中文简介: | 我将介绍使用分层概率表示来模拟名为S SEER的系统中人员的活动。我将描述我们如何使用表示在多个时间粒度和抽象级别进行感知,学习和推理。该方法以使用名为分层隐马尔可夫模型(LHMM)的级联隐马尔可夫模型(HMM)为基础,基于来自视频,音频和计算机(键盘和鼠标)交互的实时证据流来诊断用户活动的状态。 |
课程简介: | I will present the use of layered probabilistic representations for modeling the activities of people in a system named S-SEER. I will describe how we use the representation to do sensing, learning and inference at multiple levels of temporal granularity and abstraction. The approach centers on the use of a cascade of Hidden Markov Models (HMMs) named Layered Hidden Markov Models (LHMMs) to diagnose states of a user's activity based on real-time streams of evidence from video, audio and computer (keyboard and mouse) interactions. |
