Multi-Scale Finetuning for Encoder-based Time Series Foundation Models

NeurIPS 2025poster

Time series foundation models (TSFMs) demonstrate impressive zero-shot performance for time series forecasting. However, an important yet underexplored challenge is how to effectively finetune TSFMs on specific downstream tasks. While naive finetuning can yield performance gains, we argue that it fa…

Class-Incremental Learning on Multivariate Time Series Via Shape-Aligned Temporal Distillation

ICASSP 2023accepted

Class-incremental learning (CIL) on multivariate time series (MTS) is an important yet understudied problem. Based on practical privacy-sensitive circumstances, we propose a novel distillation-based strategy using a single-headed classifier without saving historical samples. We propose to exploit So…

Versatile LiDAR-Inertial Odometry With SE(2) Constraints for Ground Vehicles

RA-L 2023

LiDAR SLAM has become one of the major localization systems for ground vehicles since LiDAR Odometry And Mapping (LOAM). Many extension works on LOAM mainly leverage one specific constraint to improve the performance, e.g., information from on-board sensors such as loop closure and inertial state; p

Investigating Robustness of Biological vs. Backprop Based Learning

ICASSP 2022accepted

Robustness of learning algorithms remains an important problem to be solved from both the perspective of adversarial attacks and improving generalization. In this work, we investigate the robustness of biologically inspired Hebbian learning algorithm in depth. We find that Hebbian learning based alg…

Robust Visual Tracking Using Oblique Random Forests

CVPR 2017poster

Random forest has emerged as a powerful classification technique with promising results in various vision tasks including image classification, pose estimation and object detection. However, current techniques have shown little improvements in visual tracking as they mostly rely on piece wise orthog…
