The main reasons were that I want to be able to search my notes and access them everywhere I am. … Continue reading Evernote: my almost perfect productivity tool

Tensorflow CNN and lime on my own cat & dog images

In a recent blog post I evaluated the R package lime on a regression data set. After this I wanted to go deeper (pun not intended ;)) and use lime on more complicated models such as deep neural networks. I have started collecting cat and dog pictures a long time ago with the idea in … Continue reading Tensorflow CNN and lime on my own cat & dog images

Exploring lime on the house prices dataset

Pretty recently I found a paper with the title “Why Should I Trust You?”: Explaining the Predictions of Any Classifier. The topic of interpretability is very important in the times of complex machine learning models and it’s also related to my PhD topic (reliability of machine learning models). Therefore I wanted to play around with … Continue reading Exploring lime on the house prices dataset

First steps with DaVinci Resolve for video editing

A couple of months ago I took some videos with a GoPro during we moved all of our stuff into our new apartment. I thought it would look especially cool to have a time lapse video of me filling my bookshelf. Before I could share the video, I wanted to edit it a little bit. … Continue reading First steps with DaVinci Resolve for video editing

Find closest date before or after event (MATLAB)

It’s the second time since I have been using MATLAB that I need to find the closest date to a given target date in an array. Of course I didn’t remember how I did it the last time and I couldn’t find a solution that suited my needs on the internet. So I decided to … Continue reading Find closest date before or after event (MATLAB)

Learning Club 16: Genetic Algorithms

Some time ago I published a blog post with the title Know your data structures!. In this previous post I explained how I improved the running time of a genetic algorithm. I promised to go more into detail about other noteworthy things in the code in a separate article since not everything was straightforward when … Continue reading Learning Club 16: Genetic Algorithms

Know your data structures!

Just a few days ago I stated the following on Twitter: Just reduced the runtime of an algorithm from 9 hours to 3 min. by using a different data structure… Know you data structures 🙂 #rstats — Verena Haunschmid (@ExpectAPatronum) May 1, 2017 Since my tweet has been liked and shared a lot, I thought … Continue reading Know your data structures!

Copy environment variables between SSIS catalogues on different servers

Problem Usually when developing SSIS packages, you want the project to run on different servers, e.g. development, test and production server. If you have many environment variables creating all of them is tedious and unnecessary work. I’ll show you how you can copy environment variables between SSIS catalogues that are located on different servers. Solution … Continue reading Copy environment variables between SSIS catalogues on different servers
