Bag of Tricks for In-Distribution Calibration of Pretrained Transformers

1 code implementation13 Feb 2023 Jaeyoung Kim, Dongbin Na, Sungchul Choi, Sungbin Lim

We find that the ensemble model overfitted to the training set shows sub-par calibration performance and also observe that PLMs trained with confidence penalty loss have a trade-off between calibration and accuracy.

Hybrid Machine Learning Approach to Popularity Prediction of Newly Released Contents for Online Video Streaming Service

no code implementations28 Jan 2019 Hongjun Jeon, Wonchul Seo, Eunjeong Lucy Park, Sungchul Choi

Our model uses metadata for contents for prediction, so we use categorical embedding techniques to solve the sparsity of categorical variables and make them learn efficiently for the deep neural net model.
