Convolutional Lie Operator for Sentence Classification
Daniela N. Rim, Heeyoul Choi
Traditional Convolutional Neural Networks have been successful in capturing local, position-invariant features in text, but their capacity to model complex transformation within la…
Dynamic Preference Multi-Objective Reinforcement Learning for Internet Network Management
DongNyeong Heo, Daniela Noemi Rim, Heeyoul Choi
An internet network service provider manages its network with multiple objectives, such as high quality of service (QoS) and minimum computing resource usage. To achieve these obje…
Harnessing EHRs for Diffusion-based Anomaly Detection on Chest X-rays
Harim Kim, Yuhan Wang, Minkyu Ahn +3
Unsupervised anomaly detection (UAD) in medical imaging is crucial for identifying pathological abnormalities without requiring extensive labeled data. However, existing diffusion-…
Data Augmentation With Back translation for Low Resource languages: A case of English and Luganda
Richard Kimera, Dongnyeong Heo, Daniela N. Rim +1
In this paper,we explore the application of Back translation (BT) as a semi-supervised technique to enhance Neural Machine Translation(NMT) models for the English-Luganda language…
Generalized Probabilistic Attention Mechanism in Transformers
DongNyeong Heo, Heeyoul Choi
The Transformer architecture has become widely adopted due to its demonstrated success, attributed to the attention mechanism at its core. Despite these successes, the attention me…
N-gram Prediction and Word Difference Representations for Language Modeling
DongNyeong Heo, Daniela Noemi Rim, Heeyoul Choi
Causal language modeling (CLM) serves as the foundational framework underpinning remarkable successes of recent large language models (LLMs). Despite its success, the training appr…
