Title: The Innovations of Pengxiang Xu

Introduction

Pengxiang Xu is a notable inventor based in Huntington Beach, California. He has made significant contributions to the field of data processing and analysis, particularly in the realm of domain name system (DNS) data. His innovative approach has led to the development of a unique patent that addresses the challenges of identifying malicious domains.

Latest Patents

Pengxiang Xu holds a patent titled "Volumetric clustering on large-scale DNS data." In this approach, a processor receives a set of normal domains, a set of suspicious domains, and a set of malicious domains. It labels each domain of the set of normal domains as normal, producing a labeled set of normal domains. Each domain of the set of suspicious domains and the set of malicious domains is labeled as malicious, resulting in a labeled set of malicious domains. The processor samples a preset percentage of the labeled set of normal domains, producing a sampled set of normal domains. It aggregates the sampled set of normal domains and the labeled set of malicious domains, producing a set of aggregated domains. The set of aggregated domains is filtered using hit size, inter-arrival-time, and univariate volumetric filters, resulting in a set of filtered domains. Finally, the processor determines a cluster of a set of clusters to which each of the set of filtered domains is to be assigned using a trained K-shape model. This patent showcases his expertise in data analysis and machine learning.
