Is data scientist just a statistician who lives in San Francisco and data science just statistics on a Mac? This talk will provide some answers and thoughts related to this question. The speaker will share practices and lessons learned as a statistician working on big/fast data problems while wearing the data scientist title.

The first part of the talk will cover techniques and concepts that are useful in data science and big/fast data analytics but are less considered or embraced by traditional statistical world. The speaker will dive into both stream (online) and batch (offline) computing paradigms to illustrate the potential gap. Practical examples based on my industrial experience will be provided to help with the presentation. The second part will briefly introduce the big data "A" team, namely Apache Spark, Apache Cassandra and Apache Kafka, a set of open source software packages that are crucial for the recent advancement in big/fast data analytics.

Short Bio of the Speaker

Part of his dissertation work on optimizing Kidney Paired Donation (KPD) programs was awarded the IBS (ENAR) distinguished paper award. After his doctorate, John joined Google to help evaluate and improve its search products, where he was a lead data scientist for search suggest and search feature (user experience) projects. John left Google for Caspida, an early-stage startup in enterprise security (later acquired by Splunk), where he serves as a principal data scientist to tackle challenge machine learning problems in cyberattacks. John is passionate about applying statistical learning methods with open-source technologies in the "big data" world.
