WIKITEXT Calibration Set for Membership Inference Attacks

This dataset contains a calibration set for training membership inference attack (MIA) classifiers.

Dataset Information

• Total Samples: 50
• Members: 25 (sampled from training data)
• Non-members: 25 (sampled from unseen test split)
• Balance: 50.0% members / 50.0% non-members

Data Sources

Members (label=1)

• Source: 10K training data (excluding eval set)
• Dataset: mia-llm/wikitext-raw-MIA (10K training samples)
• Filtering: Excluded samples that appear in evaluation set

Non-members (label=0)

• Source: Unseen test split
• Original Dataset:
  • AG News: fancyzhx/ag_news (test split)
  • XSum: EdinburghNLP/xsum (test split)
  • WikiText: Salesforce/wikitext wikitext-2-raw-v1 (test split)

Usage

Load Dataset

from datasets import load_dataset

# Load calibration set
dataset = load_dataset("h0ssn/wikitext-calibration-50-mia")

# Access data
calibration_data = dataset['train']

print(f"Total samples: {len(calibration_data)}")
print(f"First sample: {calibration_data[0]}")

Train MIA Classifier

from sklearn.linear_model import LogisticRegression
from sklearn.preprocessing import StandardScaler
import numpy as np

# Load calibration set
calibration_data = load_dataset("h0ssn/wikitext-calibration-50-mia")['train']

# Extract features (example: using loss and gradient)
# You need to compute these features using your target and reference models
features = extract_features(calibration_data['text'])  # Your feature extraction
labels = calibration_data['label']

# Train classifier
scaler = StandardScaler()
features_normalized = scaler.fit_transform(features)

classifier = LogisticRegression(max_iter=1000, random_state=42)
classifier.fit(features_normalized, labels)

# Now use this classifier to predict membership on unknown samples

Data Fields

• text (string): The text content
• label (int): 1 for members, 0 for non-members
• source (string): Origin of the sample ('10k_train' or 'unseen')

Verification

✅ No overlap between members and non-members: All samples have been verified to ensure no duplicates exist between the member and non-member sets.
