ML.NET Samples

ML.NET is still new, and as we are developing it, we would love to get your feedback! Please fill out the brief survey below and help shape the future of ML.NET by telling us about your usage and interest in Machine Learning and ML.NET.

Take the survey now!

At the end of the survey, you can leave your name and e-mail address (optional) so that an engineer on the .NET team can reach out to you to talk a little bit more about your experiences and thoughts. We appreciate your contribution!


ML.NET is a cross-platform open-source machine learning framework that makes machine learning accessible to .NET developers. In this GitHub repo, we provide samples which will help you get started with ML.NET and how to infuse ML into existing and new .NET apps.

There are two types of samples/apps in the repo:

  • Getting Started - ML.NET code focused samples for each ML task or area, usually implemented as simple console apps.

  • End-End apps - Real world examples of web, desktop, mobile, and other applications infused with Machine Learning using ML.NET

The official ML.NET samples are divided in multiple categories depending on the scenario and machine learning problem/task, accessible through the following table:

ML Task

Description

Scenarios

Binary classification

Binary classification chart
Task of classifying the elements of a given set into two groups, predicting which group each one belongs to.

Sentiment analysis     C#     F#   Getting started icon

Spam Detection     C#     F#   Getting started icon

Fraud detection    C#    F#    Getting started icon

Heart disease detection    C#    F#    Getting started icon

Multi-class classification

Multi-class classification
Task of classifying instances into one of three or more classes, predicting which group each one belongs to.

Iris flowers classification    C#    F#    Getting started icon

MNIST    C#    F#     Getting started icon

Regression

The task is to predict a numeric value with given input variable data. It is widely used for forecasting and 'how much / how many' predictions.

Price prediction     C#     F#   Getting started icon

Sales forecast     C#    End-to-end app icon

Demand prediction     C#    F#    Getting started icon

Recommendation

Recommendations icon
Recommender systems are typically based on content based and collaborative filtering methods. A collaborative method predicts what items/products a user might like based on his past actions/likes/ratings compared to other users.

Clustering

Clustering plotting
ML task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar to each other than to those in other groups. It is an exploratory task. It does not classify items across particular labels.

Anomaly detection

Task's goal is the identification of rare items, events or observations which raise suspicions by differing significantly from the majority of the data.Usually problems such as bank fraud, structural defects or medical problems

Spike Detection-PowerMeter Readings     C#     F#   Getting started icon

Ranking

Ranking logo
Construction of ranking models for information retrieval systems so the items are ordered/ranked based on user's input variables such as likes/dislike, context, interests, etc.

Coming soon

Deep Learning

DeepLearning logo
Deep learning is a subset of machine learning. Deep learning architectures such as deep neural networks, are usually applied to fields such as computer vision (object detection, image classification, style transfer), speech recognition, natural language processing and audio recognition.

Cross Cutting ML.Net Samples: The below samples are created for cross cutting scenarios like Scalable WebAPI services, Datasets stored in Database etc.

NuGet feed configuration: Usually you just need to use the regular NuGet feed (https://api.nuget.org/v3/index.json), however, during a few days before releasing a minor release (such as 0.9, 0.10, 0.11, etc.) we'll be using Preview NuGet packages available in MyGet (such as 0.11.0-preview-27128-1), not available in the regular NuGet feed.

If that is the case, please use this MyGet feed in Visual Studio or your NuGet feed configuration:

https://dotnet.myget.org/F/dotnet-core/api/v3/index.json


Additional Community Samples

In addition to the ML.NET samples provided by .NET Foundation, we're also highlighting samples created by the community shocased in this separated page: ML.NET Community Samples

Those Community Samples are not maintained by .NET Foundation but by their owners. If you have created any cool ML.NET sample, please, add its info into this REQUEST issue and we'll publish its information in the mentioned page, eventually.
