GINI Impurity: The general form of GINI impurity isI=∑mi=1fi⋅(1−fi)I=∑i=1mfi⋅(1−fi) Thoughts: Splitting is done on a measure of impurity. High "purity" is likely the same as low entropy. The approach is likely related to entropy minimization. ...
The discriminatory power of the model is normally quantified with Somers' D which is the same as Gini in the binary context. $Gini = 2 \times AUC -1$ AUC is also nicely explained here: https://developers.google.com/machine-learning/crash-course/classification/roc-and-auc#...

After five years wearing the Liverpool shirt,Gini Wijnaldumis no longer a Red after agreeing to join PSG – and he’s already showing what we will miss. The writing was on the wall over the future of the Dutchman for much of the season, with no progress on contract talks ...
If we can equate income, the Gini coefficient will be smaller. The relevant organizations of the United Nations stipulate that if the average income is below 0.2, the average income is highly averaging; 0.2 to 0.3 means a relatively average; 0.3 to 0.4 is relatively reasonable; 0.4 to 0.5 ...
This seems like an incredibly difficult thing to measure -- I mean, there are simply so many different factors to take into consideration. With all these different variables, is income equality really a strong indicator, statistically? WiseGeek, in your inbox ...

Montillo then goes into some practical considerations, e.g., how are splits chosen (squared error, gini index), how many trees to build (build trees until error no longer decreases), or how to selectkatex is not defined(use the recommended defaults ofkatex is not definedfor regression and...
It is a data-driven technology. Machine learning is much similar to data mining as it also deals with the huge amount of the data. Need for Machine Learning The demand for machine learning is steadily rising. Because it is able to perform tasks that are too complex for a person to direct...
