Sanghyuk Chun (He/Him)

Sanghyuk Chun

I am a Ph.D. student at Princeton University advised by Professor Olga Russakovsky. My current research interest lies on the domains of machine learning, multi-modal learning (e.g., vision-language, language-audio, and audio-visual), trustworthy ML, and computer vision.

Prior to Princeton, I served as a lead research scientist at ML Research team in NAVER AI Lab (from 2018 to 2025). I held a position as a research engineer at KAKAO Corp from 2016 to 2018, where my work focused on recommendation systems and machine learning applications.

Code and Data

Datasets

  • CUB v2 and OpenImages 30k [C5] [J1]: These datasets were designed and collected for the WSOL evaluation project. We newly collected bird images for CUB v2 (200 classes) and re-organize OpenImages V5 for OpenImages 30k (100 classes)
  • Biased MNIST, 9-Class ImageNet and ImageNet cluster labels [C6]: We proposed these datasets for measuring how ML models can be generalized to bias shift. Biased MNIST is a synthetic dataset based on MNIST, while each image has background colors which highly correlates with the labels (controllable). ImageNet-9 contains 9 super-classes (dog, cat, frog, turtle, bird, monkey, fish, crab, insect) and 57k training samples. We also proposes "unbiased accuracy" by using cluster labels (K=9), which empicially matches to Shell, Grass, Close-up, Eye, Human, Sand and Mammal.
  • CUB Caption [C11]: CUB was not majorly used for image-text matching (ITM) retrieval. However, while doing the PCME project, we proposed to use the CUB dataset as a ITM benchmark for measuring the impact of many-to-many correspondence; if an image and a description are in the same class, then we treat it as "positive" otherwise "negative". We carefully devide the training-validation (150 classes) and test splits (50 classes) following Xian et al. 2017.
  • ECCV Caption [C21]: Although CUB Caption can evaluate the impact of many-to-many correspondence in ITM, this dataset is still "synthetic". For a more practical usage, we proposed the ECCV Caption benchmark, by correcting the false negatives (FNs) in the MS-COCO Caption dataset. By machine and human annotators, we collected x8.47 positive images and x3.58 positive captions compared to the original COCO Caption.
  • RoCOCO [W9]: Is an ITM model robust to a malicious manipulation on captions or images? Here, we investigated the impact of altered captions (same concept, different concept, rand voca attack, and dangerous word) and mixed images. Even state-of-the-art ITM models showed substantial performance degradations on our benchmark.

Kakao Advanced Recommendation Technology (ART) team (2016 ~ 2018)

  • Recommender Systems (Kakao services)

    Feb. 2016 - Feb. 2018

    • I developed and maintained a large-scale real-time recommender system (Toros [PyCon Talk] [AI Report]) for various services in Daum and Kakao. I mainly worked with content-based representation modeling (for textual, visual, and musical data), collaborative filtering modeling, user embedding, user clustering, and ranking system based on Multi-armed Bandit.
    • Textual domain: Daum News similar article recommendation, Brunch (blog service) similar post recommendation, Daum Cafe (community service) hit item recommendation.
    • Visual domain: Daum Webtoon and Kakao Page similar item recommendation, video recommendation for a news article (cross-domain recommendation).
    • Audio domain: music recommendation for Kakao Mini (smart speaker), Melon and Kakao Music.
    • Online to offline: Kakao Hairshop style recommendation.
  • System overview.
    Personalized Push Notification with User History (Daum, Kakao Page)

    Deployed in 2017

    • The mobile push service (or alert system) is widely-used in mobile applications to attain a high user retention rate. However, a freqeunt push notification makes a user feel fatigue, resulting on the application removal. Usually, the push notification system is a rule-based system, and managed by human labor. In this project, we researched and developed a personalized push notification system based on user activity and interests. The system has been applied to Daum an Kakao Page mobile applications. More details are in our paper.
  • Large-Scale Item Categorization in e-Commerce (Daum Shopping)

    Deployed in 2017

    • An accurate categorization helps users to search desired items in e-Commerce based on the category, e.g., clothes / shoes / sneakers. However, the categorization is usually performed based on rule-based systems or human labor, which leads to low coverage of categorized items. Even the automatic item categorization is difficult due to its web-scale data size, the highly unbalanced annotation distribution, and noisy labels. I developed a large-scale item categorization system for Daum Shopping based on a deep network, from the operation tool to the categorization API.

Internship

  • Research internship (Naver Labs)

    Aug. 2015 - Dec. 2015

    • During the internship, I implemented batch normalization (BN) to AlexNet, Inception v2 and VGG on ImageNet using Caffe. I also researched batch normalization for sequential models, e.g., RNN using Lua Torch.
  • Software engineer (IUM-SOCIUS)

    Jun. 2012 - Jan. 2013

    • I worked as web developer at IUM-SOCIUS. During the internship, I developed and maintained internal batch services (JAVA spring batch), internal statistics service (Python Flask, MongoDB), internal admin tools (Python Django, MySQL), and main service systems (JAVA spring, Ruby on Rails, MariaDB).
