Welcome to the world of Thermostat, a powerful tool that combines Natural Language Processing (NLP) model explanations and analysis tools. It leverages the explainability methods from the Captum library to enhance datasets, providing researchers with a more efficient means to understand machine learning models. This guide will walk you through the installation, usage, and troubleshooting of Thermostat.

Installation

Getting started with Thermostat is as easy as pie! You can install the package using pip by running the following command in your terminal:

bash
pip install thermostat-datasets

Exploring Thermostat on Hugging Face Spaces

Since launching on October 26, 2021, the Spaces edition of Thermostat has made life easier for many users. Feel free to explore it here: Hugging Face Spaces.

Usage

To use the Thermostat for downloading a dataset is straightforward. You only need two simple lines of code:

python
import thermostat
data = thermostat.load('imdb-bert-lig')

Understanding the Data Structure

Imagine you are a librarian organizing a collection of books. Each book (data instance) contains important elements like:

• Attributions: Similar to notes in the margin (the attributions for each token for each data point).
• Identifier (idx): This is like the catalog number that shows the index in your library.
• Token IDs (input_ids): Think of these as the unique barcodes assigned to each book.
• Labels: The genre of the book (such as a label of 0 for negative and 1 for positive).
• Predictions: These are the classifications made by the model, akin to a librarian’s recommendation.

Indexing an Instance

To access a specific instance in your dataset, you can simply index it like so:

python
instance = thermostat.load('imdb-bert-lig')[429]

Visualizing Attributions

Visualization is key to understanding complex data. You can apply a heatmap to visualize the attributions of an instance:

python
instance.render()

Getting Insights with Heatmaps

The explanation attribute gives you a wealth of information in a tuple format:

python
print(instance.explanation)  

Modifying Load Function

You have the flexibility to modify how datasets are loaded with the thermostat.load() function:

python
data = thermostat.load('your_dataset', cache_dir='path_to_cache')

Commonly Used Explainability Methods

Thermostat employs various explainability methods to help researchers. Here’s a glimpse into some of them along with their parameters:

• Layer Gradient x Activation (lgxa): Captum’s LayerGradientXActivation implementation.
• Layer Integrated Gradients (lig): Another popular choice from Captum.
• LIME (lime): Interpretable predictions with a local explanation.

Contributing a Dataset

Think you have a dataset that could benefit the community? It’s easy to add a dataset, just ensure it follows the JSONL format and includes mandatory fields for Thermostat. You can find out more about the necessary metadata in the official documentation.

Troubleshooting

Like any technology, issues may arise. Here are a few troubleshooting ideas:

• Ensure you have the latest version of Thermostat and Captum.
• If you encounter loading issues, check the format of your dataset and metadata.
• For persistent problems, consider looking for community solutions or submitting an issue on the GitHub repository.
