“You learn from your mistakes”
🇬🇧 You learn from your mistakes
🇻🇦 Errando discitur
🇮🇹 Sbagliando si impara
🇩🇪 Aus Fehlern lernt man
🇪🇸 Echando a perder se aprende
🇯🇵 七転び八起き — Fall 7 times, stand up 8
🇨🇳 失败是成功之母 — Failure is the mother of success
But guess who takes this more literally than anyone? Machine Learning algorithms.
MAKING MISTAKES…
The algorithm makes a prediction and calculates how wrong it was:
L = 1/n ∑(y − ŷ)²
Translation: how far off were you from the right answer? Square it so it hurts even more. 😅
…AND LEARNING!
Parameters are adjusted in the direction that reduces the error:
θ = θ − η ∂L/∂θ
Translation: ok, next time I’ll correct a little. η is “how much” I correct.
🔁 REPEAT a few million times.
From Neural Networks to Gradient Boosting, from Linear Regression to SVMs, the core idea is the same: measure your mistake, learn from it, try again.
A universal principle, from ancient proverbs to artificial intelligence.
