabilistic Circuits

AAAI 2024technical

Probabilistic circuits (PCs) such as sum-product networks efficiently represent large multi-variate probability distributions. They are preferred in practice over other probabilistic representations, such as Bayesian and Markov networks, because PCs can solve marginal inference (MAR) tasks in time t…

A New Modeling Framework for Continuous, Sequential Domains

AISTATS 2023poster

Temporal models such as Dynamic Bayesian Networks (DBNs) and Hidden Markov Models (HMMs) have been widely used to model time-dependent sequential data. Typically, these approaches limit focus to discrete domains, employ first-order Markov and stationary assumptions, and limit representational power…

Conditionally Tractable Density Estimation using Neural Networks

AISTATS 2022poster

Tractable models such as cutset networks and sum-product networks (SPNs) have become increasingly popular because they have superior predictive performance. Among them, cutset networks, which model the mechanics of Pearl’s cutset conditioning algorithm, demonstrate great scalability and prediction a…
