What to Expect from This Prezzy? High-level overview of Machine Learning Why you would need ML as a developer ML resources, best practices, tools, platforms, and frameworks for developers. Demo session on using ML for developers (time-constrained) [OPTIONAL] Link to the slides for the prezzy. 

Machine Learning why, what, how 

Why Machine Learning Input What is the biggest dessert in the world? ML Software Learns from the input; in this case, infers ‘desert’ instead of ‘dessert’. Output “Antarctic Desert” To deal with the complexity and uncertainty of the users of our products… For example; 

Before Defining ML, Let Me State What it is NOT… 

No be “Juju” Cannot magically solve all problems you throw at it. No be “Terminator” No be “job snatcher” Does not have what it takes to take over the world and hold it captive. Can only take on repetitive tasks that are in jobs rather than full jobs themselves. 

What ML IS… 

Let’s first think about how we learn, as humans… 

ML is simply computers using data to answer questions. Machine Learning Model (Or Algorithm). Machine Learning Generated Answers. 

How ML “Learns”? 

Input Output “Bole” Recognizes and learns the patterns that are common across and associate the inputs. A lot of Bole images taken at varying angles and in varying styles. Learns the feature common across each and every image, and how they associate with each other. Can recognize entirely new Bole images it hasn’t learnt about before and tag them “Bole”. •Text •Number •Audio •Videos •Images 

Machine Learning is All Around You… Virtual Assistants; Siri, Cortana, Google Assistant, Alexa… Recommendation Systems; YouTube, Netflix, Twitter, Facebook… Search engine results; Google search, Bing… 

ML has been around for a while. It became better, because… Big Data Better Computing Infrastructure Improved Learning Algorithms Accessible Tools & Frameworks 

Why ML for Developers? 

Contrast in Workflows Between Traditional Programming and Machine Learning…

Requirements Engineering Design (Get Data and preprocess it) Implementation (Learning Algorithm; ML Model) Evaluation And Fine-tuning Outputs Production (Continuous monitoring & Maintenance) Machine Learning Engineering Typical Workflow Machine Learning 

Requirements for a Typical Machine Learning Engr./Dev Mathematics Statistics Coding Skills Python, R, Julia Software Engineering Principles, tools, and best practices . 

Scenarios You Would Probably Need ML, as A Developer… 

Scenario 1 Boss asks “Hey, so we have a bunch of data on customer transactions. Can you help us build a model that can predict which of our customers will buy our products? Easy, right?” One-off Model 

Scenario 2 PM: “Hey, so we are building this software and I think this facial recognition feature would be too complex for us to program by rules. You could embed some ML into the software so we won’t have to kill ourselves, yes?” Embedded Model 

Scenario 3 Boss: “Hey, so we noticed that this Machine Learning is the next software revolution. We kind off want you to become a full-time ML engineer for the company’s new AI division. Too much to ask?” Full-time Beast Model 

Most Common ML Tools and Frameworks for Developers… 

Frameworks/Libraries 1. TensorFlow ▪ TensorFlow APIs ▪ TensorFlow.js ▪ TensorFlow Lite 3. Scikit-Learn 2. Keras 1. Google ML Tool Kit 2. iOS CoreML 4. Weka 4. Apache Spark ML Lib 5. MLflow 5. AWS ML APIs Tools 3. Google Cloud ML APIs 

Cloud/Serverless ML Platforms 1. Microsoft Azure ML Studio 2. Google Cloud AutoML 3. Google BigQueryML 5. Amazon AI/SageMaker 4. Google Cloud AI Platform 

An Important ML Methodology for Developers... 

Transfer Learning: an algorithm transferring the knowledge of a particular problem to another algorithm. Basically... 

Transfer Learning The intuition behind it How it works... When to Use it, as a developer... 

Constraints for Using ML for Developers… You need *lots* of data and compute infrastructure to get it to work quite well. It is quite difficult to operationalize ML software and get them to production, they break drastically if not monitored. It is a rapidly evolving field, new tools and techniques are emerging almost every time. It’s hard to keep up. Need to explain results and data privacy of the software becomes extremely important for the developers. 

Important ML Notes to Consider… 1. Machine Learning is way more than just the tools. 2. ML models must be built responsibly. 3. ML solutions need to be iteratively monitored and updated. 4. MLOps (Machine Learning operationalization) is possible. 5. Explainability and data privacy are extremely important ML practices. Credits: Jade Abbott (@alienelf) 

Another Important Point to Note as a Developer... To get it to work for your product users, it still needs to integrate with other existing solutions like your; ● Mobile applications, ● Website or web applications, ● IoT or Edge devices. Machine Learning isn’t always stand-alone solution for your users!!! 

Uhm.. Steve, So Should I learn ML as a Developer? As a developer, if there is no absolute requirement for you to learn it, then you should not. Treat ML as a set of tools. Like any other tool, be aware of the problems it can solve and those it cannot. 

To Conclude… 

ML is about helping algorithms understand our problems, and then take the most efficient steps to solve the problems—this is the new age of software where systems are smart and adaptable to the complex world around us.
