GAMMA: Gated Multi-hop Message Passing for Homophily-Agnostic Node Representation in GNNs

NeurIPS 2025poster

The success of Graph Neural Networks (GNNs) leverages the homophily principle, where connected nodes share similar features and labels. However, this assumption breaks down in heterophilic graphs, where same-class nodes are often distributed across distant neighborhoods rather than immediate connect…

Grammar-Forced Translation of Natural Language to Temporal Logic using LLMs

ICML 2025poster

Translating natural language (NL) into a formal language such as temporal logic (TL) is integral for human communication with robots and autonomous systems. State-of-the-art approaches decompose the task into a grounding of atomic propositions (APs) phase and a translation phase. However, existing m…

Attribution Quality Metrics with Magnitude Alignment

IJCAI 2024poster

Attribution algorithms play an instrumental role in human interpretation of AI models. The methods measure the importance of the input features to the model output decision, which can be displayed as an attribution map for image classifiers. Perturbation tests are the state-of-the-art approach to ev…

Integrated Decision Gradients: Compute Your Attributions Where the Model Makes Its Decision

AAAI 2024technical

Attribution algorithms are frequently employed to explain the decisions of neural network models. Integrated Gradients (IG) is an influential attribution method due to its strong axiomatic foundation. The algorithm is based on integrating the gradients along a path from a reference image to the inpu…

ExplainIt!: A Tool for Computing Robust Attributions of DNNs

IJCAI 2022poster

Responsible integration of deep neural networks into the design of trustworthy systems requires the ability to explain decisions made by these models. Explainability and transparency are critical for system analysis, certification, and human-machine teaming. We have recently demonstrated that neural…

Shaping Noise for Robust Attributions in Neural Stochastic Differential Equations

AAAI 2022technical

Neural SDEs with Brownian motion as noise lead to smoother attributions than traditional ResNets. Various attribution methods such as saliency maps, integrated gradients, DeepSHAP and DeepLIFT have been shown to be more robust for neural SDEs than for ResNets using the recently proposed sensitivity…

On Smoother Attributions using Neural Stochastic Differential Equations

IJCAI 2021poster

Several methods have recently been developed for computing attributions of a neural network's prediction over the input features. However, these existing approaches for computing attributions are noisy and not robust to small perturbations of the input. This paper uses the recently identified connec…
