T5 Large for Text Aggregation

Model description

This is a T5 Large fine-tuned for crowdsourced text aggregation tasks. The model takes multiple performers' responses and yields a single aggregated response. This approach was introduced for the first time during VLDB 2021 Crowd Science Challenge and originally implemented at the second-place competitor's GitHub. The paper describing this model was presented at the 2nd Crowd Science Workshop.

How to use

from transformers import AutoModelForSeq2SeqLM, AutoTokenizer, AutoConfig
mname = "toloka/t5-large-for-text-aggregation"
tokenizer = AutoTokenizer.from_pretrained(mname)
model = AutoModelForSeq2SeqLM.from_pretrained(mname)

input = "samplee text | sampl text | sample textt"
input_ids = tokenizer.encode(input, return_tensors="pt")
outputs = model.generate(input_ids)
decoded = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(decoded)  # sample text

Training data

Pretrained weights were taken from the original T5 Large model by Google. For more details on the T5 architecture and training procedure see https://arxiv.org/abs/1910.10683

Model was fine-tuned on train-clean, dev-clean and dev-other parts of the CrowdSpeech dataset that was introduced in our paper.

Training procedure

The model was fine-tuned for eight epochs directly following the HuggingFace summarization training example.
