Lead, architect, and develop new data-intensive techniques with machine learning and visual analytics. From 2018 to Present: Condati Inc. Principal Data Scientist• Anomaly Detection (TensorFlow deep learning, anomaly search, and prediction)Created live “Consecutive Anomaly Auto-Detection” dashboard from large revenue data streams on a cloud platform. Built learning models for better forecasting. Customers are able to catch sequence of abnormal events using confidence bands. • Funnel Process (business models, optimized B2B sales pipeline)Built a real-time “Multi-Stage, Multi-Scale, and Auto-Linking” pipeline to visualize live business deals moving from a “new deal” to a “closed won”. This technique of optimizing B2B sales process time translates directly into more sales and more revenue.

(1) From 2015 to 2016: HP Inc. Immersive Experience Lab. Master Engineer• Built Smart Office (Hadoop, access millions of IoT sensors across thousands of offices)Derived “Exception Bands” to optimize and predict energy consumption about ~18% savings.• HP Market-share risk analysis on Supply Chain for early warnings.(2) From 2002 to 2015: HP System Analysis Lab. Senior Scientist• Auto Security Threat Detection (Streaming millions of Internet traffic/sec)Created ML models on Hadoop/Spark platform. With Multi-dimensional scaling, Distance matrix, hierarichical DBSCAN, LSTM neural networks to find both known and unknown threats. Adopted by HP Cyber Defense Center.• Predictive and Risk Analysis (Achieved ~80% accuracy)Derived "Peak Preserving" algorithms to improve SaaS system performance. (Adidas, Goodyear)• Live Text Mining (AWS, ~250k tweets/min)Employed AWS for reading live email and tweets reviews. Reviews are combined as topics. Integrated to Vertica's software offering.• Patient-Centered Healthcare on Adverse Drug Events, Readmission (Spark, Machine Leaning)Classified patients with similar behaviors.• Visual Analytics (combined machine learning and visual analytics)Adopted by Visa: fraud detection; Southwestern: oil/gas production.12 Technical Achievement Awards, 3 Innovation Awards, 8 IEEE papers, and over 50 US patents.
