- 3. Cameron Vetter I have20 years of experience using Microsoft tools and technologies to develop software. I have experience in many roles including Development, Architecture, Infrastructure, Management, and Leadership roles. I've worked for some of the largest companies in the world and for small local companies getting a breadth of experience in different Corporate Cultures. Currently, I work at SafeNet Consulting, where I get to do what I love... Architect, Design, and Develop great software! I currently focus on Microservices, SOA, Azure, Cognitive Toolkit, and Kubernetes. Principal Cloud Consultant

- 7. Wikipedia’s Definition Machine learning (ML)is the scientific study of algorithms and statistical models that computer systems use to effectively perform a specific task without using explicit instructions, relying on patterns and inference instead. Machine learning algorithms build a mathematical model of sample data, known as "training data", in order to make predictions or decisions without being explicitly programmed to perform the task
- 8. Patterns and Inference Relieson Patterns and Inference not explicit instructions or Algorithms Model Based The training is used to train a model that is the core of the Machine Learning Model Not Just Glorified Statistics We borrow many terms from statistics such as biases, weights, models, and regressions, but that does not make this segment of statistics, ML is a segment of computer algorithms Training Data Uses some form of training data to learn from to make its decisions

- 16. REST Services Isolate yourMachine Learning code from other code creating appropriate boundaries and allowing it to be independently released. Encapsulated Consumers should not have to understand the machine learning, present them a simple RESTful interface like any other service designed for consumption. Simple Unless you can’t isolate the code. When embedding in an IOT Edge device your Machine Learning can not be isolated, but can still have logical boundaries, such as using Docker Containers. Integrated
- 17. N-Tier Add this serviceinto your business logic tier. Can also fit well into this architecture. Others Onion, Event Driven, CQRS, ESB, Spaghetti, etc… Services / MicroServices Fits well with my recommendation to wrap this in a RESTful service, very easy to turn that into a Service Architecture
- 18. IAAS / PAAS PlatformAs A Service is a great choice, but Infastructure As A Service can work well also. Containers Fits well in a container, consider keeping your model in one container and your service in a separate container. Edge Devices Embed your Machine Learning into IOT devices, laptops, web pages, or any other devices on the Edge.

- 21. 21 Design for Replacement Yourteam will want to iterate often, especially in the beginning. Plan your versioning strategy as though you are swapping out you ML training daily. Don’t tightly couple your ML Service to your ML Training!
- 22. A/B Testing Assume you willneed A/ B Testing. ML Models that perfectly during testing can fall apart in the real world! Which Performs Better?
- 23. What Do Ineed to Version? Standard Source Control procedures and labeling. Cloud Storage. Each Data Set Version should be independently accessible. Serialize your model and check it into its own Source Control Repo. Label Appropriately! Serialize your training and scalars and check them into Source Control with the Model. Code Data Model Training
- 24. Interface Compatibility • Standardize onModel Inputs and Outputs. • Consider Model Interface changes to be a breaking change. • Breaking changes will require versioning the service.
- 25. Bias and OtherRisks
- 26. Bias is anerror from erroneous assumptions in the learning algorithm. High bias can cause an algorithm to miss the relevant relations between features and target outputs. This is referred to as underfitting. Bias Source: https://en.wikipedia.org/wiki/Bias%E2%80%93variance_tradeoff
- 27. Variance is anerror from sensitivity to small fluctuations in the training set. High variance can cause an algorithm to model the random noise in the training data, rather than the intended outputs. This is referred to as overfitting. Variance Source: https://en.wikipedia.org/wiki/Bias%E2%80%93variance_tradeoff
- 28. Real world datais messy. Expect to have too little data potentially causing Bias + Variance, or missing data points in a data set. Data is the hard part of machine learning. Incomplete Data

- 30. Don’t start byhiring a Data Scientist. There are many tools that can help people with less expensive skill sets. Developers, Data Analyst’s, and Data Architects will be able to help you get started and identify when you need a Data Scientist. Data Scientists
- 31. Start with offthe shelf prebuilt services. Select problems that can fit this solutions, and get some quick wins. Prebuilt ML Services Use some Neural Networks available on GitHub. Allow your team to get used to the language / tool chain. Prebuilt Neural Networks Create a Proof of Concept within your domain leveraging High Level Libraries to build your own Neural Network. POC with High Level Libraries Use these high level libraries to create full production systems. Don’t bother with the low level libraries, unless a specific need forces you to. Full Solutions Start Small / Work smart and save money / Source: https://bit.ly/netflixjupyter/
- 32. Prebuilt Strategy I recommend usingthe Façade Design Pattern to ensure that you are loosely coupled to the prebuilt service you are consuming. Don’t get tightly tied into a platform, especially when you are experimenting!
- 33. • Pick avery popular library like Keras • Integrate into a REST Service • Plug the REST Service into your Current Architecture and Current Infrastructure High Level Library Strategy
- 34. ONNX is aopen format to represent deep learning models. With ONNX, AI developers can more easily move models between state-of-the-art tools and choose the combination that is best for them. ONNX is developed and supported by a community of partners. ONNX.AI Be Flexible
- 35. • Don’t buya ton of GPU’s and Servers! • Leverage the Cloud To Train • Use Batch AI and Data Science VM’s in Azure Training
- 36. • Reach consensuson your versioning strategy up front. • Use separate containers for your ML Service and model • Plan for A/B Testing • Have the ability to instantly roll forward or backward Up Front Versioning Strategy
- 37. Use a uniformversioning convention that includes time and date. For Example: (datetime)-(model name)- (model version)- (training script id).json Versioning Scheme
