AI system

System

Groningen AI-based writer-identification pipeline (neural-network binarisation with textural and allographic feature analysis)

Model

BiNet.

Release

Exact release not established.

Application developer

University of Groningen (Dhali, Schomaker, Popović)

Role

The software analyzed handwriting features and separated the columns into two groups.

Configuration

Not assessed

Inputs and outputs

Not assessed

Autonomy

Not assessed

Workflow

High-resolution digital images of all 54 columns. Neural-network separation of ink from background. Textural and allographic features compared statistically across column groups.

Human oversight

Not assessed

Relation to AI

The AI analysis produced the statistical separation of the columns into two groups. The scribal interpretation and the conclusion that two scribes were responsible were made by the authors. The method's developers and the finding's authors are the same team. The only non-developer cited source is the University of Groningen's statement as carried by phys.org. Independent coverage (Smithsonian, CNN) is not among the sources.
