Towards Explainable Collaborative Filtering with Taste Clusters Learning

2023

Collaborative Filtering (CF) is a widely used and effective technique for recommender systems. In recent decades, there have been significant advancements in latent embedding-based CF methods for improved accuracy, such as matrix factorization, neural collaborative …

Demonstration of a Ditherless Auto Bias Control for Optical IQ Modulator using Genetic Algorithm and Greedy Method

2024

We experimentally demonstrated the ditherless auto bias control operation for a dual-polarization IQ modulator using genetic algorithm-based control for initialization process and greedy method of fine control for tracking process. In the actual modulator measurement, …
