fastChrF

Fast computation of sentence-level ChrF, motivated by Minimum Bayes Risk decoding.

ChrF (Popović, 2015) is a string similarity metric based on character overlap.
Minimum Bayes Risk (MBR) decoding is a strategy for generating text from a language model that requires many pairwise comparisons of strings.

In addition to the standard ChrF metric, we provide a streamlined variant that is faster to compute if there are many hypotheses and references, which is especially useful for MBR decoding. The streamlined variant is described in the research paper "Linear-time Minimum Bayes Risk Decoding with Reference Aggregation".

Installation

pip install fastchrf

Usage

Parallelized computation of pairwise ChrF scores

Use the fastchrf.pairwise_chrf function to compute the ChrF score between each hypothesis and each reference in a set of hypotheses and references:

import numpy as np
from fastchrf import pairwise_chrf

hypotheses = ["The cat sat on the mat.", "The cat sat on the hat."]
references = ["The cat sat on the mat.", "The fat cat sat on the mat.", "A cat sat on a mat."]
pairwise_scores = pairwise_chrf([hypotheses], [references])

print(np.array(pairwise_scores))
# [[[100.          74.63190449  55.77074554]
#   [ 79.65373543  57.15287549  50.72182797]]]

pairwise_chrf works with a batch dimension, so pass a list of lists of hypotheses and a list of lists of references.
For each row in the batch, the function calculates the segment-level ChrF score between each hypothesis and each reference.
The output has shape (batch_size, num_hypotheses, num_references).

fastchrf.pairwise_chrf compares each hypothesis to each reference. This is slow when the number of hypotheses and references is large, as is the case in MBR decoding.

Faster alternative: A streamlined ChrF variant for MBR

fastchrf.aggregate_chrf computes a streamlined variant of ChrF that is faster to compute:

import numpy as np
from fastchrf import aggregate_chrf

hypotheses = ["The cat sat on the mat.", "The cat sat on the hat."]
references = ["The cat sat on the mat.", "The fat cat sat on the mat.", "A cat sat on a mat."]
aggregate_scores = aggregate_chrf([hypotheses], [references])

print(np.array(aggregate_scores))
# [[78.56389721 63.37194047]]

aggregate_chrf does not output individual scores for each reference. Instead, it outputs an aggregate score across references.
The output has shape (batch_size, num_hypotheses).
The aggregate score is not equal to the average of the individual scores, nor is it equal to standard multi-reference ChrF. See our paper for a formal description.

[!NOTE] The ACL 2023 Policy on AI Writing Assistance requires authors to disclose the use of AI code assistants. For this package, we used GitHub Copilot and GPT-4 to port Python code to Rust. We then used unit tests to ensure that the generated functions are equivalent to the original Python code. In addition, we adapted the original sacreBLEU tests to make sure that the output of the generated functions matches the output of the sacreBLEU implementation of ChrF.

[!CAUTION] fastChrF is not intended to be used as an evaluation metric. For evaluating NLG systems with the ChrF metric, use the implementation provided by sacreBLEU instead.
