Unbeatable baseline: Nearest-neighbor algorithm. Often, when you are trying to write a paper, you want to show that “your cuve is better than my curve”.

Scientists in Iraq used a k-Nearest Neighbors algorithm to evaluate the operational status of PV modules under various conditions, including partial shading, open circuit, and short circuit ...

But the logic to convert gesture to control signals is all Vectron, and uses a k -nearest neighbor algorithm executed in 6502 assembly.
