这个项目使用基于BERT的多任务学习框架，同时解决学生数学解题过程中的三个关键任务： 1. **答案正确性分类**：判断学生答案是否正确（二分类） 2. **误解类型检测**：识别学生是否在解题中存在误解（二分类） 3. **具体误解分类**：识别学生解题中具体存在的误解类型（多分类） 该系统通过联合学习三个相关任务，实现了知识迁移和模型参数共享，显著提升了各个任务的�

Stars, PRs, issues and forks are under-captured in the later part of this window. GH Archive progressively stopped capturing non-push events during 2026 — −95% or worse by the end of the window. Every series here except Pushes fades for that reason, so a decline above reflects the archive, not this repository. Pushes stay reliable throughout, so read them, and the contributor counts derived from them, as the real signal. Data health has the measurements.
Top contributors
Pushes, PRs, issues, reviews and comments — stars and forks excluded, so this is contribution rather than popularity
Nobody pushed, opened or commented here in the loaded window — this repo's activity is stars and forks only.
Recent activity
Latest issues, pull requests and releases
No issue or PR events — this repo's activity is pushes only.
Totals cover only the window loaded into ClickHouse and count events, not GitHub's lifetime totals — 0 stars here means stars gained during the window, not the repo's star count.
