BiLSTM-CRF Chinese Word Segmentation System

Sat, 01 Feb 2025 00:00:00 +0000

This project implements a Chinese Word Segmentation (CWS) system based on a BiLSTM-CRF architecture, enhanced with several advanced features such as pretrained character embeddings, character-type embeddings, bigram embeddings, multi-corpus training, a customized CRF decoder with illegal transition constraints, loss visualization, and evaluation utilities. The system supports common CWS datasets including MSRA, PKU, and Souhu, and provides a complete workflow from data preprocessing → vocabulary construction → model training → evaluation → inference. Experiments show that the model achieves an F1 score of approximately 0.91 on the MSRA benchmark. The project is modular, extendable, and suitable for both engineering use and academic exploration.

Intelligent Car Based Online Calibration System

Sat, 01 Jun 2024 00:00:00 +0000

Developed an online calibration system using an intelligent car, replacing traditional static object-based calibration. This improved efficiency and reduced labor requirements. Utilized YOLO v9 for computer vision-based calibration and built a basic model of the intelligent car for autonomous movement and calibration.

Modeling Water Quatlity using Regression

Wed, 01 Apr 2020 00:00:00 +0000

Conducted field research in Anji County, Huzhou, collecting water quality data (e.g., temperature, dissolved oxygen, pH) from 7 locations along the upstream of Huangpu River. Performed data analysis using statistical regression models to predict and assess waterquality trends, providing actionable insights for environmental conservation.
