GLTR

What is GLTR?

Catching Unicorns With GLTR is a tool developed by the MIT-IBM Watson AI lab and HarvardNLP. It is designed to detect automatically generated text using the GPT-2 language model from OpenAI. The tool provides a visual representation of the likelihood that each word in a text was automatically generated, with color-coding indicating probabilities. GLTR aims to help non-experts identify artificial text and promote transparency and reliability in language processing.

The tool uses statistical detection methods based on word probabilities and overlays a color-coded mask over the text to indicate the likelihood that each word was generated by a model. Green represents the top 10 probability, yellow the top 100, red the top 1,000, and purple indicates less likely predictions.

GLTR is an educational tool that offers samples of both real and fake texts, making it valuable for understanding language model behaviors. It is publicly accessible and provides insights into text generation and forensic analysis of model-generated text.

Who created GLTR?

The tool "Catching Unicorns With Gltr" was created by Hendrik Strobelt and Sebastian Gehrmann in collaboration with the MIT-IBM Watson AI lab and HarvardNLP. This innovative tool is designed for forensic analysis to detect automatically generated text, providing a visual footprint to differentiate between human-written and model-generated text.

What is GLTR used for?

• GLTR is used as a forensic tool to detect whether a text has been written by a human or generated by a language model.
• It provides a visual footprint of language model outputs and helps identify artificial text through statistical detection.
• GLTR uses the GPT-2 117M language model to check predictions against actual text and analyze the likelihood of each word being automatically generated.
• The tool presents histograms showing the distribution of word categories probability ratios and prediction entropies, aiding in forensic analysis.
• It serves as an educational resource for understanding language model behaviors by providing samples of both real and fake texts.
• GLTR allows users to input text for analysis and visualize the probabilities of each word being generated by a model through a color-coded overlay.
• This tool can assist non-experts in identifying automatically generated text, promoting transparency and reliability in language processing.
• GLTR can be accessed publicly online with a live demo available for users to try with their own text inputs.
• It is designed to work with the GPT-2 117M language model from OpenAI and provides insights into the generation process of language models.

How to use GLTR?

To use "Catching Unicorns With GLTR," follow these steps:

1. Access the live demo of GLTR at the provided website.
2. Input your desired text for analysis. GLTR will assess the likelihood of each word being automatically generated.
3. The tool overlays a color-coded mask on the text: green for top 10 likely words, yellow for top 100, red for top 1,000, and purple for less likely predictions.
4. Hover over a word to view the top 5 predicted words and their associated probabilities.
5. Explore the three histograms displayed by the tool: one showing word categories, the second illustrating probability ratios, and the last one showing prediction entropies.
6. Analyze the color distribution in the text to identify generated or human-written content. Green and yellow colors may indicate generated text, while purple and red colors suggest human-written text.
7. Utilize GLTR as an educational tool by examining samples of real and fake texts to understand language model behaviors.
8. Experiment with GLTR using your own text through the live demo on the website for further analysis and insights.

GLTR provides statistical detection, visual footprint analysis, access to GPT-2 117M, histograms for aggregate data, and insightful examples for educational purposes. It is a valuable tool for detecting automatically generated text and promoting transparency in language processing.

You can further explore the tool's functionalities and potential applications by experimenting with different types of text inputs and analyzing the color-coded results provided by the GLTR tool.
