Introduced by Diederik P. Kingma et al. in Glow: Generative Flow with Invertible 1x1 Convolutions

archive 2025-07-28 Description, source and code snippet are the archive's method entry.

The Invertible 1x1 Convolution is a type of convolution used in flow-based generative models that reverses the ordering of channels. The weight matrix is initialized as a random rotation matrix. The log-determinant of an invertible 1 × 1 convolution of a h ×w ×c tensor h with c ×c weight matrix 𝐖 is straightforward to compute:

log| det((dconv2D(𝐡;𝐖))/d𝐡) | = h ·w ·log| det(𝐖) |

Papers per year the archive tags with this method, by the paper's archive date (79 dated). Bars are counts, not a trend claim.

Components: the archive holds no method-to-method composition, so PwC's Components table cannot be rebuilt; the Papers list carries no Results column for the same reason (the archive does not join its leaderboard rows to method tags).
