Convolutional Bayesian Filtering

no code implementations30 Mar 2024 Wenhan Cao, Shiqi Liu, Chang Liu, Zeyu He, Stephen S. -T. Yau, Shengbo Eben Li

In this paper, we find that by adding an additional event that stipulates an inequality condition, we can transform the conditional probability into a special integration that is analogous to convolution.

Towards Detecting AI-Generated Text within Human-AI Collaborative Hybrid Texts

no code implementations6 Mar 2024 Zijie Zeng, Shiqi Liu, Lele Sha, Zhuang Li, Kaixun Yang, Sannyuya Liu, Dragan Gašević, Guanliang Chen

Our empirical findings highlight (1) detecting AI-generated sentences in hybrid texts is overall a challenging task because (1. 1) human writers' selecting and even editing AI-generated sentences based on personal preferences adds difficulty in identifying the authorship of segments; (1. 2) the frequent change of authorship between neighboring sentences within the hybrid text creates difficulties for segment detectors in identifying authorship-consistent segments; (1. 3) the short length of text segments within hybrid texts provides limited stylistic cues for reliable authorship determination; (2) before embarking on the detection process, it is beneficial to assess the average length of segments within the hybrid text.

Understanding Pan-Sharpening via Generalized Inverse

no code implementations4 Oct 2023 Shiqi Liu, Yutong Bai, Xinyang Han, Alan Yuille

By the generalized inverse theory, we derived two forms of general inverse matrix formulations that can correspond to the two prominent classes of Pan-sharpening methods, that is, component substitution and multi-resolution analysis methods.

Continual Vision-based Reinforcement Learning with Group Symmetries

no code implementations21 Oct 2022 Shiqi Liu, Mengdi Xu, Piede Huang, Yongkang Liu, Kentaro Oguchi, Ding Zhao

Continual reinforcement learning aims to sequentially learn a variety of tasks, retaining the ability to perform previously encountered tasks while simultaneously developing new policies for novel tasks.

Automatically eliminating seam lines with Poisson editing in complex relative radiometric normalization mosaicking scenarios

no code implementations14 Jun 2021 Shiqi Liu, Jie Lian, Xuchen Zhan, Cong Liu, Yuze Tian, Hongwei Duan

Relative radiometric normalization (RRN) mosaicking among multiple remote sensing images is crucial for the downstream tasks, including map-making, image recognition, semantic segmentation, and change detection.

Understanding Self-Paced Learning under Concave Conjugacy Theory

no code implementations21 May 2018 Shiqi Liu, Zilu Ma, Deyu Meng

By simulating the easy-to-hard learning manners of humans/animals, the learning regimes called curriculum learning~(CL) and self-paced learning~(SPL) have been recently investigated and invoked broad interests.

Preliminary theoretical troubleshooting in Variational Autoencoder

no code implementations ICLR 2018 Shiqi Liu, Qian Zhao, Xiangyong Cao, Deyu Meng, Zilu Ma, Tao Yu

This paper tries to preliminarily address VAE's intrinsic dimension, real factor, disentanglement and indicator issues theoretically in the idealistic situation and implementation issue practically through noise modeling perspective in the realistic case.
