An unsupervised approach for semantic place annotation of trajectories based on the prior probability

no code implementations20 Apr 2022 Junyi Cheng, Xianfeng Zhang, Peng Luo, Jie Huang, Jianfeng Huang

The Bayesian Criterion is specifically employed to decompose the spatiotemporal probability of the candidate place into spatial probability, duration probability, and visiting time probability.

The Linearized Hellinger--Kantorovich Distance

1 code implementation17 Feb 2021 Tianji Cai, Junyi Cheng, Bernhard Schmitzer, Matthew Thorpe

Working with the local linearization and the corresponding embeddings allows for the advantages of the Euclidean setting, such as faster computations and a plethora of data analysis tools, whilst still enjoying approximately the descriptive power of the Hellinger--Kantorovich metric.
