Welcome to the world of conversational AI where the Fine-tuned LongT5 model takes center stage! In this article, we will walk you through the process of utilizing this model for Conversational Question Answering (QA). We will also touch on troubleshooting tips to ensure seamless implementation. Let’s dive in!

Understanding the Fine-tuned LongT5 Model

The Fine-tuned LongT5 model is a specialized version of the long-t5-tglobal-base, meticulously tuned for the Conversational QA task. It has been trained on pivotal datasets including:

• SQuADv2
• CoQA
• Your own custom dataset called TryoCoQA

In essence, think of the Fine-tuned LongT5 model as a linguist who’s learned and perfected conversations from an extensive library of QA interactions, making it proficient in understanding and generating responses in a conversational context.

Getting Started with the Model

To work with the Fine-tuned LongT5 for Conversational QA, follow these steps:

• First, ensure you have installed the necessary libraries, especially transformers and torch.
• Load the pre-trained model into your environment.

from transformers import LongT5Tokenizer, LongT5ForConditionalGeneration

tokenizer = LongT5Tokenizer.from_pretrained("google/long-t5-tglobal-base")
model = LongT5ForConditionalGeneration.from_pretrained("google/long-t5-tglobal-base")

• Fine-tune the model using your preferred datasets.
• Once the model is fine-tuned, you can export it to ONNX format for optimized inference. Download the model export at tryolabs/long-t5-tglobal-base-blogpost-cqa-onnx.
• Finally, implement the model in your applications and test its conversational prowess!

Results to Expect

What can you achieve with your Fine-tuned LongT5 model?

• After fine-tuning for 3 epochs on SQuADv2 and CoQA combined, expect a noteworthy F1 score of 74.29 on the test set.
• With 166 epochs on the TryoCoQA dataset, you could see an F1 score of 54.77.

Troubleshooting Tips

While using the Fine-tuned LongT5 model, you may encounter some hiccups. Here are a few troubleshooting ideas:

• Model Loading Issues: Ensure that all necessary libraries are properly installed and updated.
• Performance Expectations: The performance might vary based on the dataset and the number of epochs you have trained on. Experiment with these parameters for the best results.
• Saving Model State: If your model doesn’t seem to retain learning after sessions, ensure you correctly save and load your model’s state dict.
