S3E: A Large-scale Multimodal Dataset for Collaborative SLAM

1 code implementation25 Oct 2022 Dapeng Feng, Yuhua Qi, Shipeng Zhong, Zhiqiang Chen, Yudu Jiao, Qiming Chen, Tao Jiang, Hongbo Chen

With the advanced request to employ a team of robots to perform a task collaboratively, the research community has become increasingly interested in collaborative simultaneous localization and mapping.

Simultaneous Localization and Mapping

Differentiable, learnable, regionalized process-based models with physical outputs can approach state-of-the-art hydrologic prediction accuracy

no code implementations28 Mar 2022 Dapeng Feng, Jiangtao Liu, Kathryn Lawson, Chaopeng Shen

Without using an ensemble or post-processor, {\delta} models can obtain a median Nash Sutcliffe efficiency of 0. 732 for 671 basins across the USA for the Daymet forcing dataset, compared to 0. 748 from a state-of-the-art LSTM model with the same setup.

The data synergy effects of time-series deep learning models in hydrology

no code implementations6 Jan 2021 Kuai Fang, Daniel Kifer, Kathryn Lawson, Dapeng Feng, Chaopeng Shen

We hypothesize that DL models automatically adjust their internal representations to identify commonalities while also providing sufficient discriminatory information to the model.

Exploring Geometry-Aware Contrast and Clustering Harmonization for Self-Supervised 3D Object Detection

no code implementations ICCV 2021 Hanxue Liang, Chenhan Jiang, Dapeng Feng, Xin Chen, Hang Xu, Xiaodan Liang, Wei zhang, Zhenguo Li, Luc van Gool

Here we present a novel self-supervised 3D Object detection framework that seamlessly integrates the geometry-aware contrast and clustering harmonization to lift the unsupervised 3D representation learning, named GCC-3D.

Prediction in ungauged regions with sparse flow duration curves and input-selection ensemble modeling

1 code implementation26 Nov 2020 Dapeng Feng, Kathryn Lawson, Chaopeng Shen

While long short-term memory (LSTM) models have demonstrated stellar performance with streamflow predictions, there are major risks in applying these models in contiguous regions with no gauges, or predictions in ungauged regions (PUR) problems.

From calibration to parameter learning: Harnessing the scaling effects of big data in geoscientific modeling

no code implementations30 Jul 2020 Wen-Ping Tsai, Dapeng Feng, Ming Pan, Hylke Beck, Kathryn Lawson, Yuan Yang, Jiangtao Liu, Chaopeng Shen

The behaviors and skills of models in many geosciences (e. g., hydrology and ecosystem sciences) strongly depend on spatially-varying parameters that need calibration.

Enhancing streamflow forecast and extracting insights using long-short term memory networks with data integration at continental scales

no code implementations18 Dec 2019 Dapeng Feng, Kuai Fang, Chaopeng Shen

DI was most beneficial in regions with high flow autocorrelation: it greatly reduced baseflow bias in groundwater-dominated western basins and also improved peak prediction for basins with dynamical surface water storage, such as the Prairie Potholes or Great Lakes regions.
