Problem: Overfitting
Cause: Model learns noise, not signal
Fix: Regularization (LASSO, Ridge, Elastic Net)
Penalize complexity. Force the model to be selective.

the umbra of a shadow is not just "take a slice of the shadowing object and draw that on the other side" unless you're making a videogame
light is WEIRD
eg:
Perhaps you are overfitting ai to explain all manipulated media?
Perhaps you are overfitting ai to explain all manipulated media?
Where would you look first: data quality, execution costs, market-regime change, or overfitting?
I am curious how people prioritize those when the P&L starts diverging.

Here’s your cheat sheet:
Problem : Spurious signals
Fixes: FDR, Bonferroni, feature selection
Problem: Overfitting
Fixes:LASSO, Ridge, cross-validation
Problem: Poor generalization
Fixes: Replication, simpler models
