[Verse 1]
Started with a dataset, chaos everywhere
Need to build a tree that's clean and fair
ID3 algorithm, that's my first choice
Information gain becomes my voice
Split the data by the best attribute
Entropy measures help me compute
Which feature gives the purest separation
Building branches through calculation
[Chorus]
Information gain, entropy's the game
Split and conquer, never stays the same
ID3 to C4.5, keep the tree alive
Prune the branches, make the model thrive
Gain ratio, missing values too
Decision trees know what to do
From root to leaf, the path is clear
Algorithm power, crystal clear
[Verse 2]
Entropy formula in my mental space
Negative sum of p times log base
Calculate for every single class
Information theory helps me pass
Pick the attribute with highest gain
Split the dataset, break the chain
Recursive calls until we're done
Pure leaf nodes, victory won
[Chorus]
Information gain, entropy's the game
Split and conquer, never stays the same
ID3 to C4.5, keep the tree alive
Prune the branches, make the model thrive
Gain ratio, missing values too
Decision trees know what to do
From root to leaf, the path is clear
Algorithm power, crystal clear
[Verse 3]
C4.5 stepped up the game real strong
Fixed the problems that went wrong
Gain ratio beats the bias issue
Continuous values, we can use you
Missing data, no more stress
Probabilistic splits, nothing less
Post-pruning keeps overfitting away
Error-based reduction saves the day
[Bridge]
From Shannon's wisdom to Quinlan's mind
Information theory perfectly designed
Gini impurity, another way to measure
Decision boundaries, algorithmic treasure
[Chorus]
Information gain, entropy's the game
Split and conquer, never stays the same
ID3 to C4.5, keep the tree alive
Prune the branches, make the model thrive
Gain ratio, missing values too
Decision trees know what to do
From root to leaf, the path is clear
Algorithm power, crystal clear
[Outro]
Recursive splitting, top to bottom flow
Decision trees help knowledge grow
From ID3 foundations to C4.5 evolution
Machine learning's perfect solution
