Instance Segmentation under Occlusions via Location-aware Copy-Paste Data Augmentation

1 code implementation27 Oct 2023 Son Nguyen, Mikel Lainsa, Hung Dao, Daeyoung Kim, Giang Nguyen

Given the modest size of the dataset and the highly deformable nature of the objects to be segmented, this challenge demands the application of robust data augmentation techniques and wisely-chosen deep learning architectures.

Fairness-enhancing mixed effects deep learning improves fairness on in- and out-of-distribution clustered (non-iid) data

no code implementations4 Oct 2023 Adam Wang, Son Nguyen, Albert Montillo

MEDL separately quantifies cluster-invariant fixed effects (FE) and cluster-specific random effects (RE) through the introduction of: 1) a cluster adversary which encourages the learning of cluster-invariant FE, 2) a Bayesian neural network which quantifies the RE, and a mixing function combining the FE an RE into a mixed-effect prediction.

ARIST: An Effective API Argument Recommendation Approach

no code implementations11 Jun 2023 Son Nguyen, Cuong Tran Manh, Kien T. Tran, Tan M. Nguyen, Thu-Trang Nguyen, Kien-Tuan Ngo, Hieu Dinh Vo

To implement this idea in the recommendation process, ARIST combines program analysis (PA), language models (LMs), and several features specialized for the recommendation task which consider the functionality of formal parameters and the positional information of code elements (e. g., variables or method calls) in the given context.

TLETA: Deep Transfer Learning and Integrated Cellular Knowledge for Estimated Time of Arrival Prediction

no code implementations17 Jun 2022 Hieu Tran, Son Nguyen, I-Ling Yen, Farokh Bastani

Importantly, our transfer models only train the last layers to map the transferred knowledge, that reduces the training time significantly.

Reducing Catastrophic Forgetting in Neural Networks via Gaussian Mixture Approximation

no code implementations Pacific-Asia Conference on Knowledge Discovery and Data Mining 2022 Hoang Phan, Anh Phan Tuan, Son Nguyen, Ngo Van Linh, Khoat Than

Our paper studies the continual learning (CL) problems in which data comes in sequence and the trained models are expected to be capable of utilizing existing knowledge to solve new tasks without losing performance on previous ones.

IoT Data Discovery: Routing Table and Summarization Techniques

no code implementations21 Mar 2022 Hieu Tran, Son Nguyen, I-Ling Yen, Farokh Bastani

Specifically, as the first in the field, this paper investigates routing table designs and various compression techniques to support effective and space-efficient IoT data discovery routing.

Three-Way Deep Neural Network for Radio Frequency Map Generation and Source Localization

no code implementations23 Nov 2021 Kuldeep S. Gill, Son Nguyen, Myo M. Thein, Alexander M. Wyglinski

In this paper, we present a Generative Adversarial Network (GAN) machine learning model to interpolate irregularly distributed measurements across the spatial domain to construct a smooth radio frequency map (RFMap) and then perform localization using a deep neural network.

Into Summarization Techniques for IoT Data Discovery Routing

1 code implementation20 Jul 2021 Hieu Tran, Son Nguyen, I-Ling Yen, Farokh Bastani

Also, our approach outperforms DHT based approaches by 2 to 6 folds in terms of latency and traffic.

Price Discrimination in the Presence of Customer Loyalty and Differing Firm Costs

no code implementations16 Feb 2021 Theja Tulabandhula, Aris Ouksel, Son Nguyen

We study how loyalty behavior of customers and differing costs to produce undifferentiated products by firms can influence market outcomes.

Structured Dropout Variational Inference for Bayesian Neural Networks

no code implementations NeurIPS 2021 Son Nguyen, Duong Nguyen, Khai Nguyen, Khoat Than, Hung Bui, Nhat Ho

Approximate inference in Bayesian deep networks exhibits a dilemma of how to yield high fidelity posterior approximations while maintaining computational efficiency and scalability.

Improving Relational Regularized Autoencoders with Spherical Sliced Fused Gromov Wasserstein

2 code implementations ICLR 2021 Khai Nguyen, Son Nguyen, Nhat Ho, Tung Pham, Hung Bui

To improve the discrepancy and consequently the relational regularization, we propose a new relational discrepancy, named spherical sliced fused Gromov Wasserstein (SSFG), that can find an important area of projections characterized by a von Mises-Fisher distribution.

Does BLEU Score Work for Code Migration?

no code implementations12 Jun 2019 Ngoc Tran, Hieu Tran, Son Nguyen, Hoan Nguyen, Tien N. Nguyen

In this paper, we conducted an empirical study on BLEU score to (in)validate its suitability for the code migration task due to its inability to reflect the semantics of source code.
