中文简介:
连续时间随机动力模型的推理是一个具有挑战性的问题。为了补充现有的基于采样的方法,变分方法最近被开发出来解决这个问题。我们的方法通过离散化来解决变分连续时间推理问题,本质上将其简化为离散时间问题。我们的框架使模型的学习和推理更加容易。其他扩展,如异方差模型,在这个框架中也相对容易考虑。
课程简介: Inference in continuous-time stochastic dynamical models is a challenging problem. To complement existing sampling-based methods, variational methods have recently been developed for this problem. Our approach solves the variational continuous-time inference problem by discretisation that essentially reduces it to a discrete-time problem. Our framework makes learning the model in addition to inference easy. Other extensions such as heteroscedastic models are also relatively easy to consider within this framework.
关 键 词: 连续时间; 非线性状态; 空间模型; 变分推理
