The posting

1. 构建时序研究数据集:整理项目中的文本信号、事件记录、实体关系及相关数值数据,完成时间对齐、缺失处理、特征构建和质量检查,明确不同信息的实际可获得时间。 2. 复现预测模型与基线方法:阅读时序分析、事件预测等方向论文,复现统计学习、机器学习或深度学习方法,建立可重复运行的预测实验流程。 3. 探索多源信息融合方法:研究文本信息、事件信号与数值时序数据的融合方式,参与时序表示学习、多时间尺度建模及预测不确定性估计等算法研究。 4. 开展严格实验评估:按照时间顺序组织训练与测试,进行滚动验证、消融实验和跨时期稳健性分析,关注未来信息泄漏、过拟合及数据分布变化等问题。 5. 验证预测模型应用价值:将有效方法接入事件感知与预测系统,评估模型对事件追踪和判断更新的支持能力;在投资相关场景中,参与信号有效性分析与策略回测,考虑信息延迟、交易成本等实际约束。

1. 招募对象:本科生、硕士研究生。 2. 计算机、人工智能、数学、统计、运筹学、计量经济学等相关专业背景优先。 3. 具备概率统计、线性代数和机器学习基础,了解时间序列分析、优化方法或计量经济学者优先。 4. 具备 Python 数据处理与建模能力,能够完成数据清洗、模型训练、实验分析和结果可视化;熟悉至少一种机器学习或深度学习框架。 5. 有时序预测、事件建模、异常检测、算法竞赛、论文复现或量化研究经历者优先,不要求具备金融从业或交易经验。 6. 能够阅读英文论文和技术资料,重视实验设计、数据质量和误差分析,而不仅关注单次实验结果。 7. 具备良好的实验记录和科研习惯,能够稳定投入项目研发并参与阶段性汇报。 8. 不要求已有正式科研经历或论文发表,更关注数学基础、实验能力和研究兴趣。 9. 实习安排:线下科研实习;周期6个月以上;每周投入30小时以上。

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
