RollingLDA: An Update Algorithm of Latent Dirichlet Allocation to Construct Consistent Time Series from Textual Data (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Existing methods for generating time series on textual data are not efficient . |
| Approach: | They propose a rolling version of the Latent Dirichlet Allocation, called RollingLDA . they compute similarity of sequentially obtained topic and word distributions over consecutive time periods . |
| Outcome: | The proposed method is based on the popular model Latent Dirichlet Allocation . it is able to build time series consistent with previous states of the model . |
