LCM: Locally Constrained Compact Point Cloud Model for Masked Point Modeling

no code implementations27 May 2024 Yaohua Zha, Naiqi Li, Yanzi Wang, Tao Dai, Hang Guo, Bin Chen, Zhi Wang, Zhihao Ouyang, Shu-Tao Xia

Considering the varying information density between masked and unmasked patches in the decoder inputs of MPM, we introduce a locally constrained Mamba-based decoder.

CALF: Aligning LLMs for Time Series Forecasting via Cross-modal Fine-Tuning

2 code implementations12 Mar 2024 Peiyuan Liu, Hang Guo, Tao Dai, Naiqi Li, Jigang Bao, Xudong Ren, Yong Jiang, Shu-Tao Xia

Unlike existing methods that focus on training models from a single modal of time series input, large language models (LLMs) based MTSF methods with cross-modal text and time series input have recently shown great superiority, especially with limited temporal data.

MambaIR: A Simple Baseline for Image Restoration with State-Space Model

1 code implementation23 Feb 2024 Hang Guo, Jinmin Li, Tao Dai, Zhihao Ouyang, Xudong Ren, Shu-Tao Xia

In this way, our MambaIR takes advantage of the local pixel similarity and reduces the channel redundancy.

AdaptIR: Parameter Efficient Multi-task Adaptation for Pre-trained Image Restoration Models

1 code implementation12 Dec 2023 Hang Guo, Tao Dai, Yuanchao Bai, Bin Chen, Shu-Tao Xia, Zexuan Zhu

Recently, Parameter Efficient Transfer Learning (PETL) offers an efficient alternative solution to full fine-tuning, yet still faces great challenges for pre-trained image restoration models, due to the diversity of different degradations.

One-stage Low-resolution Text Recognition with High-resolution Knowledge Transfer

1 code implementation5 Aug 2023 Hang Guo, Tao Dai, Mingyan Zhu, Guanghao Meng, Bin Chen, Zhi Wang, Shu-Tao Xia

Current solutions for low-resolution text recognition (LTR) typically rely on a two-stage pipeline that involves super-resolution as the first stage followed by the second-stage recognition.

Dissecting Local Properties of Adversarial Examples

no code implementations29 Sep 2021 Lu Chen, Renjie Chen, Hang Guo, Yuan Luo, Quanshi Zhang, Yisen Wang

Adversarial examples have attracted significant attention over the years, yet a sufficient understanding is in lack, especially when analyzing their performances in combination with adversarial training.

Peek Inside the Closed World: Evaluating Autoencoder-Based Detection of DDoS to Cloud

no code implementations11 Dec 2019 Hang Guo, Xun Fan, Anh Cao, Geoff Outhred, John Heidemann

We show that our models detect nearly all malicious flows for 2 of the 4 cloud IPs under attack (at least 99. 99%) and detect most malicious flows (94. 75% and 91. 37%) for the remaining 2 IPs.
