Latest Patents

Jeong Whan Choi holds a patent titled "Apparatus and method for recommending collaborative filtering based on learnable-time ordinary differential equation." This patent describes a collaborative filtering recommending apparatus that includes an initial-embedding generation module. This module is designed to generate first and second initial embeddings. Additionally, it features a dual co-evolving ordinary differential equation module that comprises first and second ordinary differential equation processing members. These members repeat a process of receiving first and second previous embeddings and outputting first and second subsequent embeddings through mutual influence as learning time elapses. The final-embedding generation module is responsible for generating a first final embedding by cumulative summing the first previous and subsequent embeddings, and a second final embedding by cumulative summing the second previous and subsequent embeddings.
