The Big Data Analysis Research Institute (Professor Park No-sung) published a total of 14 papers (12 authors in charge of Professor Park No-sung, 2 co-supervised) at this year's Top Tier Academic Conference in 2021. The research fields that account for a large part of the related research performance are largely the following three areas.

  • ● It shows world-class performance in physics-informed Neural Networks, Neural Ordinal Differential Equations and Neural Controlled Differential Equations, and time series data processing using them.
  • ● Generative Adversarial Networks-like generative models. In particular, it shows the world's best performance in the field of tabular data synthesis.
  • ● It also shows the highest level of performance in various recommendation fields. In particular, regarding recommendations, as a member of Naver's news recommendation algorithm review committee, it is currently verifying that there is no bias or error in Naver's recommendation system.

Among the research results in 2021, the summary and detailed research papers of 14 Toptier papers, including NeurIPS, KDD, ICML, ACL, WWW, and AAAI, are as follows.

In particular, 11 Attractive Neural Controlled Differential Equations studies on the list are invited by Professor Terry Lyons' research group at Oxford University in the UK, and Jin Seo-yeon (second semester of Ph.D.) plans to hold a seminar on November 3 with Oxford researchers. The promotional links for the seminar are as follows.

Professor Terry Lyons is a world-renowned scholar who won the Fields Medal of the Nobel Prize in Mathematics for Rough Path Theory and recently proposed groundbreaking methods such as Neural Controlled Differential Equations and Neural Rough Differential Equations in deep learning research.

In addition, Jeon Jin-sung (4th semester of Ph.D.) has produced top tier performance of 4 hesitant and 4 co-authors this year alone, and many studies are currently under review, showing extraordinary research results.
