GPTZero: Examining its Accuracy in Detecting AI Generated Text
Hello there, welcome back to the new video. Today, we'll be talking about GPTZero, which is one of the ways of detecting if a text is written by AI or not.
Over the news, people have been talking a lot about banning GPT, mostly because students have been using it to write assignments and lab tests. In my opinion, this is both a correct and incorrect step to take. During this time, Edwardian found an opportunity to devise an algorithm that detects if a text is generated by AI or not.
You can follow Edward on a sub-stack and if you are interested in checking out the demo for GPTZero, head out to this gptzero.
Comprehensive Description and Analysis
GPTZero essentially works on two principles: calculating perplexity and burstiness. Perplexity is a measure of how likely a given set of words is in a document. Burstiness, on the other hand, is a measure of variability in the complexity of the generated text.
When calculating perplexity, the algorithm considers the likelihood of a document based on the words it has generated in the past. The higher the probability of a generated text, the lower the perplexity and the lower the randomness, indicating it may be written by an AI system.
Burstiness, on the other hand, measures the variability in the complexity of the generated text. Human-generated text tends to have more variation or burstiness compared to AI-generated text.
Expertise Display
GPTZero is based on first-hand knowledge and experience in detecting AI-generated text. The algorithm was developed by Edwardian, who has extensive expertise in the field. The algorithm combines the principles of perplexity and burstiness to classify a given text as either AI-generated or human-written.
While GPTZero is an effective tool for detecting AI-generated text, there are potential ways to fool the system. By adding stochasticity in the generation process, such as increasing the temperature or the value of K in top K sampling, the language model can generate text that is less likely and less predictable. Paraphrasing the text generated by GPT 3 is another tactic that could potentially deceive GPTZero. Additionally, inducing deliberate spelling mistakes or playing around with punctuation can make the text appear more human-like. Writing prompts that generate highly variable length text is another strategy that may fool GPTZero. These are all areas for further experimentation to see how GPTZero reacts to different parameters.
Conclusion
GPTZero has proven to be an effective tool in detecting AI-generated text, using principles of perplexity and burstiness. By analyzing the likelihood and variability of a given text, GPTZero can determine whether it was written by an AI system or a human. However, it is important to note that GPTZero can be fooled under certain conditions, such as introducing stochasticity, paraphrasing, inducing deliberate spelling mistakes, or writing highly variable length text. Further research and experimentation are needed to enhance the accuracy and reliability of GPTZero in detecting AI-generated text.
