Historians don’t have to compress their material as severely. Since history is notoriously a story of conflict, and our sources were interested participants, few people expect historians to represent all aspects of the past with one correctly balanced model. On the contrary, historical inquiry is usually about comparing perspectives. Machine learning is not the only way to do this, but it can help. For instance, researchers can measure differences of perspective by training multiple models on different publication venues or slices of the timeline.[6]
For question three, I believe this highlights the authors transition well because he dicusses the participants reaction the the balanced model which is also talked about throughout the begenning and not only that the perspective of different publications to back up different sources of knowledge throughout the article.
