How to Utilize the Splinter Model for Few-Shot Question Answering

August 20, 2021

In this article, we will explore the Splinter base model, a pre-trained model that excels in few-shot question answering. Whether you’re a researcher, a developer, or simply an AI enthusiast, you’ll find helpful guidance in utilizing this model effectively.

Understanding the Splinter Model

The Splinter model is designed to aid in few-shot question answering (QA) by employing a self-supervised learning technique. Imagine you have a bookshelf filled with a myriad of books (our training data from Wikipedia and BookCorpus). Instead of having a librarian label every book, the Splinter model learns to identify essential ideas from the text automatically. It uses a technique called Recurring Span Selection (RSS) to pinpoint sections of text that can be helpful in answering questions.

To illustrate, think of it as a treasure hunt where you’re trying to find repeated phrases or sentences throughout your favorite novels. The model collects these “treasures” (or n-grams), and when it encounters a question, it replaces parts of the text with a [QUESTION] token, indicating what needs to be answered. Like a keen detective, it works to uncover the correct responses by analyzing the context surrounding these tokens.

How to Get Started with Splinter

Install Required Libraries: Ensure that you have Python and necessary machine learning libraries installed in your development environment.
Load the Splinter Model: Use the model from its original repository or access it on Hugging Face.
Preprocess Your Data: Make sure to format your questions and context appropriately according to the model’s requirements.
Make Predictions: Feed the model with data and retrieve answers using its predict function.

Model Limitations

While powerful, it’s important to note that the Splinter model has its limitations. It does not include pretrained weights for the Question-Aware Span Selection (QASS) layer, leading to random initializations upon loading. For those seeking the model with these weights, you can refer to the tausplinter-base-qass.

Troubleshooting Common Issues

Model Not Loading: Make sure you have the correct dependencies installed and are accessing the repository URLs properly.
Inconsistent Answers: Double-check your input formatting as the model relies on well-structured questions and contexts for accuracy.
Performance Issues: Ensure you are working with an appropriate environment; a TPU or GPU is recommended for optimal performance.
Random Initialization Problems: If using the Splinter model without the QASS layer’s weights, experiment with fine-tuning or additional training on your dataset.
