MatBERT synthesis classifier

A synthesis paragraph classifier built by fine-tuning MatBERT. Built by the text-mining team at CEDER group.

Usage

from synthesis_classifier import get_model, get_tokenizer, run_batch

model = get_model()
tokenizer = get_tokenizer()

paragraphs = [...]

for batch in batches:
    result = run_batch(batch, model, tokenizer)
    print(result)

# Output:
# [{
