MOTIF: Contextualized Images for Complex Words to Improve Human Reading

no code implementations LREC 2022 Xintong Wang, Florian Schneider, Özge Alacam, Prateek Chaudhury, Chris Biemann

In this respect, several traditional NLP approaches can assist L2 readers in text comprehension processes, such as simplifying text or giving dictionary descriptions for complex words.

Mitigating Hallucinations in Large Vision-Language Models with Instruction Contrastive Decoding

no code implementations27 Mar 2024 Xintong Wang, Jingheng Pan, Liang Ding, Chris Biemann

Our method is inspired by our observation that what we call disturbance instructions significantly exacerbate hallucinations in multimodal fusion modules.

AnimatableDreamer: Text-Guided Non-rigid 3D Model Generation and Reconstruction with Canonical Score Distillation

no code implementations6 Dec 2023 Xinzhou Wang, Yikai Wang, Junliang Ye, Zhengyi Wang, Fuchun Sun, Pengkun Liu, Ling Wang, Kai Sun, Xintong Wang, Bin He

At its core, AnimatableDreamer is equipped with our novel optimization design dubbed Canonical Score Distillation (CSD), which simplifies the generation dimension from 4D to 3D by denoising over different frames in the time-varying camera spaces while conducting the distillation process in a unique canonical space shared per video.

Efficient Bayesian inference using physics-informed invertible neural networks for inverse problems

no code implementations25 Apr 2023 Xiaofei Guan, Xintong Wang, Hao Wu, Zihao Yang, Peng Yu

Simultaneously, the INN is designed to partition the parameter vector linked to the input physical field into two distinct components: the expansion coefficients representing the forward problem solution and the Gaussian latent noise.

Federated Semi-Supervised Learning with Class Distribution Mismatch

no code implementations29 Oct 2021 Zhiguo Wang, Xintong Wang, Ruoyu Sun, Tsung-Hui Chang

Similar to that encountered in federated supervised learning, class distribution of labeled/unlabeled data could be non-i. i. d.

Towards Multi-Modal Text-Image Retrieval to improve Human Reading

no code implementations NAACL 2021 Florian Schneider, {\"O}zge Ala{\c{c}}am, Xintong Wang, Chris Biemann

In primary school, children{'}s books, as well as in modern language learning apps, multi-modal learning strategies like illustrations of terms and phrases are used to support reading comprehension.

Cross-dataset Person Re-Identification Using Similarity Preserved Generative Adversarial Networks

no code implementations11 Jun 2018 Jianming Lv, Xintong Wang

Meanwhile, SimPGAN uses the similarity consistency loss, which is measured by a siamese deep convolutional neural network, to preserve the similarity of the transformed images of the same person.
