I enjoy building and testing cool things! These are some of my featured independent/collaborative projects below.

Vision-based Localization and Path Planning TurtleBot System
Huaze Liu, Jessica Liu
ENGR205 -- State Estimation Final Project
[Report] / [Code]

Developed a dual-robot system for autonomous emergency response, where an "explorer" robot uses vision-based detection and an EKF/UKF to locate targets and a "rescuer" robot uses the A* algorithm to navigate to them. The framework is validated in the Webots simulator.

Transfer Learning of DETR for Traffic Object Detection
Huaze Liu, Qingyang Zeng
CSCI153 -- Computer Vision Final Project
[Report] / [Code]

Fine-tuned DETR and RT-DETR models for traffic object detection task using KITTI object detection dataset, achieving 71.1% mAP 50 with 18.1ms latency.

A Multi-Objective Acquisition Function of Bayesian Optimization
Huaze Liu, Zihao Gao, Qingyang Zeng, Ruijie Li
CSCI158 -- Machine Learning Final Project
[Report]

We developed a Scalarized Upper Confidence Bound function for Bayesian Optimization in hyperparameter tuning. It was tested by benchmarking on SVM and CNN models, reducing latency by 8% at equivalent accuracy compared to standard methods.
