Crossing Linguistic Horizons: Finetuning and Comprehensive Evaluation of Vietnamese Large Language Models

1 code implementation5 Mar 2024 Sang T. Truong, Duc Q. Nguyen, Toan Nguyen, Dong D. Le, Nhi N. Truong, Tho Quan, Sanmi Koyejo

Recent advancements in large language models (LLMs) have underscored their importance in the evolution of artificial intelligence.

Variational Flow Models: Flowing in Your Style

no code implementations5 Feb 2024 Kien Do, Duc Kieu, Toan Nguyen, Dang Nguyen, Hung Le, Dung Nguyen, Thin Nguyen

We introduce "posterior flows" - generalizations of "probability flows" to a broader class of stochastic processes not necessarily diffusion processes - and propose a systematic training-free method to transform the posterior flow of a "linear" stochastic process characterized by the equation Xt = at * X0 + st * X1 into a straight constant-speed (SC) flow, reminiscent of Rectified Flow.

Domain Generalisation via Risk Distribution Matching

1 code implementation28 Oct 2023 Toan Nguyen, Kien Do, Bao Duong, Thin Nguyen

Hence, we propose a compelling proposition: Minimising the divergences between risk distributions across training domains leads to robust invariance for DG.

Question-Context Alignment and Answer-Context Dependencies for Effective Answer Sentence Selection

no code implementations3 Jun 2023 Minh Van Nguyen, Kishan Kc, Toan Nguyen, Thien Huu Nguyen, Ankit Chadha, Thuy Vu

In this paper, we propose to improve the candidate scoring by explicitly incorporating the dependencies between question-context and answer-context into the final representation of a candidate.

Open-Vocabulary Affordance Detection in 3D Point Clouds

1 code implementation4 Mar 2023 Toan Nguyen, Minh Nhat Vu, An Vuong, Dzung Nguyen, Thieu Vo, Ngan Le, Anh Nguyen

In this paper, we present the Open-Vocabulary Affordance Detection (OpenAD) method, which is capable of detecting an unbounded number of affordances in 3D point clouds.

Causal Inference via Style Transfer for Out-of-distribution Generalisation

1 code implementation6 Dec 2022 Toan Nguyen, Kien Do, Duc Thanh Nguyen, Bao Duong, Thin Nguyen

A well-known existing causal inference method like back-door adjustment cannot be applied to remove spurious correlations as it requires the observation of confounders.

Skin Lesion Recognition with Class-Hierarchy Regularized Hyperbolic Embeddings

no code implementations13 Sep 2022 Zhen Yu, Toan Nguyen, Yaniv Gal, Lie Ju, Shekhar S. Chandra, Lei Zhang, Paul Bonnington, Victoria Mar, Zhiyong Wang, ZongYuan Ge

Accordingly, the learned prototypes preserve the semantic class relations in the embedding space and we can predict the label of an image by assigning its feature to the nearest hyperbolic class prototype.

Neural Machine Translation of Text from Non-Native Speakers

2 code implementations NAACL 2019 Antonios Anastasopoulos, Alison Lui, Toan Nguyen, David Chiang

Neural Machine Translation (NMT) systems are known to degrade when confronted with noisy data, especially when the system is trained only on clean data.

Kid on The Phone! Toward Automatic Detection of Children on Mobile Devices

no code implementations5 Aug 2018 Toan Nguyen, Aditi Roy, Nasir Memon

In this work, we present multiple techniques to automatically detect the presence of a child on a smart device, which could be used as the first step on such systems.
