摘要:

PHOTONAI是一个高级Python API,旨在简化和加速机器学习模型开发。它作为一个统一的框架,允许用户轻松地访问和组合算法从不同的工具箱到自定义算法序列。它专门设计用于支持迭代模型开发过程,并自动执行重复训练、超参数优化和评估任务。重要的是,该工作流程确保了无偏的性能估计,同时仍然允许用户完全自定义机器学习分析。PHOTONAI扩展了现有的解决方案,采用了一种新的管道实现,支持更复杂的数据流、功能组合和算法选择。使用PHOTONAI Explorer可以方便地可视化分析和结果,并且可以以标准化格式共享预测模型,以进行进一步的外部验证或应用。不断增长的附加生态系统使研究人员能够为社区提供数据模式特定的算法,并增强生命科学领域的机器学习。它的实际效用是证明了一个典型的医疗机器学习问题,实现了国家的最先进的解决方案,在几行代码。源代码在Github上公开,而示例和文档可以在www.photon-ai.com上找到。

英文摘要:

PHOTONAI is a high-level Python API designed to simplify and accelerate machine learning model development. It functions as a unifying framework allowing the user to easily access and combine algorithms from different toolboxes into custom algorithm sequences. It is especially designed to support the iterative model development process and automates the repetitive training, hyperparameter optimization and evaluation tasks. Importantly, the workflow ensures unbiased performance estimates while still allowing the user to fully customize the machine learning analysis. PHOTONAI extends existing solutions with a novel pipeline implementation supporting more complex data streams, feature combinations, and algorithm selection. Metrics and results can be conveniently visualized using the PHOTONAI Explorer and predictive models are shareable in a standardized format for further external validation or application. A growing add-on ecosystem allows researchers to offer data modality specific algorithms to the community and enhance machine learning in the areas of the life sciences. Its practical utility is demonstrated on an exemplary medical machine learning problem, achieving a state-of-the-art solution in few lines of code. Source code is publicly available on Github, while examples and documentation can be found at www.photon-ai.com.
