Editor's Notes
- #4: If you've never used Azure Machine Learning Studio before, this session is for you. This session is not for Advanced users. We will not be covering algorithms here.
- #5: Quick Evaluation: https://studio.azureml.net/Home/Anonymous Free Workspace: https://studio.azureml.net/Home Standard Workspace: https://azure.microsoft.com/en-us/documentation/articles/machine-learning-create-workspace
- #6: Azure Machine Learning is a cloud-based predictive-analytics service that offers a streamlined experience for data scientists of all skill levels. It's accompanied by the Azure Machine Learning Studio (ML Studio), which is a browser-based tool that provides an easy to use, drag-and-drop interface for building machine-learning models. It comes with a library of time-saving experiments and features best-in-class algorithms developed and tested in the real world by Microsoft businesses such as Bing. And its built-in support for R and Python means you can build custom scripts to customize your model. Once you've built and trained your model in the ML Studio, you can easily expose it as a Web service that is consumable from a variety of programming languages, or share it with the community by placing it in the Cortana Intelligence Gallery.

- #8: PROJECTS - Collections of experiments, datasets, notebooks, and other resources representing a single project EXPERIMENTS - Experiments that you have created and run or saved as drafts WEB SERVICES - Web services that you have deployed from your experiments NOTEBOOKS - Jupyter notebooks that you have created DATASETS - Datasets that you have uploaded into Studio TRAINED MODELS - Models that you have trained in experiments and saved in Studio SETTINGS - A collection of settings that you can use to configure your account and resources.
- #12: Good book -- and free! Another recommended book on Azure Machine is Learning is "Predictive Analytics with Microsoft Azure Machine Learning " (https://www.amazon.com/Predictive-Analytics-Microsoft-Machine-Learning/dp/1484212010).
- #20: https://how-old.net/# offers a great example of machine learning in action. Created by Microsoft, the site uses advanced image-recognition techniques to analyze photos you upload and then uses an ML model to "predict" the ages of the people in the photos.
- #21: The Azure ML Cheat Sheet helps you pick the right algorithm for a model, even if you're not a trained data scientist. One example is if you want to use a set of input values to predict an output value from a continuous set of values (e.g., a person's age), use linear regression. But if you're more interested in the distribution of the output, you might use fast forest quantile regression instead. An example of when you would use the latter is using growth charts to assess child development. "Abby's height is in the 10% quantile of the heights of kids her age." Classification algorithms, by contrast, are used to predict a value from a discrete set of values -- for example, classifying an e-mail as spam or not spam.
