Architecture-Aware Learning Curve Extrapolation via Graph Ordinary Differential Equation

AAAI 2025technical

Learning curve extrapolation predicts neural network performance from early training epochs and has been applied to accelerate AutoML, facilitating hyperparameter tuning and neural architecture search. However, existing methods typically model the evolution of learning curves in isolation, neglectin…

SIMBA UQ: Similarity-Based Aggregation for Uncertainty Quantification in Large Language Models

EMNLP 2025

When does a large language model (LLM) know what it does not know? Uncertainty quantification (UQ) provides measures of uncertainty, such as an estimate of the confidence in an LLM’s generated output, and is therefore increasingly recognized as a crucial component of trusted AI systems. Black-box UQ

Concurrent Multi-Label Prediction in Event Streams

AAAI 2023technical

Streams of irregularly occurring events are commonly modeled as a marked temporal point process. Many real-world datasets such as e-commerce transactions and electronic health records often involve events where multiple event types co-occur, e.g. multiple items purchased or multiple diseases diagnos…

Pairwise Causality Guided Transformers for Event Sequences

NeurIPS 2023poster

Although pairwise causal relations have been extensively studied in observational longitudinal analyses across many disciplines, incorporating knowledge of causal pairs into deep learning models for temporal event sequences remains largely unexplored. In this paper, we propose a novel approach for e…

Probabilistic Attention-to-Influence Neural Models for Event Sequences

ICML 2023poster

Discovering knowledge about which types of events influence others, using datasets of event sequences without time stamps, has several practical applications. While neural sequence models are able to capture complex and potentially long-range historical dependencies, they often lack the interpretabi…

Score-Based Learning of Graphical Event Models with Background Knowledge Augmentation

AAAI 2023technical

Graphical event models (GEMs) are representations of temporal point process dynamics between different event types. Many real-world applications however involve limited event stream data, making it challenging to learn GEMs from data alone. In this paper, we introduce approaches that can work togeth…

Causal Inference for Event Pairs in Multivariate Point Processes

NeurIPS 2021poster

Causal inference and discovery from observational data has been extensively studied across multiple fields. However, most prior work has focused on independent and identically distributed (i.i.d.) data. In this paper, we propose a formalization for causal inference between pairs of event variables i…
