Usage

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

tok = AutoTokenizer.from_pretrained("CyberKunju/finehance-categorizer-minilm")
model = AutoModelForSequenceClassification.from_pretrained("CyberKunju/finehance-categorizer-minilm")
model.eval()

desc = "UBER *EATS HELP.UBER.COM"
inputs = tok(desc, return_tensors="pt", truncation=True, max_length=64)
with torch.no_grad():
    logits = model(**inputs).logits
pred_id = logits.argmax(-1).item()
print(model.config.id2label[pred_id])

Intended as the MiniLM arm of a 3-way probability-blend ensemble (TF-IDF LR ⊕ LightGBM on MiniLM embeddings ⊕ this classifier) inside the Finehance Tier 2 categorizer.
