This model uses a custom classification head (mean pooling over a backbone without a native sequence-classification class), so loading requires trust_remote_code=True. vLLM serving requires a standard architecture.

Evaluation

Metric	Value
f1_micro @ 0.5	0.5898
f1_macro @ 0.5	0.3989
f1_micro @ tuned	0.6238
f1_macro @ tuned	0.5177

Per-label decision thresholds tuned on the eval split are stored in config.classifier_thresholds.

Choosing an operating point: the stored thresholds maximise per-label F1. For precision-first use (e.g. auto-applying labels), act only on predictions well above their threshold — sigmoid probabilities are a usable confidence signal, and filtering to high-confidence predictions trades coverage for precision. Route the rest to review.

Usage

import torch
from transformers import AutoModelForSequenceClassification, AutoTokenizer

model = AutoModelForSequenceClassification.from_pretrained("davanstrien/dataset-schema-task-classifier", trust_remote_code=True)
tokenizer = AutoTokenizer.from_pretrained("davanstrien/dataset-schema-task-classifier", trust_remote_code=True)

inputs = tokenizer("your text here", return_tensors="pt", truncation=True)
probs = torch.sigmoid(model(**inputs).logits)[0]
thresholds = torch.tensor(model.config.classifier_thresholds)  # tuned on validation
labels = [model.config.id2label[i] for i in (probs >= thresholds).nonzero().flatten().tolist()]
print(labels)
