• Discovered memory‑efficient auto‑encoders for surface defection detection by evolutionary search, reducing 4× network parameters
• Deployed tiny YOLOv1 (432KB) to MAXIM78000 edge device with Camera input and LCD output.
• Invented a model parallelism for neural architecture search with 1.18× speedup.
• Designed a novel neural architecture search, which improved 3% accuracy under high‑level symmetric label noise.
• Wrote a survey paper of Automated Machine Learning, including automated feature engineering, model selection, hyperparameter tuning, andneural architecture search.

United States

• Built an auto video generation framework to animate image highlights for hundreds of miscellaneous product categories.
• Established the image filter using ResNet to exclude text‑intensive images.
• Designed text and geometric object detectors using Amazon Rekognition and DeepLab to capture headlines, descriptions, and rectangular subjects.
• Utilized Navier‑Stoker inpainter and OpenShot animator to animate captured subjects in product images.
• Accelerated the video generation from 30 minutes (human) to 3 minutes (our framework), getting 10× speedup.

United States

• Proposed adaptive constraint early stopping (ACE) algorithm to find optimal hyperparameters under specific constraints.
• Modeled the expected evaluation cost to tailor the constraint interval to different constraint cost.
• Developed stratum early stopping by using constraint violations.
• Improved feasible AUC of LGBM model from 0.801 to 0.852, getting 6% improvement.
