Processing Documents: Jev vs OSS Models
This video compares several model architectures (Jev, Quen, Leia, Jeff) for automating decision-making and classification tasks within document processing pipelines. The core finding is that the open decoder model, Quen, performs remarkably close to the generalized classifier, Jev, across various tasks (language detection, document classification, document routing). The approach demonstrates that robust classification can be achieved without requiring pre-training on specific labels, making it highly valuable for building flexible, automated document pipelines.
Key takeaways
-
Quen's Performance in Classification
The Quen decoder model, which is a standard Language Model (LM) and not specifically trained for classification, showed accuracy very close to Jev in tasks like language detection and document routing, suggesting its utility for general document understanding.

Model Architecture Comparison
7:16
Jev is a generalized classifier trained with reinforcement learning, optimized for confidence scoring. Quen is a decoder LM. Leia and Jeff are encoder models (Leia predicts a mask token; Jeff is good for entity/relation extraction). While encoders are smaller and easier to fine-tune, they were less accurate than the decoders in this demonstration.

Document Processing Tasks Covered
The models were tested on five key document pipeline tasks: Language Detection (using Lingua as baseline), Orientation Detection (using Tesseract as baseline), Document Classification, Document Splitting, and Document Routing/Triage.
