Learning Path: Introduction to AI/ML for Software Engineers

Location: Seacliff A

Duration: 9:00am - 4:00pm

Day of week: Thursday, Friday

Level: Intermediate

Key Takeaways

  • Ability to evaluate problems and formulate machine learning solutions to relevant problems
  • Experience in implementing machine learning applications with light use of popular toolkits
  • Intuition around decisions around machine learning algorithm/technique selection given the problem scope and objectives
  • Understanding of feature engineering techniques to solve common problems in data wrangling and system scaling
  • Ability to implement end-to-end applications that utilize data sets to generate actionable insights

Prerequisites

Required by attendees:

  • The latest version of Virtualbox (or other comparable desktop virtualization software) Installed
  • Administrative access on your laptop with external USB access allowed
  • At least 20 GB free hard disk space
  • At least 4 GB RAM (the more the better)

Introduction to AI/ML for Software Engineers" is a fast-paced learning path on machine learning from a software professional’s point of view. The class is designed with the goal of providing students with a hands-on introduction to machine learning concepts and systems, as well as giving them the practical skills to walk away with the foundational skills to embark on ML projects in a professional setting.

Over the course of two days, attendees will be put through several hands-on exercises that stimulate learning through writing and executing code, instead of passive lectures. Students will get first-hand experience at cleaning data, implementing machine learning programs, and solving real problems in tuning, deploying, scaling, and maintaining machine learning systems.

Each attendee will be provided with a comprehensive virtual machine programming environment that is preconfigured for the tasks in the learning path, as well as any future machine learning experimentation and development that they will do. This environment consists of all of the most essential machine learning libraries and programming environments friendly to even novices at machine learning. As a capstone at the end of the session, students have a chance to formulate and embark on implementing a real machine learning system, from data collection to deployment.
