Speaker: Jeffrey Tumminia
Title: City Tech, Internships, and Beyond
Abstract: Jeffrey Tumminia is a City Tech alumnus with a degree in Applied Math. In this talk he will discuss his time at City Tech and give general advice for students interested in math and computer science related careers. There will also be time for a Q&A session.

Date: February 28, 2019
Speaker: Charlie Meyers
Title: Software Engineering, Data Science, and Careers in Mathematics
Abstract: This week’s presentation will feature Charlie Meyers, who graduated from NYCCT’s Applied Mathematics program last year. He’s now a Master’s student at CUNY’s School of Professional Studies, studying Data Science. He will share some original research on jobs in the Math and Computer Science fields and discuss his experience interviewing at a multitude of tech companies. This research dives deep into the Bureau of Labor Statistics data to see what kind of jobs are available to recent graduates, as well as what tools, techniques, and languages one must know in order to land a job in the software engineering field. We will also examine what skills will land you a high-paying job in the giant, growth field of data science/software-engineering. Because he is moving to Germany to work at Audi’s self-driving car division, he will speak briefly about the international opportunities of STEM graduates. Time will be allocated at the end for students to ask questions of the Applied Math program, CUNY SPS, Data Science, or job interviews. Stop by, grab a slice of pizza, and learn about the exciting world of health insurance, a salary, and coding for money.¬†

Title: Celestial Navigation
Abstract: In today’s world less and less mental and physical effort is needed to cope with one’s needs. Alexa answers all your questions, advises you what to do and how to do it. Doors open for you, food is delivered to your door, toilet seats can close themselves, cars drive without you, and soon Robots will perform many of your tasks. There is less and less for you to do but maybe sit, watch movies and tv, and live vicariously, watching how people coped with their needs years ago. Does this sound appealing? Wouldn’t you like not to depend on electronics and have the skill that enables you to find your location in a more romantic way by gazing at the heavens? People have been doing this for thousands and thousands of years. GPS has only been with us for less than 50 years. Come be introduced to Celestial Navigation using heavenly bodies to locate your position on the earth. It may come in handy some day when your phone runs out of charge.

Title: An Introduction to Git
Abstract: Git is a popular version-control system used to track changes in a set of files (a repository). In this brief introduction to Git, we will cover the basic commands for creating, updating, and working with others on a repository. This will be an interactive talk, so we encourage participants to bring their laptops to follow along (be sure to install Git before attending). We will also have laptops available with the appropriate software already installed.

Title: Two Years of Bayesian Bandits for E-commerce
Abstract: At Monetate, we’ve deployed Bayesian bandits (both noncontextual and contextual) to help our clients optimize their e-commerce sites since early 2016. This talk is an overview of the lessons we’ve learned from both the processes of deploying real-time Bayesian machine learning systems at scale and building a data product on top of these systems that is accessible to non-technical users (marketers). This talk will cover:

  • The place of multi-armed bandits in the A/B testing industry,
  • Thompson sampling and the basic theory of Bayesian bandits,
  • Bayesian approaches for accommodating nonstationarity in bandit feedback,
  • User experience challenges in driving adoption of these technologies by nontechnical marketers.

We will focus primarily on noncontextual bandits and give a brief overview of these problems in the contextual setting as time permits.
