myna's Introduction

Myna

Android 平台情景感知框架

GitHub license

Myna 项目中包含一个测试 Demo 工程:demo-myna, 将该工程和 Myna 项目本身导入到 Android Studio 中,就可以开始调试了。

Myna 提供了两套接口:

  • 面向开发者的接口:开发者只需要简单的接口调用,就能在应用程序中获取实时识别的用户行为状态。
  • 面向数据科学家的接口:数据科学家可以很方便地添加新的识别算法,在运行时调整订阅的传感器类型、采样频率和采样时长,而无需关心 Android 系统相关的传感器数据订阅细节。

目前 Myna 可以识别下面三种行为类型:

  1. On_Foot
  2. In_Vehicle
  3. Still

Myna 使用随机森林分类算法的一种开源实现--Dice 进行的实时用户行为识别:

Myna中内置了一个已经训练好的模型文件,在运行时加载。模型的 ROC 为:
