Latest Patents

Yafu Li holds a patent for a method titled "Dynamically recalibrating machine learning model parameters." This patent discusses methods and systems for dynamically adjusting machine learning model parameters. The process involves a server executing prediction models to analyze network operations from various data feeds. It identifies the likelihood of these operations being fraudulent or malicious. The server monitors performance data and evaluates whether the performance values meet defined thresholds. If the performance data fails to meet these thresholds, the server employs a function-generation machine learning model to predict a threshold modification function. This function is then applied to adjust the relevant thresholds, enhancing the accuracy and efficacy of the prediction models.
