Unsupervised Learning Methods Exam Preparation
Following the principle “You only understood something thoroughly if you can explain it” - here come the prepping notes for Machine Intelligence II. If no sources are indicated, it comes from the lecture slides. Note This was foremostly written for my own understanding, so it might contain incomplete explanations Chapters General Terms and tools PCA PCA Hebbian Learning Kernel-PCA Source Separation ICA Infomax ICA Second Order Source Separation FastICA Stochastic...

DocumentDeck
Today I am excited to announce the launch of DocumentDeck. DocumentDeck solves my own problem with keeping track of invoices and credentials. The documents I receive usually end up on a large pile on my desk or in a huge binder if I have my lucky day. Now I have an easy way of just scanning the documents and having them easily retrievable in the future. Uploading is as easy...

How to serve a website from behind a NAT with a VPS
A common way to run a website behind a NAT as you might find it at home is to configure the router to forward port 80 to your machine. This is not always doable, as you might not have access to the router. If you have access to an external server(for example a cheap VPS), you can route traffic through that by connecting to it via SSH from the local...
