Image Classification Tutorial

[Valentin Schalk]

Hello,

unfortunately the link to the image data is not working. I hope you can fix this.

Thank you!

ps: also the link “Random Forest R vs. Python” is not working.

Hi Valentin,

Both of the links have been fixed! Sorry for the inconvenience, I hope you are able to access the data now and continue with the rest of the tutorial.

Good Luck!
