PredictionIO:是一个面向开发者和机器学习工程师的开源(Apache v2)机器学习服务器,基于 Apache Spark, Apache HBase 和 Spray 构建。
目录 |
[编辑] 简介
PredictionIO 主要由三部分组成:数据收集和存储、模型训练以及模型部署和服务暴露。
开发者只需要基于它提供的相应接口实现数据处理逻辑、模型算法和预测逻辑,无需在诸如存储数据以及训练模型之类的事情上投入额外精力。在不要求高并发处理的情况下,PredictionIO 能支持不同大小的数据集。可使用 PredictionIO 来为中小企业构建预测类智能服务,或者在构建复杂定制化预测引擎的过程中进行概念验证。
Apache PredictionIO主要依赖以下项目:
