May 2016 Meetup
Kate Ergle presents Tableau:
The talk will be about an important part that cannot be skipped when fitting models to your data - exploring the data set. The best way to do it is with interactive analysis. This can and needs to be done also when analyzing Big Data - the secret to that is random sampling. The emphasis in this talk will be on Tableau which is a business intelligence software that is not very complex but is very powerful.
