Building reproducible tools for quantitative research, causal inference, and AI applications.

关注量化研究、因果推断与 AI 应用,把方法做成可以运行、检查和复现的项目。

Selected projects

A Python research pipeline connecting factor evaluation, walk-forward modeling, portfolio construction, transaction costs, and HTML reports. Includes a FastAPI service and a Streamlit dashboard.

Start here: Documentation · Computed sample · Source & tests

The bundled sample data is synthetic; its results demonstrate the workflow and do not establish a tradable edge.

An interactive simulation lab for high-dimensional covariate adjustment, causal estimation, and robust asset allocation.

Explore: Browser demo · Repository

Experiments use simulated data and depend on the chosen data-generating assumptions.

A factor research workflow with point-in-time feature alignment, purged out-of-sample evaluation, portfolio accounting, and browser reports.

The default run uses synthetic data. Complete point-in-time financial statement normalization for real-market experiments is still in progress.
