BERTJudge-Formatted-QCR

BERT-as-a-Judge is a family of encoder-based models designed for efficient, reference-based evaluation of LLM outputs. Moving beyond rigid lexical extraction and matching, these models evaluate semantic correctness, accommodating variations in phrasing and formatting while using only a fraction of the computational resources required by LLM-as-a-Judge approaches.

Model Summary

Paper: BERT-as-a-Judge: A Robust Alternative to Lexical Methods for Efficient Reference-Based LLM Evaluation
Code: https://github.com/artefactory/BERT-as-a-Judge
Model Type: Encoder-based Judge (EuroBERT-210m backbone)
Language: English

Intended Use

BERTJudge models are designed as sequence classifiers that output a sigmoid score reflecting answer correctness. For inference, we suggest using the BERT-as-a-Judge package.

Installation

zsh

git clone https://github.com/artefactory/BERT-as-a-Judge.git
cd BERT-as-a-Judge
pip install -e .

Usage

Example:

python

from bert_judge.judges import BERTJudge

# 1) Initialize the judge
judge = BERTJudge(
    model_path="artefactory/BERTJudge",
    trust_remote_code=True,
    dtype="bfloat16",
)

# 2) Define one question, one reference, and several candidate answers
question = "What is the capital of France?"
reference = "Paris"
candidates = [
    "Paris.",
    "The capital of France is Paris.",
    "I'm hesitating between Paris and London. I would say Paris.",
    "London.",
    "The capital of France is London.",
    "I'm hesitating between Paris and London. I would say London.",
]

# 3) Predict scores (one score per candidate)
scores = judge.predict(
    questions=[question] * len(candidates),
    references=[reference] * len(candidates),
    candidates=candidates,
    batch_size=1,
)

print(scores)

Naming Convention Breakdown

Models follow a standardized naming structure: BERTJudge-<Candidate_Format>-<Input_Structure>-<Additional_Info>.

Candidate Format:
- Free: Trained on unconstrained model generations.
- Formatted: Trained on outputs that adhere to specific structural constraints. For optimized evaluation under the formatted setup, candidate outputs should ideally conclude with "Final answer: <final_answer>" (see the paper for details).
Input Structure:
- QCR: The input sequence consists of [Question, Candidate, Reference].
- CR: The input sequence consists only of [Candidate, Reference].
Additional Info:
- OOD: Indicates evaluation of Out-of-Distribution performance (where specific generative models were withheld during training).
- 100k/200k/500k: Denotes the total training steps (default regime being 1 million).

Note: For optimal evaluation performance, we recommend using BERTJudge-Free-QCR, available as artefactory/BERTJudge.
