DEEP TPC: TEMPORAL-PRIOR CONDITIONING FOR TIME SERIES FORECASTING

ICASSP 2026oral

LLM-for-time series (TS) methods typically treat time shallowly, injecting positional or prompt-based cues once at the input of a largely frozen decoder, which limits temporal reasoning as this information degrades through the layers. We introduce Temporal-Prior Conditioning (TPC), which elevates ti…

Mistake Attribution: Fine-Grained Mistake Understanding in Egocentric Videos

CVPR 2026

We introduce Mistake Attribution (MATT), a new task for fine-grained understanding of human mistakes in egocentric videos. While prior work detects whether a mistake occurs, MATT attributes the mistake to what part of the instruction is violated (semantic role), when in the video the deviation becom

When to Think and When to Look: Uncertainty-Guided Lookback

CVPR 2026

Test-time "thinking" (i.e., generating explicit intermediate reasoning chains) is known to boost performance in large language models and has recently shown strong gains for large vision-language models (LVLMs). However, despite these promising results, there is still no systematic analysis of how t

VITRO: Vocabulary Inversion for Time-series Representation Optimization

ICASSP 2025accepted

Although LLMs have demonstrated remarkable capabilities in processing and generating textual data, their pretrained vocabularies are ill-suited for capturing the nuanced temporal dynamics and patterns inherent in time series. The discrete, symbolic nature of natural language tokens, which these voca…
