Jamie Ryan Kiros coauthored the 2016 layer normalization paper with Jimmy Lei Ba and Geoffrey E. Hinton. The original paper gives the full byline Jamie Ryan Kiros and a University of Toronto affiliation. Its normalization statistics are computed across the inputs within one case, rather than across different cases in a batch.^[ref]

A small original implementation experiment tests that distinction without measuring training speed. Fix one case's two inputs at $h=(2,6)$, unit gains, zero biases and a variance stabilizer of $1$. The within-case mean is $4$ and variance is $4$, so its normalized outputs areEvaluate this case first beside another case $(-100,100)$ and then beside $(1000,2000)$. The stated isolated normalization computation returns the same output for $h$ in both evaluations, because neither companion enters its statistics. This tests a concrete dependency of the computation, not a claim about every layer of a complete network.

The paper also studies recurrent neural networks, computing the statistics separately at each time step.^[ref] That application makes the choice of averaging axes consequential. The paper establishes a collaborative contribution; its byline does not assign a separate invention to each author.
