Repository: https://github.com/yophis/decom-renorm-merge

Uses

The model can be loaded as follows:

import torch
from transformers import AutoModelForSequenceClassification, AutoTokenizer

model_id = "yophis/DRM-T5-Base-wikiqa"

# Load the tokenizer
tokenizer = AutoTokenizer.from_pretrained(model_id)
tokenizer.pad_token = tokenizer.eos_token

# Load the model
model = AutoModelForSequenceClassification.from_pretrained(model_id, device_map="auto")
model.config.pad_token_id = model.config.eos_token_id

# Input template
input_text = "Question: {question} Context: {answer}"
