Detection Of Learning Obstacles via Risk-aware Interaction Signals
Project description
Doloris
中山大学 2025 年《模式识别》课程大作业项目
组员:许睿林、傅小桐
Doloris(Detection Of Learning Obstacles via Risk-aware Interaction Signals)是一款用于基于交互信号分析学习障碍的检测系统。它支持用户友好的命令行界面、可视化面板以及灵活的机器学习模型配置,适用于教育行为数据分析与预测任务。
🔧 安装方式
用户安装(推荐)
使用 pip 一键安装:
pip install doloris
开发者模式安装
若你正在开发或调试本项目,建议使用源码安装:
pip install .
安装完成后可通过下列命令验证版本:
doloris version
🚀 快速开始
启动可视化面板
运行以下命令以启动 Doloris 的交互式面板(默认缓存路径为 .doloris/):
doloris panel --cache-path <缓存目录路径>
可选参数:
--cache-path:指定缓存数据的目录路径(默认.doloris/)--share:是否开启公网访问链接(默认 False)
运行模型算法
Doloris 提供命令行方式运行学习障碍检测算法,算法运行可视化结果保存在缓存路径下的 algorithm_output 文件夹:
doloris algorithm --cache-path <缓存目录路径> \
--label-type <binary|multiclass> \
--feature-cols <特征列1,特征列2,...> \
--model-name <模型名称>
可用参数说明:
-
--cache-path:指定缓存数据的目录路径(默认.doloris/) -
--label-type:指定标签类型(默认:binary),可选值:binary,multiclass -
--feature-cols:用逗号分隔的特征列名(默认为预设特征) -
--model-name:选择的模型名称,支持如下几种:logistic_regressionrandom_forestknnsvmsgdmlp
示例命令:
doloris algorithm --label-type binary --model-name random_forest
🧠 默认特征说明
默认使用以下交互特征进行建模:
- age_band
- highest_education
- imd_band
- num_of_prev_attempts
- studied_credits
- total_n_days
- avg_total_sum_clicks
- n_days_oucontent
- avg_sum_clicks_quiz
- avg_sum_clicks_forumng
- avg_sum_clicks_homepage
你也可以通过 --feature-cols 参数自定义特征列表。
