Enhancing Long-Term Recommendation with Bi-level Learnable Large Language Model Planning

no code implementations29 Feb 2024 Wentao Shi, Xiangnan He, Yang Zhang, Chongming Gao, Xinyue Li, Jizhi Zhang, Qifan Wang, Fuli Feng

To achieve this, we propose a Bi-level Learnable LLM Planner framework, which combines macro-learning and micro-learning through a hierarchical mechanism.

Exploration of Learned Lifting-Based Transform Structures for Fully Scalable and Accessible Wavelet-Like Image Compression

no code implementations29 Feb 2024 Xinyue Li, Aous Naman, David Taubman

Moreover, we demonstrate that employing more learned lifting steps and more layers in each learned lifting operator do not contribute strongly to the compression performance.

Iris Liveness Detection Competition (LivDet-Iris) -- The 2023 Edition

no code implementations6 Oct 2023 Patrick Tinsley, Sandip Purnapatra, Mahsa Mitcheff, Aidan Boyd, Colton Crum, Kevin Bowyer, Patrick Flynn, Stephanie Schuckers, Adam Czajka, Meiling Fang, Naser Damer, Xingyu Liu, Caiyong Wang, Xianyun Sun, Zhaohua Chang, Xinyue Li, Guangzhe Zhao, Juan Tapia, Christoph Busch, Carlos Aravena, Daniel Schulz

New elements in this fifth competition include (1) GAN-generated iris images as a category of presentation attack instruments (PAI), and (2) an evaluation of human accuracy at detecting PAI as a reference benchmark.

Assessing cognitive function among older adults using machine learning and wearable device data: a feasibility study

no code implementations28 Aug 2023 Collin Sakal, Tingyou Li, Juan Li, Xinyue Li

Timely implementation of interventions to slow cognitive decline among older adults requires accurate monitoring to detect changes in cognitive function.

Camouflaged Object Detection with Feature Grafting and Distractor Aware

1 code implementation8 Jul 2023 Yuxuan Song, Xinyue Li, Lin Qi

In order to better explore the advantages of the two encoders, we design a cross-attention-based Feature Grafting Module to graft features extracted from Transformer branch into CNN branch, after which the features are aggregated in the Feature Fusion Module.

Under-Parameterized Double Descent for Ridge Regularized Least Squares Denoising of Data on a Line

no code implementations24 May 2023 Rishi Sonthalia, Xinyue Li, Bochao Gu

For larger values of $\mu$, we observe that the curve for the norm of the estimator has a peak but that this no longer translates to a peak in the generalization error.

PLOT: Prompt Learning with Optimal Transport for Vision-Language Models

1 code implementation3 Oct 2022 Guangyi Chen, Weiran Yao, Xiangchen Song, Xinyue Li, Yongming Rao, Kun Zhang

To solve this problem, we propose to apply optimal transport to match the vision and text modalities.
