• 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.
