Qlib | Open Source AI Quantitative Investment Platform Unleashes New Potential for Quantitative Investing

I. Software overview

Qlib is an open source, AI-oriented quantitative investment platform from Microsoft. It aims to realize the potential, power research and create value in quantitative investment through AI technology, covering the whole process from idea exploration to practical application. The platform supports multiple machine learning modeling paradigms, such as supervised learning, market dynamics modeling, and reinforcement learning, providing powerful research and practice tools for the quantitative investment field.

II. Software features

1. Rich Model SupportThere are many quantitative models based on different frameworks, such as GBDT models based on XGBoost, LightGBM, Catboost, etc., as well as MLP, LSTM, GRU, etc. based on pytorch, so that users can choose the appropriate model for quantitative research according to their needs.
2. Data processing and preparation: Provides functionality for data acquisition, processing and updating. Although official datasets are temporarily disabled due to data security policies, users can use community-contributed data sources. Data can be fetched at different frequencies in a variety of ways, and scripts are provided to check the health status of the data.
3. Automated quantitative research workflowThe "qrun" tool automates the entire quantitative research workflow, including dataset construction, model training, backtesting and evaluation, and generates graphical reports for analysis, making it easy for users to conduct quantitative research quickly.
4. Customized workflow building: To meet the needs of different researchers, a modular interface is provided to allow researchers to build customized quantitative research workflows through code.

III. Software Advantages

1. Diversity of technologies and paradigmsThe company supports a variety of machine learning modeling paradigms that can be adapted to different quantitative investment scenarios and research needs, helping to address key challenges in quantitative research, such as mining signals from complex financial data, adapting to market dynamics, and optimizing trading strategies through reinforcement learning.
2. Strong infrastructure: Provides strong infrastructure support, with data as an important component, and a powerful learning framework designed to support different learning paradigms and models. Components are designed as loosely coupled modules that can be used independently, facilitating the flexible construction of quantitative research environments .
