This document discusses artificial intelligence and machine learning tools for .NET developers. It introduces AI tools like Visual Studio Tools for AI and Azure Machine Learning Studio. It also covers pre-built AI with Azure Cognitive Services, custom AI with Azure Machine Learning Service, and conversational AI with LUIS and QnA Maker. The document demonstrates machine learning for .NET with ML.NET and shows a movie recommender example. It also promotes data science VMs, Microsoft Research open data, and the Microsoft AI School.

1. The root of mean squared error (RMS or RMSE) is used to measure the
differences between the model predicted values and the test dataset observed
values. Technically it's the square root of the average of the squares of the
errors. The lower it is, the better the model is.
2. R Squared indicates how well data fits a model. Ranges from 0 to 1. A value of
0 means that the data is random or otherwise can't be fit to the model. A
value of 1 means that the model exactly matches the data. You want your R
Squared score to be as close to 1 as possible.
