Where Does Authorship Signal Emerge in Encoder-Based Language Models?
Francis Kulumba, Guillaume Vimont, Laurent Romary +1
Authorship attribution models fine-tuned with the same pretrained encoder, data, and loss can differ four-fold in performance depending only on their scoring mechanism. We use mech…
HALvest-Contrastive: Retrieval-Like Authorship Attribution with Patch-Level Late Interaction
Francis Kulumba, Wissam Antoun, Guillaume Vimont +2
Authorship attribution asks whether two pieces of text share a writer, but topical confound makes the task deceptively easy: two authors covering the same topic may look more alike…
The content correlation of multiple streaming edges
Michel de Rougemont, Guillaume Vimont
We study how to detect clusters in a graph defined by a stream of edges, without storing the entire graph. We extend the approach to dynamic graphs defined by the most recent edges…
Approximate Integration of streaming data
Michel de Rougemont, Guillaume Vimont
We approximate analytic queries on streaming data with a weighted reservoir sampling. For a stream of tuples of a Datawarehouse we show how to approximate some OLAP queries. For a…
