Hi! Well finally there is the first release of this project: A open source book which will hopefully contain some useful resources for those who want to learn some data analysis/machine learning.
This release covers a little of data preparation, data profiling, selecting best variables (DataViz), assessing model performance, and coming soon a case study using decision trees.
An intuitive and practical approach to data analysis, data preparation and machine learning, suitable for all ages! ?
