BayesAgent: Bayesian Agentic Reasoning Under Uncertainty via Verbalized Probabilistic Graphical Modeling

AAAI 2026technical

Human cognition excels at transcending sensory input and forming latent representations that structure our understanding of the world. While Large Language Model (LLM) agents demonstrate emergent reasoning and decision-making abilities, they lack a principled framework for capturing latent structure

LERD: Latent Event-Relational Dynamics for Neurodegenerative Classification

ICML 2026poster

Alzheimer’s disease (AD) alters brain electrophysiology and disrupts multichannel EEG dynamics, making accurate and clinically useful EEG-based diagnosis increasingly important for screening and disease monitoring. However, many existing approaches rely on black-box classifiers and do not explicitly…

iLoRA: Bayesian Low-Rank Adaptation with Latent Interaction Graphs for Microbiome Diagnosis

ICML 2026poster

Reliable microbiome-based diagnosis is critical for precision medicine at scale in inflammatory diseases, yet current post-training pipelines in LLMs often overlook the interaction structure that governs microbial ecosystems. In inflammatory bowel disease (IBD), disease signals arise not only from s…

On Calibration of LLM-based Guard Models for Reliable Content Moderation

ICLR 2025poster

Large language models (LLMs) pose significant risks due to the potential for generating harmful content or users attempting to evade guardrails. Existing studies have developed LLM-based guard models designed to moderate the input and output of threat LLMs, ensuring adherence to safety policies by b…

Benchmarking Large Language Models on Communicative Medical Coaching: A Dataset and a Novel System

ACL 2024findings

Traditional applications of natural language processing (NLP) in healthcare have predominantly focused on patient-centered services, enhancing patient interactions and care delivery, such as through medical dialogue systems. However, the potential of NLP to benefit inexperienced doctors, particularl…

Composite Active Learning: Towards Multi-Domain Active Learning with Theoretical Guarantees

AAAI 2024technical

Active learning (AL) aims to improve model performance within a fixed labeling budget by choosing the most informative data points to label. Existing AL focuses on the single-domain setting, where all data come from the same domain (e.g., the same dataset). However, many real-world tasks often invol…

FedNP: Towards Non-IID Federated Learning via Federated Neural Propagation

AAAI 2023technical

Traditional federated learning (FL) algorithms, such as FedAvg, fail to handle non-i.i.d data because they learn a global model by simply averaging biased local models that are trained on non-i.i.d local data, therefore failing to model the global data distribution. In this paper, we present a nove…

Extrapolative Continuous-time Bayesian Neural Network for Fast Training-free Test-time Adaptation

NeurIPS 2022accept

Human intelligence has shown remarkably lower latency and higher precision than most AI systems when processing non-stationary streaming data in real-time. Numerous neuroscience studies suggest that such abilities may be driven by internal predictive modeling. In this paper, we explore the possibili…

STRODE: Stochastic Boundary Ordinary Differential Equation

ICML 2021spotlight

Perception of time from sequentially acquired sensory inputs is rooted in everyday behaviors of individual organisms. Yet, most algorithms for time-series modeling fail to learn dynamics of random event timings directly from visual or audio inputs, requiring timing annotations during training that a…

Deep Graph Random Process for Relational-Thinking-Based Speech Recognition

ICML 2020poster

Lying at the core of human intelligence, relational thinking is characterized by initially relying on innumerable unconscious percepts pertaining to relations between new sensory signals and prior knowledge, consequently becoming a recognizable concept or object through coupling and transformation o…

An investigation of augmenting speaker representations to improve speaker normalisation for DNN-based speech recognition

ICASSP 2015accepted

The conventional short-term interval features used by the Deep Neural Networks (DNNs) lack the ability to learn longer term information. This poses a challenge for training a speaker-independent (SI) DNN since the short-term features do not provide sufficient information for the DNN to estimate the…
