Why Your Classifier Trains So Slowly at First (and MSE Might Be Why)
A classification model that’s confidently wrong early in training can get an almost nonexistent correction signal if you’re using the wrong loss function. Here’s the exact mechanism, measured, and why…

Why Your Training Loss Exploded to NaN: The Math of Learning Rate, Not Guesswork
A loss curve that spikes to NaN mid-training isn’t random instability — it’s a provable consequence of crossing an exact convergence threshold. Here’s the derivation, and what it means for…
