# Batch Normalization

BatchNorm is a compact paper for learning how activation statistics, optimization stability, and architecture design interact. It is a good bridge between practical deep learning and the math of normalization.

## Paper details

- Authors: Ioffe and Szegedy

- Venue: ICML 2015

- Track: ML Math

- Difficulty: Medium

- Reading time: 35 min

- Original paper: https://arxiv.org/abs/1502.03167

## What you will learn

- Why unstable activation distributions can make optimization harder.

- How learned scale and shift keep normalization from removing capacity.

- Why training-time statistics and inference-time statistics differ.
