Self-Supervised Contrastive Learning for Long-term Forecasting

1 code implementation3 Feb 2024 Junwoo Park, Daehoon Gwak, Jaegul Choo, Edward Choi

To this end, our contrastive loss incorporates global autocorrelation held in the whole time series, which facilitates the construction of positive and negative pairs in a self-supervised manner.

Deep Imbalanced Time-series Forecasting via Local Discrepancy Density

1 code implementation27 Feb 2023 Junwoo Park, Jungsoo Lee, Youngin Cho, Woncheol Shin, Dongmin Kim, Jaegul Choo, Edward Choi

Based on our findings, we propose a reweighting framework that down-weights the losses incurred by abrupt changes and up-weights those by normal states.

Enemy Spotted: in-game gun sound dataset for gunshot classification and localization

1 code implementation12 Oct 2022 Junwoo Park, Youngwoo Cho, Gyuhyeon Sim, Hojoon Lee, Jaegul Choo

By exploiting the advantage of the game environment, we construct a gunshot dataset, namely BGG, for the firearm classification and gunshot localization tasks.

What and Where to Translate: Local Mask-based Image-to-Image Translation

no code implementations9 Jun 2019 Wonwoong Cho, Seunghwan Choi, Junwoo Park, David Keetae Park, Tao Qin, Jaegul Choo

First, those methods extract style from an entire exemplar which includes noisy information, which impedes a translation model from properly extracting the intended style of the exemplar.
