DiverseDream: Diverse Text-to-3D Synthesis with Augmented Text Embedding

no code implementations2 Dec 2023 Uy Dieu Tran, Minh Luu, Phong Nguyen, Janne Heikkila, Khoi Nguyen, Binh-Son Hua

Text-to-3D synthesis has recently emerged as a new approach to sampling 3D models by adopting pretrained text-to-image models as guiding visual priors.

EmbryosFormer: Deformable Transformer and Collaborative Encoding-Decoding for Embryos Stage Development Classification

1 code implementation7 Oct 2022 Tien-Phat Nguyen, Trong-Thang Pham, Tri Nguyen, Hieu Le, Dung Nguyen, Hau Lam, Phong Nguyen, Jennifer Fowler, Minh-Triet Tran, Ngan Le

The transformer expanding path models the temporal coherency between embryo images to ensure monotonic non-decreasing constraint and is optimized by a segmentation head.

SP-GPT2: Semantics Improvement in Vietnamese Poetry Generation

1 code implementation10 Oct 2021 Tuan Nguyen, Hanh Pham, Truong Bui, Tan Nguyen, Duc Luong, Phong Nguyen

Both automatic and human evaluation demonstrated that our approach can generate poems that have better cohesion without losing the quality due to additional loss.

Lightweight Monocular Depth with a Novel Neural Architecture Search Method

no code implementations25 Aug 2021 Lam Huynh, Phong Nguyen, Jiri Matas, Esa Rahtu, Janne Heikkila

This paper presents a novel neural architecture search method, called LiDNAS, for generating lightweight monocular depth estimation models.

Monocular Depth Estimation Primed by Salient Point Detection and Normalized Hessian Loss

no code implementations25 Aug 2021 Lam Huynh, Matteo Pedone, Phong Nguyen, Jiri Matas, Esa Rahtu, Janne Heikkila

In addition, we introduce a normalized Hessian loss term invariant to scaling and shear along the depth direction, which is shown to substantially improve the accuracy.

RGBD-Net: Predicting color and depth images for novel views synthesis

no code implementations29 Nov 2020 Phong Nguyen, Animesh Karnewar, Lam Huynh, Esa Rahtu, Jiri Matas, Janne Heikkila

We propose a new cascaded architecture for novel view synthesis, called RGBD-Net, which consists of two core components: a hierarchical depth regression network and a depth-aware generator network.

A Multi-Objective Learning to re-Rank Approach to Optimize Online Marketplaces for Multiple Stakeholders

no code implementations2 Aug 2017 Phong Nguyen, John Dines, Jan Krasnodebski

However these systems are most often designed to address the objective of one single stakeholder, typically, in online commerce, the consumers whose input and purchasing decisions ultimately determine the success of the recommendation systems.

Factorizing LambdaMART for cold start recommendations

no code implementations4 Nov 2015 Phong Nguyen, Jun Wang, Alexandros Kalousis

Motivated by the fact that very often the users' and items' descriptions as well as the preference behavior can be well summarized by a small number of hidden factors, we propose a novel algorithm, LambdaMART Matrix Factorization (LambdaMART-MF), that learns a low rank latent representation of users and items using gradient boosted trees.
