Developing algorithms to differentiate between machine-generated texts and human-written texts has garnered substantial attention in recent years.
In the online scenario, the ability to quickly and accurately determine if a source is an LLM (large language model) is crucial to prevent the spread of misinformation and misuse of LLMs.
To address the problem of online detection, an algorithm based on sequential hypothesis testing by betting has been developed.
Experiments were conducted to demonstrate the effectiveness of the proposed method.
