Abstract
Learning language representations is a key component in many natural language processing tasks, and their usefulness is most often challenged by specialized target domains and vocabulary. We have witnessed several neural causal language models (CLM) that learn contextual representations such as ELMo [8]. More recently, the Transformer architecture [10] has tremendously improved language representation learning, giving birth to new architectures such as BERT [4], a masked language model, pushing the state-of-the-art of natural language understanding to an unprecedented level of performance on standard benchmarks. Moreover, it has been found that Transformer-based CLM, such as GPT [9], are excellent feature extractors as well as being impressive text generators. BART [7], an architecture combining the backbone of both BERT and GTP proved to be particularly effective at generating text while being competitive in comprehension tasks. BARThez, the French version of BART, was recently introduced as a pre-trained model on a very large monolingual French corpus [6]. In this paper, we introduce CriminelBART, a fine-tuned version of BARThez specialized for criminal law using a French Canadian corpus of legal judgments, and we evaluate its performance on different tasks.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
