OpenIncrement: A Unified Framework for Open Set Recognition and Deep Class-Incremental Learning

1 code implementation5 Oct 2023 Jiawen Xu, Claas Grohnfeldt, Odej Kao

In most works on deep incremental learning research, it is assumed that novel samples are pre-identified for neural network retraining.

Automated Antenna Testing Using Encoder-Decoder-based Anomaly Detection

no code implementations27 Nov 2021 Hans Hao-Hsun Hsu, Jiawen Xu, Ravi Sama, Matthias Kovatsch

A contour-based anomaly detector can then map the reconstruction error matrix to an anomaly score to identify faulty antenna arrays and increase the classification F-measure (F-M) by up to 46%.

PF-Net: Point Fractal Network for 3D Point Cloud Completion

2 code implementations CVPR 2020 Zitian Huang, Yikuan Yu, Jiawen Xu, Feng Ni, Xinyi Le

Unlike existing point cloud completion networks, which generate the overall shape of the point cloud from the incomplete point cloud and always change existing points and encounter noise and geometrical loss, PF-Net preserves the spatial arrangements of the incomplete point cloud and can figure out the detailed geometrical structure of the missing region(s) in the prediction.
