Deep Learning Subset of machine learning that's based on artificial neural networks. 

What is Computer Vision? Computer vision is a field of artificial intelligence that trains computers to interpret and understand the visual world. 

In transfer learning, a model trained for one task is used as a starting point for a different task. What is Transfer Learning? 

PyTorch is an open-source deep learning framework originally developed by Meta AI, and now part of the Linux Foundation. What is PyTorch? 

ONNX is an open format built to represent machine learning models. It defines a common set of operators and a common file format to enable AI developers to use models with a variety of frameworks, tools, runtimes, and compilers. What is ONNX?

What is Azure Machine Learning? Set of Azure Cloud Services Python SDK AML Studio or Interface of your choice That enables you to:  Prepare Data  Manage Models  Build Models  Track Experiments  Train Models  Deploy Models 

Azure ML service Key Elements Workspace Models Environments Experiments Deployment Pipelines Datastores Compute Target Data Labelling 

Interface 

ML Pipelines An Azure Machine Learning pipeline is an independently executable workflow of a complete machine learning task. Subtasks are encapsulated as a series of steps within the pipeline. An Azure Machine Learning pipeline can be as simple as one that calls a Python script, so may do just about anything. Workflows of steps that can use Data Sources, Datasets and run on Compute targets 

Create a step / component Input Output Runs a script on a Compute Target in a Docker container. Parameters 

Create a pipeline Dataset of Simpsons Images Train the Model with a PyTorch model Register the model Blob Storage Account Model Management model Convert Model To ONNX 

Azure ML Designer What is the Azure ML Designer? AML Designer is an UI interface which enables you to build machine learning pipelines with drag-n-drop experience and simplify the publishment and deployment of your pipelines.
