Agreemind English Banking Risk Classifier

Name: en-banking-roberta
Availability: InStock

RoBERTa-base fine-tuned for multi-label clause-level risk detection in English consumer banking contracts.

This model takes a single clause or paragraph from a banking agreement and predicts which risk categories (if any) it contains. It is designed for use in automated contract analysis pipelines where the system must flag potentially unfair or risky terms for consumer review.

Risk Categories

The model classifies clauses into 9 risk categories:

ID	Label	Description	Severity
0	`hidden_fees`	Undisclosed fees, penalty charges, or fee escalation clauses	High
1	`unilateral_rate_change`	Bank can change interest rates without customer consent	High
2	`unilateral_terms_change`	Bank can modify agreement terms unilaterally	Medium
3	`overdraft_or_overlimit_penalty`	Overdraft fees, over-limit charges, penalty APR triggers	High
4	`auto_enrollment`	Automatic enrollment in services requiring opt-out	Medium
5	`data_sharing`	Sharing personal/financial data with third parties	Medium
6	`dispute_limitation`	Restrictions on dispute resolution (arbitration, class action waivers)	High
7	`account_freeze_or_closure`	Bank can freeze, suspend, or close account	Critical
8	`rewards_restriction_or_devaluation`	Changes to rewards programs, point devaluation	Low

A clause with no risk labels is considered fair (all-zero prediction).

Usage

Quick Start

python

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

model_id = "Agreemind/en-banking-roberta"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForSequenceClassification.from_pretrained(model_id)

LABELS = [
    "hidden_fees", "unilateral_rate_change", "unilateral_terms_change",
    "overdraft_or_overlimit_penalty", "auto_enrollment", "data_sharing",
    "dispute_limitation", "account_freeze_or_closure",
    "rewards_restriction_or_devaluation",
]

text = "We may change the interest rate on your account at any time without prior notice."

inputs = tokenizer(text, return_tensors="pt", truncation=True, max_length=256)

with torch.no_grad():
    probs = torch.sigmoid(model(**inputs).logits).squeeze()

# Using recommended global threshold of 0.70
threshold = 0.70
for label, prob in sorted(zip(LABELS, probs), key=lambda x: x[1], reverse=True):
    flag = " ⚠️" if prob >= threshold else ""
    print(f"  {prob:.3f}  {label}{flag}")

With Pipeline API

python

from transformers import pipeline

pipe = pipeline(
    "text-classification",
    model="Agreemind/en-banking-roberta",
    top_k=None,
    function_to_apply="sigmoid",
)

result = pipe("The bank may close your account at any time for any reason.")
# Filter with threshold
risky = [r for r in result[0] if r["score"] >= 0.70]
print(risky)

Recommended Thresholds

For production use, we recommend the global threshold of 0.70 which was tuned on the validation set and consistently outperformed both default 0.5 and per-label thresholds across 5-fold CV.

Optimized per-label thresholds are included in thresholds.json in this repository for advanced use cases.

Early stopping	patience=3 on validation micro-F1
Imbalance handling	BCEWithLogitsLoss with pos_weight computed from training data
Data split	70% train / 15% dev / 15% test (contract-level, seed=42)

Training Data

88 contracts from 17+ US banks including Chase, Bank of America, Wells Fargo, Citibank, US Bank, Capital One, Ally Bank, Truist, TD Bank, Regions, Citizens, HSBC USA, Santander, and others.

Contract types: credit card agreements, prepaid card agreements, deposit account agreements, online banking service agreements, HELOC disclosures, and treasury management agreements.

Limitations

Rare label weakness: auto_enrollment (141 examples) and rewards_restriction_or_devaluation (32 examples) have limited training data and show higher variance
US-centric: Trained exclusively on US banking contracts; may not generalize well to UK, EU, or other jurisdictions
English only: Does not support other languages
Clause-level only: Expects pre-segmented clauses/paragraphs, not full documents
