WebThe results indicated that the proposed model obtained the highest mIoU and F1-score in both datasets, demonstrating that the ResU-Net with a transformer embedded can be used as a robust landslide detection method and thus realize the generation of accurate regional landslide inventory and emergency rescue. WebDynamic Embedded Topic Model (D-ETM) [10] takes the Embedded Topic Model (ETM) [11], and adds a time-varying aspect. D-ETM runs ETM for each time period in the data set, passing parameters into the next time period like in D-LDA. The graph-based Dynamic Topic Model (GDTM) [12] is a scalable dynamic topic model for social media. WebApr 7, 2024 · It is shown that using a topic model that models concepts on a space of word embeddings can lead to significant increases in concept detection performance, as well as enable the target concept to be expressed in more flexible ways using word vectors. 2 PDF View 2 excerpts kirby with long legs
