PhaseCoder: Microphone Geometry-Agnostic Spatial Audio Understanding for Multimodal LLMs

ICML 2026poster

Current multimodal LLMs process audio as a mono stream, ignoring the rich spatial information essential for embodied AI. Existing spatial audio models, conversely, are constrained to fixed microphone geometries, preventing deployment across diverse devices. We present PhaseCoder, a transformer-only …

Ask the experts: sourcing a high-quality nutrition counseling dataset through Human-AI collaboration

EMNLP 2024finding

Large Language Models (LLMs) are being employed by end-users for various tasks, including sensitive ones such as health counseling, disregarding potential safety concerns. It is thus necessary to understand how adequately LLMs perform in such domains. We conduct a case study on ChatGPT in nutrition…

MABe22: A Multi-Species Multi-Task Benchmark for Learned Representations of Behavior

ICML 2023poster

We introduce MABe22, a large-scale, multi-agent video and trajectory benchmark to assess the quality of learned behavior representations. This dataset is collected from a variety of biology experiments, and includes triplets of interacting mice (4.7 million frames video+pose tracking data, 10 millio…

SPAE: Semantic Pyramid AutoEncoder for Multimodal Generation with Frozen LLMs

NeurIPS 2023spotlight

In this work, we introduce Semantic Pyramid AutoEncoder (SPAE) for enabling frozen LLMs to perform both understanding and generation tasks involving non-linguistic modalities such as images or videos. SPAE converts between raw pixels and interpretable lexical tokens (or words) extracted from the LLM…

Anno-MI: A Dataset of Expert-Annotated Counselling Dialogues

ICASSP 2022accepted

Research on natural language processing for counselling dialogue analysis has seen substantial development in recent years, but access to this area remains extremely limited due to the lack of publicly available expert-annotated therapy conversations. In this work, we introduce AnnoMI, the first pub…

Practice Makes a Solver Perfect: Data Augmentation for Math Word Problem Solvers

NAACL 2022long

Existing Math Word Problem (MWP) solvers have achieved high accuracy on benchmark datasets. However, prior works have shown that such solvers do not generalize well and rely on superficial cues to achieve high performance. In this paper, we first conduct experiments to showcase that this behaviour i…

Adversarial Examples for Evaluating Math Word Problem Solvers

EMNLP 2021finding

Standard accuracy metrics have shown that Math Word Problem (MWP) solvers have achieved high performance on benchmark datasets. However, the extent to which existing MWP solvers truly understand language and its relation with numbers is still unclear. In this paper, we generate adversarial attacks t…
