Latest Patents

Yang's latest patents include groundbreaking technologies aimed at detecting artificial intelligence-generated text and computer code. The first patent, titled "Systems and methods for detecting artificial intelligence (AI) generated text," outlines a method where a candidate text can be truncated to create a prefix and a remainder text. By employing a truncation module, regenerated model texts can be created using the prefix text through an AI text generation model. The detection results are predicted by comparing n-gram similarities between the regenerated model texts and the remainder text, allowing for the identification of AI-generated text through explanatory texts based on these results.

The second patent, "Systems and methods for detecting artificial intelligence (AI) generated computer code," describes a process where lines of code can be masked from a candidate code to generate perturbed codes. An AI code generator model is then used to create machine-filled codes from these perturbed codes. The probabilities of the candidate code and the machine-filled codes being AI-generated are predicted using a surrogate model. This innovative approach allows for distinguishing AI-generated code by comparing the probabilities against a detection threshold.
