jmedroberta-base-manbyo-wordpiece

jmedroberta-base-manbyo-wordpiece is a Japanese RoBERTa-based model optimized for medical text understanding. It has been fine-tuned on CT-RATE-JPN, a large-scale dataset of Japanese chest CT reports, for multi-label classification of 18 common thoracic CT findings.

The model leverages the medical-domain vocabulary coverage of JMedRoBERTa and achieves strong and stable performance on Japanese radiology reports.

Model Overview

Base model: alabnii/jmedroberta-base-manbyo-wordpiece
Task: Multi-label classification (18 abnormal findings)
Training data: CT-RATE-JPN (Japanese translations of CT-RATE reports)
Input: Japanese radiology reports
Output: Probabilities (0–1) for each finding

Usage

python

from transformers import AutoModelForSequenceClassification, AutoTokenizer
import torch

model_name = "alabnii/jmedroberta-base-manbyo-wordpiece"
model = AutoModelForSequenceClassification.from_pretrained(
    model_name,
    num_labels=18,
    problem_type="multi_label_classification"
)
tokenizer = AutoTokenizer.from_pretrained(model_name)

def infer(texts):
    inputs = tokenizer(texts, padding=True, truncation=True, return_tensors="pt")
    with torch.no_grad():
        logits = model(**inputs).logits
    return torch.sigmoid(logits)

texts = ["両肺に淡い浸潤影を認めます。"]
probs = infer(texts)
