A Latent Topic Model with Markovian Transition for Process Data
Haochen Xu, Guanhua Fang, Zhiliang Ying
We propose a latent topic model with a Markovian transition for process data, which consist of time-stamped events recorded in a log file. Such data are becoming more widely availa…
Latent Theme Dictionary Model for Finding Co-occurrent Patterns in Process Data
Guanhua Fang, Zhiliang Ying
Process data, temporally ordered categorical observations, are of recent interest due to its increasing abundance and the desire to extract useful information. A process is a colle…
An Exploratory Analysis of the Latent Structure of Process Data via Action Sequence Autoencoder
Xueying Tang, Zhi Wang, Jingchen Liu +1
Computer simulations have become a popular tool of assessing complex skills such as problem-solving skills. Log files of computer-based items record the entire human-computer inter…
Latent Feature Extraction for Process Data via Multidimensional Scaling
Xueying Tang, Zhi Wang, Qiwei He +2
Computer-based interactive items have become prevalent in recent educational assessments. In such items, the entire human-computer interactive process is recorded in a log file and…
