Data visualization

A picture says more than a thousand words..but what exactly do you want to visualize?
I have seen a lot of examples of very good bus also very bad visualizations. For example a pie chart with more than 3 or 4 categories is not readable in my opinion. Because people are better at comparing lengths than areas, a bar chart is a better choice in many cases. I am using rainbow colors only occasionally since there is no “greater than”¬†ordering in colors so it’s hard for a human to compare quantitative data. Until now I have used R/shiny, D3js, plotly, QlikView and Tableau for my data visualizations with most experience in the first 2.

Machine learning

Need to make predictions based on historical data? Or want to explore your data for certain patterns?

Machine learning is a discipline that can be applied to a lot of domains. IBM Watson changes the world of healthcare by applying machine learning. Many companies are working on self driving cars, which are all based on some sort of machine learning.

I have experience with supervised, unsupervised and reinforcement learning. In recent projects I have for example predicted nitrate level from image analysis and I have build a fraud detection algorithm based upon historical transactions.

Remote training

Are you interested in visualizing your data yourself? Do you want to start with R programming?

I offer remote training for a variety of topics related to R. In only a half day, you can be up and running with R and start with analyzing your data.

Topics for beginners include: introduction to R/RStudio, Git, RMarkdown, and Shiny. Please contact me in case of specific training needs.
