📰 I am on the market with expected graduation in Spring 2023. I am broadly interested in machine learning, data mining/science, and information systems positions. I can work in the U.S., and Canada without sponsorship; please reach out if you have an open opportunity! Contact me by Email (zhaoy [AT] cmu.edu) or WeChat (微信) @ yzhao062.

Who am I (赵越)? I am a 4-th (final) year Ph.D. candidate at Carnegie Mellon University (CMU). Before joining CMU, I earned my MS degree from University of Toronto (2016) and BS degree from University of Cincinnati (2015), and worked as a senior consultant at PwC Canada (2016-19). I am an expert on anomaly detection (a.k.a outlier detection), machine learning systems (MLSys), and automated machine learning (AutoML), with more than 7-year professional experience and 30+ papers (in JMLR, NeurIPS, VLDB, MLsys, etc.) I appreciate the generous support from CMU Presidential Fellowship and Norton Labs Graduate Fellowship.

At CMU, I work with Prof. Leman Akoglu for automated data mining, Prof. Zhihao Jia for machine learning systems, and Prof. George H. Chen for general ML. I am a member of CMU automated learning systems group (Catalyst) and Data Analytics Techniques Algorithms (DATA) Lab. Externally, I collaborate with Prof. Jure Leskovec at Stanford and Prof. Philip S. Yu at UIC.

Contributions Machine Learning Systems for Anomaly Detection and Out-of-distribution (OOD) Detection: I use machine learning systems (MLSys) techniques to support large-scale, real-world outlier detection applications in security, finance, and healthcare with millions of downloads. I designed CPU-based (PyOD), GPU-based (TOD), distributed detection systems (SUOD) for tabular (PyOD), time-series (TODS), and graph data (PyGOD). To understand the characteristics of OD algorithms, I co-author large-scale benchmarks for tabular data (ADBench), time-series data (paper), and graph data (BOND). My work has been widely used by thousands of projects and applications, including Amazon, IBM, Morgan Stanley, and Tesla. See more applications.
