Structured factor copulas for modeling the systemic risk of European and United States banks

no code implementations7 Jan 2024 Hoang Nguyen, Audronė Virbickaitė, M. Concepción Ausín, Pedro Galeano

In this paper, we employ Credit Default Swaps (CDS) to model the joint and conditional distress probabilities of banks in Europe and the U. S. using factor copulas.

LVM-Med: Learning Large-Scale Self-Supervised Vision Models for Medical Imaging via Second-order Graph Matching

1 code implementation NeurIPS 2023 Duy M. H. Nguyen, Hoang Nguyen, Nghiem T. Diep, Tan N. Pham, Tri Cao, Binh T. Nguyen, Paul Swoboda, Nhat Ho, Shadi Albarqouni, Pengtao Xie, Daniel Sonntag, Mathias Niepert

While pre-trained deep networks on ImageNet and vision-language foundation models trained on web-scale data are prevailing approaches, their effectiveness on medical tasks is limited due to the significant domain shift between natural and medical images.

Joint Self-Supervised Image-Volume Representation Learning with Intra-Inter Contrastive Clustering

no code implementations4 Dec 2022 Duy M. H. Nguyen, Hoang Nguyen, Mai T. N. Truong, Tri Cao, Binh T. Nguyen, Nhat Ho, Paul Swoboda, Shadi Albarqouni, Pengtao Xie, Daniel Sonntag

Recent breakthroughs in self-supervised learning (SSL) offer the ability to overcome the lack of labeled training samples by learning feature representations from unlabeled data.

Fall detection using multimodal data

no code implementations12 May 2022 Thao V. Ha, Hoang Nguyen, Son T. Huynh, Trung T. Nguyen, Binh T. Nguyen

In recent years, the occurrence of falls has increased and has had detrimental effects on older adults.

Vector autoregression models with skewness and heavy tails

no code implementations24 May 2021 Sune Karlsson, Stepan Mazur, Hoang Nguyen

We propose a general class of generalized hyperbolic skew Student's t distribution with stochastic volatility for the error term in the VAR model that allows us to take into account skewness and heavy tails.

Dynamic Semantic Matching and Aggregation Network for Few-shot Intent Detection

1 code implementation Findings of the Association for Computational Linguistics 2020 Hoang Nguyen, Chenwei Zhang, Congying Xia, Philip S. Yu

Although recent works demonstrate that multi-level matching plays an important role in transferring learned knowledge from seen training classes to novel testing classes, they rely on a static similarity measure and overly fine-grained matching components.

Neural Multi-task Text Normalization and Sanitization with Pointer-Generator

no code implementations WS 2020 Hoang Nguyen, S Cavallari, ro

Its generator effectively captures linguistic context during normalization and sanitization while its pointer dynamically preserves the entities that are generally missing in the vocabulary.

CG-BERT: Conditional Text Generation with BERT for Generalized Few-shot Intent Detection

no code implementations4 Apr 2020 Congying Xia, Chenwei Zhang, Hoang Nguyen, Jiawei Zhang, Philip Yu

In this paper, we formulate a more realistic and difficult problem setup for the intent detection task in natural language understanding, namely Generalized Few-Shot Intent Detection (GFSID).
