On-Off Pattern Encoding and Path-Count Encoding as Deep Neural Network Representations

no code implementations17 Jan 2024 Euna Jung, Jaekeol Choi, Eunggu Yun, Wonjong Rhee

Specifically, we consider \textit{On-Off pattern} and \textit{PathCount} for investigating how information is stored in deep representations.

Evaluating Feature Attribution Methods for Electrocardiogram

1 code implementation23 Nov 2022 Jangwon Suh, Jimyeong Kim, Euna Jung, Wonjong Rhee

The performance of cardiac arrhythmia detection with electrocardiograms(ECGs) has been considerably improved since the introduction of deep learning models.

Isotropic Representation Can Improve Dense Retrieval

1 code implementation1 Sep 2022 Euna Jung, Jungwon Park, Jaekeol Choi, Sungyoon Kim, Wonjong Rhee

In particular, many of the high-performing dense retrieval models evaluate representations of query and document using BERT, and subsequently apply a cosine-similarity based scoring to determine the relevance.

Finding Inverse Document Frequency Information in BERT

no code implementations24 Feb 2022 Jaekeol Choi, Euna Jung, Sungjun Lim, Wonjong Rhee

The traditional approach, however, is being rapidly replaced by Neural Ranking Models (NRMs) that can exploit semantic features.

Semi-Siamese Bi-encoder Neural Ranking Model Using Lightweight Fine-Tuning

1 code implementation28 Oct 2021 Euna Jung, Jaekeol Choi, Wonjong Rhee

The results confirm that both lightweight fine-tuning and semi-Siamese are considerably helpful for improving BERT-based bi-encoders.

Improving Bi-encoder Document Ranking Models with Two Rankers and Multi-teacher Distillation

1 code implementation11 Mar 2021 Jaekeol Choi, Euna Jung, Jangwon Suh, Wonjong Rhee

When monoBERT is used as the cross-encoder teacher, together with either TwinBERT or ColBERT as the bi-encoder teacher, TRMD produces a student bi-encoder that performs better than the corresponding baseline bi-encoder.

Short-term Traffic Prediction with Deep Neural Networks: A Survey

no code implementations28 Aug 2020 Kyungeun Lee, Moonjung Eo, Euna Jung, Yoonjin Yoon, Wonjong Rhee

2) We briefly explain a wide range of DNN techniques from the earliest networks, including Restricted Boltzmann Machines, to the most recent, including graph-based and meta-learning networks.
