17:55? Log-likelihood derivation 21:50 Parameterize f theta or f inverse theta 28:50 Desiderata, Jacobians of special structure for fast determinant computation, lower triangular matrix determinant is product of diagonal elements 33:00? Derivation of Jacobian (simple layered coupling) 36:55 Simple layered coupling model is already able to map a complex distribution over pixels to a Gaussian (volume preserving) 42:00? Derivation of Jacobian (layered coupling with scaled shifts) 45:30? Generation process is deterministic 47:20 Sample data to get z, interpolation of z generates interpolated samples. Proves that while z are not compressive, they are meaningful latent representations. 50:00? Flow interpretation of autoregressive gaussian model 56:00? Inverse mapping computed in parallel 56:30? Jacobian lower diagonal because x_i only depends on z_
