What I've learned getting my colleagues up to speed with AI

How do you start with AI when you're a developer and have no idea where to begin? Organize a workshop for your colleagues and challenge them to start exploring machine learning. I certainly learned a ton while organizing the AI learning experience. It was a lot of fun.

I'm building my own deep learning framework and that's crazy

I've embarked on my hardest and most fun adventure ever. I'm going to implement my own deep learning framework. I know most people will call me crazy. But I think this is a challenge that was long coming and I finally got around to it. Wonder why? Read on.

Learn how to build a bot with the new Microsoft Bot Builder Java SDK

Bot builder from Microsoft has been around for a couple of years now. During Microsoft Build 2018 a preview of version 4.0 was launched with support for more languages. Previously you could only build a bot in C# or Node. Now you can build one in Java too. Here's how.

Bring your deep learning models to production with CNTK on Java

Discover how you can use Cognitive Toolkit to bring your models to production with Python and Java.

Time to do it differently, build chatbots with streams

Currently when you want to build a chat bot in Microsoft Bot Builder you have to deal with the rather complicated dialog system. I really don't like it, but there isn't a very

Learn how to visualize your CNTK based neural network

When you're building complex neural networks you often want to visualize them. Visualization offers a great way to debug things like performance bottlenecks, because parts of your network get duplicated by CNTK. Luckely, it is quite easy to visualize a neural network in CNTK. Here's how.

Here's why Microsoft Cognitive Toolkit is the coolest deep learning framework around

Microsoft cognitive toolkit supports loading and saving models in ONNX format, which enables you as a developer to run your trained network on Java and C# with much better overall performance than you can get with Python.

Adventures in AI part 3: How do I know my ML model is any good?

You can train any model you like for your AI solution, but it is only as good as the data you feed it. But how do you measure the performance of a machine learning model? In this third part of the series on AI models I will show you how.

My python setup on Windows 10

Setting up a proper development environment for Python and Data Science projects can be hard on Windows. Python's origin isn't on Windows which shows, but you can get it to work with just a few tweaks. Here's how.

How to quickly build a REST API in Django

Vacation time, an excellent time to learn something new, so I figured, why not build a recipe bot that recommends recipes? For that I needed a way to store recipes that the bot could retrieve. And I figured, why not try to build that in Python with Django?

How-to: run Microsoft Cognitive Toolkit based application inside a Docker image

As part of a Community Hack at Microsoft Denmark people can hack together basic AI models with CNTK. Two fellow MVPs asked me if they could use Docker to work on CNTK applications.

Learn how to build flexible machine learning pipelines in scikit-learn

Setting up a machine learning algorithm involves more than the algorithm itself. You need to preprocess the data in order for it to fit the algorithm. It's this preprocessing pipeline that often requires a lot of work. Building a flexible pipeline is key. Here's how you can build it in python.

5 easy steps to start editing python notebooks over SSH

When you work with Linux machines on Amazon EC2 or Azure over SSH and want to edit interactive python code you've got a challenge. There is vim and other console based editors, but that might not be what you want. Here's how you can edit python code in your browser over SSH in 4 steps.

How to setup tox on Windows with Anaconda

When you are developing packages for Python you need some way to test whether your package works on someone else's computer. Tox is a great tool for this, but doesn't work well with Anaconda. With some basic steps however you can have your code tested on tox without much trouble.

Machine learning tips: How to quickly generate a bag of words

Natural language processing is all about text. But it doesn't use the text itself. You need vectors of numbers, for example a bag of words. This can be easily built with a dictionary and some for loops. But there is an easier way.

Run Rider even with the new .NET Core 2.0 SDK

This week .NET Core 2.0 alongside with ASP.NET Core 2.0 was released. A lot of improvements were made to the runtime and the size of the standard libraries has increased

Which celebrity are you? A celebrity scanner built with Clarifai

When it comes to building solutions with AI you want to be smart. Don't just run in there and start using Tensorflow. There are many good solutions such as Clarifai out there that don't require a lot of work, but still produce superior results.

How to generate PDF documents in ASP.NET Core

A customer I work for wants to generate a set of attachments for an e-mail we need to send to the clients of that customer. We ended up using DinkToPdf with the ASP.NET Core Razor Template Engine to build a PDF generation microservice.
