Problems
Did not spend enough time working on tech day
COVID and lockdown disrupted the work flow for tech day
Team communication was below the level needed
ARFF and CSV
These are the file formats that are used when switching between Weka and Excel/google sheets
ARFF is the correct file format which is needed to open the file in Weka
CSV is the format which the file can be opened in either Excel or google sheets
Why use Weka?
Weka is free to use and offers free videos on how to use Weka
Weka offers datasets to experiment with, this allowed us to use these and understand Weka a bit better.
