Learning-Augmented K-Means Clustering Using Dimensional Reduction

no code implementations6 Jan 2024 Issam K. O Jabari, Shofiyah, Pradiptya Kahvi S, Novi Nur Putriwijaya, Novanto Yudistira

Learning augmented is a machine learning concept built to improve the performance of a method or model, such as enhancing its ability to predict and generalize data or features, or testing the reliability of the method by introducing noise and other factors.

Mixture of Self-Supervised Learning

1 code implementation27 Jul 2023 Aristo Renaldo Ruslim, Novanto Yudistira, Budi Darma Setiawan

Therefore, we propose the Gated Self-Supervised Learning method to improve image classification which use more than one transformation as pretext task and uses the Mixture of Expert architecture as a gating network in combining each pretext task so that the model automatically can study and focus more on the most useful augmentations for classification.
