Semantic Change Detection With Gaussian Word Embeddings [PDF]

open access: yesIEEE/ACM Transactions on Audio, Speech, and Language Processing, 2021
Diachronic study of the evolution of languages is of importance in natural language processing (NLP). Recent years have witnessed a surge of computational approaches for the detection and characterization of lexical semantic change (LSC) due to the availability of diachronic corpora and advancing word representation techniques.

Scalable and Interpretable Semantic Change Detection [PDF]

open access: yesProceedings of the 2021 Conference of the North American Chapter of the Association for Computational Linguistics: Human Language Technologies, 2021
Several cluster-based methods for semantic change detection with contextual embeddings emerged recently. They allow a fine-grained analysis of word use change by aggregating embeddings into clusters that reflect the different usages of the word. However, these methods are unscalable in terms of memory consumption and computation time.

Beyond Classifiers: Remote Sensing Change Detection with Metric Learning

open access: yesRemote Sensing, 2022
For change detection in remote sensing images, supervised learning always relies on bi-temporal images as inputs and 2-class/multi-class classifiers as outputs. On the other hand, change detection can be viewed as a metric learning problem, i.e., changed
