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.

Residual Correction in Real-Time Traffic Forecasting

no code implementations12 Sep 2022 Daejin Kim, Youngin Cho, Dongmin Kim, Cheonbok Park, Jaegul Choo

Extensive experiments on METR-LA and PEMS-BAY demonstrate that our ResCAL can correctly capture the correlation of errors and correct the failures of various traffic forecasting models in event situations.

Normalized Convolutional Neural Network

1 code implementation11 May 2020 Dongsuk Kim, Geonhee Lee, Myungjae Lee, Shin Uk Kang, Dongmin Kim

The normalized process is similar to a normalization methods, but NCNN is more adapative to sliced-inputs and corresponding the convolutional kernel.
