Data Con LA 2020 Description Machine learning is an essential skill in today's job market. But when it comes to learning Machine Learning, beginners get lot of conflicting advice. I have been teaching ML for software engineers for years. In this talk *I will dis-spell some of the myths surrounding machine learning *give you solid, tangible plan on how to go about learning ML *and give you good pointers to start from *and steer you away from common mistakes Speaker Sujee Maniyam, Elephant Scale, Founder, Principal instructor

Traditional Programming vs. Machine Learning Here is an example of spam detection rule engine The rules are coded by developers There could be 100s of 1000s of rules! if (email.from_ip.one_of("ip1", "ip2", "ip3")) { result = "no-spam" } else if ( email.text.contains ("free loans", "cheap degrees")) { result = "spam" } 6

Traditional Programming vs. Machine Learning Here is how we detect spam using ML We don't explicitly write rules Instead, we show the algorithm with spam and non- spam emails Algorithm 'learns' which attributes are indicative of spam Then algorithm predicts spam/no-spam on new email 7

ML Engineer Skill Set: AI A good ML engineer needs good understanding of machine learning and deep learning algorithms See next slide for explanation What if I don't know enough Math? Even though ML and DL are built on advanced math, we don't need deep understanding of the mathematical theories to use the algorithms Because the tools and algorithms have gotten so much better and easier to use Practical use of algorithms recommended 13

Deciding ML Services Decide the spectrum of the service you'd like Based on desired control, flexibility and agility Renting infrastructure: Get a virtual machine with GPU and train our own model Renting a ML service: Use a pre-built model Say use a 'computer vision' model that is offered by cloud vendor This is basically 'ML as Service' 19

ML Engineer Skill Set: Big Data & Distributed Computing Training large scale models may use large amount of data And training can be computationally intensive For example, let's say working with 1GB data on a laptop takes 1 hr How about we have 1TB of data? it will definitely not fit into laptop's memory We would need to do it distributed on a cluster of machines 20
