RPFNet: Attack-Agnostic Tabular Data Poisoning Detection via Meta-Learned Relational Fingerprints

Status: Beta - APIs may change and detection thresholds are still being refined. Results should not be considered production-stable.

RPFNet is a Python library for detecting data poisoning attacks in tabular datasets. It supports batch analysis, streaming detection, and clean dataset export.

---

Installation

pip install rpfnet
pip install ucimlrepo  # only needed for UCI datasets

---

Quick Start

from RPFNet import api

# UCI dataset (by ID)
report = api.analyze('uci', 73)
print(f"Flagged: {report['n_flagged']} / {report['n_rows']}  ({report['pct_flagged']}%)")

# Local CSV
report = api.analyze('csv', 'dataset.csv')

# Remote URL
report = api.analyze('url', 'https://example.com/dataset.csv')
# Google Drive: https://drive.google.com/uc?id=FILE_ID&export=download

Report Keys

Key	Description
n_rows	Total rows analyzed
n_flagged	Rows flagged as potentially poisoned
n_clean	Rows considered clean
pct_flagged	Percentage flagged
estimated_rate	Auto-estimated contamination rate
mode	Scoring mode (rpfnet_hybrid or isolation_forest)
scores	Per-row anomaly scores (0–1)
flags	Per-row binary flags (1 = flagged)
flagged_indices	Row indices of flagged samples
clean_indices	Row indices of clean samples
dataframe	Original data annotated with _poison_score and _poison_flag

---

Export Clean Data

# Returns original DataFrame with poisoned rows removed
clean_df = api.clean('uci', 73)
clean_df = api.clean('csv', 'dataset.csv')
clean_df = api.clean('url', 'https://example.com/dataset.csv')

print(f"Kept {len(clean_df)} clean rows")
clean_df.to_csv('clean_dataset.csv', index=False)

---

Streaming Detection

For real-time or incremental data pipelines, RPFNet supports row-by-row streaming.

import pandas as pd
from RPFNet import api

# Existing dataset — used as baseline
existing = pd.read_csv('dataset.csv')
api.analyze('stream', existing)

# New rows scored against that baseline
for _, row in new_data.iterrows():
    result = api.analyze('stream', row)

    if result['status'] == 'warming_up':
        continue

    if result['poison_flag']:
        print(f"Poisoned row detected! score={result['score']:.4f}")

# Export clean rows from the buffer
clean_df = api.clean('stream')
print(f"Clean rows in buffer: {len(clean_df)}")

# Utilities
api.analyze('stream')       # check buffer status
api.stream_retrain()        # force retrain after concept drift
api.stream_reset()          # wipe buffer and start fresh

Streaming Result Keys

Key	Description
status	warming_up, active
score	Anomaly score for this row
threshold	Current decision threshold
poison_flag	True if row is flagged
n_samples	Rows in current buffer
buffer_pct_flagged	% flagged in buffer window
