Latest Patents

Nishant Kumar holds a patent for "Fraud detection methods and systems based on evolution-based black-box attack models." This patent involves various embodiments that relate to methods and systems for generating adversarial samples. The method performed by a server system includes accessing a set of payment transaction samples from a transaction database. It also includes initializing a plurality of encoders, with the weights of each encoder being randomly initialized. The process further involves computing a set of initial adversarial samples using the plurality of encoders based on the payment transaction samples. Additionally, the method optimizes the plurality of encoders to generate evolved encoders and computes fitness scores for these encoders. Ultimately, it determines a top evolved encoder based on the fitness scores and generates final adversarial samples using this top encoder.
