Robust MAML: Prioritization task buffer with adaptive learning process for model-agnostic meta-learning

no code implementations15 Mar 2021 Thanh Nguyen, Tung Luu, Trung Pham, Sanzhar Rakhimkul, Chang D. Yoo

Model agnostic meta-learning (MAML) is a popular state-of-the-art meta-learning algorithm that provides good weight initialization of a model given a variety of learning tasks.

Modality Shifting Attention Network for Multi-modal Video Question Answering

no code implementations CVPR 2020 Junyeong Kim, Minuk Ma, Trung Pham, Kyung-Su Kim, Chang D. Yoo

To this end, MSAN is based on (1) the moment proposal network (MPN) that attempts to locate the most appropriate temporal moment from each of the modalities, and also on (2) the heterogeneous reasoning network (HRN) that predicts the answer using an attention mechanism on both modalities.

Efficient Dense Point Cloud Object Reconstruction using Deformation Vector Fields

no code implementations ECCV 2018 Kejie Li, Trung Pham, Huangying Zhan, Ian Reid

Given a single image at an arbitrary viewpoint, a CNN predicts multiple surfaces, each in a canonical location relative to the object.

Bayesian Semantic Instance Segmentation in Open Set World

no code implementations ECCV 2018 Trung Pham, Vijay Kumar B G, Thanh-Toan Do, Gustavo Carneiro, Ian Reid

In this paper, we present a novel open-set semantic instance segmentation approach capable of segmenting all known and unknown object classes in images, based on the output of an object detector trained on known object classes.

Binary Constrained Deep Hashing Network for Image Retrieval without Manual Annotation

no code implementations21 Feb 2018 Thanh-Toan Do, Tuan Hoang, Dang-Khoa Le Tan, Trung Pham, Huu Le, Ngai-Man Cheung, Ian Reid

However, training deep hashing networks for the task is challenging due to the binary constraints on the hash codes, the similarity preserving property, and the requirement for a vast amount of labelled images.
