Finance Document Classifier

This repository contains a classifier for determining whether a document is finance-related.

Model Overview

• A regression-based classifier with two classes: financial (1) and non-financial (0).
• Uses Snowflake/snowflake-arctic-embed-m as the embedding model with a classification head. During the training, we train the model in a regression way.
• We used Qwen/Qwen2.5-72B-Instruct to annotate 110k CulturaX documents with a note between 0 and 5, for the training, scores between [0,2] are converted to 0, [3,5] to 1. Then trained on 108k and test on 2k.

How to Use

from transformers import AutoTokenizer, AutoModelForSequenceClassification

# Load tokenizer and model
tokenizer = AutoTokenizer.from_pretrained("LinguaCustodia/ClassiFin")
model = AutoModelForSequenceClassification.from_pretrained("LinguaCustodia/ClassiFin")

# Example text
text = "This is a test sentence."

# Tokenize input
inputs = tokenizer(text, return_tensors="pt", padding="longest", truncation=True)

# Get model outputs
outputs = model(**inputs)
logits = outputs.logits.float().detach().cpu().numpy()
logits = logits.ravel().tolist()

# Convert logits to class labels
int_scores = [int(round(max(0, min(logit, 1)))) for logit in logits]  # 0 for non-financial, 1 for financial

Model Performance

• Evaluated on the test set of 2000 samples.
