TAAT: Think and Act from Arbitrary Texts in Text2Motion

no code implementations23 Apr 2024 Runqi Wang, Caoyuan Ma, Guopeng Li, Zheng Wang

In this challenging dataset, we benchmark existing state-of-the-art methods and propose a novel two-stage framework to extract action labels from arbitrary texts by the Large Language Model (LLM) and then generate motions from action labels.

Unleashing Unlabeled Data: A Paradigm for Cross-View Geo-Localization

1 code implementation21 Mar 2024 Guopeng Li, Ming Qian, Gui-Song Xia

This paper investigates the effective utilization of unlabeled data for large-area cross-view geo-localization (CVGL), encompassing both unsupervised and semi-supervised settings.

Pattern retrieval of traffic congestion using graph-based associations of traffic domain-specific features

no code implementations28 Nov 2023 Tin T. Nguyen, Simeon C. Calvert, Guopeng Li, Hans van Lint

To effectively interpret retrieval outcomes, the paper proposes a graph-based approach (relation-graph) for the former component, in which fundamental traffic phenomena are encoded as nodes and their spatiotemporal relationships as edges.

Distil the informative essence of loop detector data set: Is network-level traffic forecasting hungry for more data?

1 code implementation31 Oct 2023 Guopeng Li, Victor L. Knoop, J. W. C., van Lint

To answer this, we propose an uncertainty-aware traffic forecasting framework to explore how many samples of loop data are truly effective for training forecasting models.

Towards Generic and Controllable Attacks Against Object Detection

1 code implementation23 Jul 2023 Guopeng Li, Yue Xu, Jian Ding, Gui-Song Xia

To this end, we propose a generic white-box attack, LGP (local perturbations with adaptively global attacks), to blind mainstream object detectors with controllable perturbations.
