mtslearn: Machine Learning in Python for Medical Time Series
🤖 AI Summary
This work addresses the challenges posed by the high heterogeneity and inconsistent formatting of clinical time-series data, as well as the steep learning curves and fragmented workflows of existing AI tools that hinder clinical adoption. To overcome these barriers, we propose an end-to-end integrated toolkit tailored for medical time-series data. The toolkit unifies diverse input formats—including wide, long, and flat tables—through a standardized data interface and supports a complete pipeline encompassing data ingestion, alignment, feature engineering, model training, and visualization, with extensibility for custom algorithms. Built on a modular architecture and intuitive API, it enables complex data processing tasks to be accomplished in just a few lines of code, substantially lowering the entry barrier for clinicians without programming expertise. Implemented in Python, the toolkit significantly enhances preprocessing efficiency and accelerates both hypothesis exploration and the clinical translation of AI technologies.
📝 Abstract
Medical time-series data captures the dynamic progression of patient conditions, playing a vital role in modern clinical decision support systems. However, real-world clinical data is highly heterogeneous and inconsistently formatted. Furthermore, existing machine learning tools often have steep learning curves and fragmented workflows. Consequently, a significant gap remains between cutting-edge AI technologies and clinical application. To address this, we introduce mtslearn, an end-to-end integrated toolkit specifically designed for medical time-series data. First, the framework provides a unified data interface that automates the parsing and alignment of wide, long, and flat data formats. This design significantly reduces data cleaning overhead. Building on this, mtslearn provides a complete pipeline from data reading and feature engineering to model training and result visualization. Furthermore, it offers flexible interfaces for custom algorithms. Through a modular design, mtslearn simplifies complex data engineering tasks into a few lines of code. This significantly lowers the barrier to entry for clinicians with limited programming experience, empowering them to focus more on exploring medical hypotheses and accelerating the translation of advanced algorithms into real-world clinical practice. mtslearn is publicly available at https://github.com/PKUDigitalHealth/mtslearn.
