AraSeg 2026 · e76 — NoPnx-PA ensemble member

One member of NAMAA's NoPnx-PA system for the Arabic Segmentation Shared Task 2026 (AraSeg, ArabicNLP 2026). Trained on text with Naqta-predicted commas inserted. Requires Naqta at inference (min_p=0.3, comma=','), not only at training time. Decoder weight +0.0727. Entered the lock in the same 2026-08-02 joint gate as e69.

This is not a standalone segmenter. It is one voter inside an ensemble, and it produces uncalibrated per-word boundary probabilities. Used alone it does not reproduce any published score. The system that does is NAMAA-Space/araseg-2026, which holds the combiner weights and thresholds.

Loading

from_pretrained will not work. The file is a bare state_dict; the architecture is built from the experiment's config YAML and the base model, then the weights are loaded in:

import torch
from huggingface_hub import hf_hub_download

path = hf_hub_download("NAMAA-Space/araseg-e76-naqta-restore-nopnx-pa-s2", "best_NoPnx_PA.pt")
state = torch.load(path, map_location="cpu")
# build the architecture first -- see ensemble.py / verify_offcluster.py in the repo

The five LoRA members additionally need transformers==5.12.1 to instantiate their base classes. Full pinned stack: requirements-llm.txt in the code repo.
