Incremental Few-Shot Learning via Implanting and Compressing

no code implementations19 Mar 2022 Yiting Li, Haiyue Zhu, Xijia Feng, Zilong Cheng, Jun Ma, Cheng Xiang, Prahlad Vadakkepat, Tong Heng Lee

Specifically, in the \textbf{Implanting} step, we propose to mimic the data distribution of novel classes with the assistance of data-abundant base set, so that a model could learn semantically-rich features that are beneficial for discriminating between the base and other unseen classes.

Towards Generalized and Incremental Few-Shot Object Detection

no code implementations23 Sep 2021 Yiting Li, Haiyue Zhu, Jun Ma, Chek Sing Teo, Cheng Xiang, Prahlad Vadakkepat, Tong Heng Lee

We conduct experiments on both Pascal VOC and MS-COCO, which demonstrate that our method can effectively solve the problem of incremental few-shot detection and significantly improve the detection accuracy on both base and novel classes.

Few-Shot Object Detection via Classification Refinement and Distractor Retreatment

no code implementations CVPR 2021 Yiting Li, Haiyue Zhu, Yu Cheng, Wenxin Wang, Chek Sing Teo, Cheng Xiang, Prahlad Vadakkepat, Tong Heng Lee

The failure modes of FSOD are investigated that the performance degradation is mainly due to the classification incapability (false positives), which motivates us to address it from a novel aspect of hard example mining.

On Solar Photovoltaic Parameter Estimation: Global Optimality Analysis and a Simple Efficient Differential Evolution Method

1 code implementation16 Nov 2020 Shuhua Gao, Yunyi Zhao, Cheng Xiang, Yu Ming, Tan Kuan Tak, Tong Heng Lee

More attractively, the simple DE algorithm takes only a fraction of the runtime of state-of-the-art metaheuristic methods and is particularly preferable in time-sensitive applications.

e-TLD: Event-based Framework for Dynamic Object Tracking

1 code implementation2 Sep 2020 Bharath Ramesh, Shihao Zhang, Hong Yang, Andres Ussa, Matthew Ong, Garrick Orchard, Cheng Xiang

On the other hand, when the object re-enters the field-of-view of the camera, a data-driven, global sliding window detector locates the object for subsequent tracking.

A deep Convolutional Neural Network for topology optimization with strong generalization ability

no code implementations23 Jan 2019 Yiquan Zhang, Bo Peng, Xiaoyi Zhou, Cheng Xiang, Dalei Wang

The performance of the proposed method was evaluated by comparing its efficiency and accuracy with SIMP on a series of typical optimization problems.

DART: Distribution Aware Retinal Transform for Event-based Cameras

no code implementations30 Oct 2017 Bharath Ramesh, Hong Yang, Garrick Orchard, Ngoc Anh Le Thi, Shihao Zhang, Cheng Xiang

We introduce a generic visual descriptor, termed as distribution aware retinal transform (DART), that encodes the structural context using log-polar grids for event cameras.
