func (g *FlowGenerator) affineTransform(x []float64, flowIdx int, inverse bool) ([]float64, float64) · Forward: y2

Read the equation

This relation defines Forward: y2 in the source section “func (g *FlowGenerator) affineTransform(x []float64, flowIdx int, inverse bool) ([]float64, float64) · Forward: y2”. Applies an exponential factor. The exponent determines its real scaling or, for a complex exponent, its phase. Its interpretation depends on the source’s stated variables and conditions; this record does not assign an unprovided physical or cognitive meaning to them.

Terms & definitions

The recovered passage does not supply a separate symbol table. Read the source context for the notation used in this version; familiar letters may carry different meanings in other builds.

How it works

1. Read Forward: y2 as the quantity being defined or updated by this relation.

2. Applies an exponential factor. The exponent determines its real scaling or, for a complex exponent, its phase.

3. Use this version’s variable definitions and update order. The same symbol may be assigned a different meaning in another build.

Assumptions & limits

• This source expression was recovered from the pinned code revision. Its presence does not establish that the associated program was built, run, or scientifically validated.

Original context

	// Apply transform
	y := make([]float64, dim)
	logDetJac := 0.0

	copy(y[:halfDim], x1)

	if !inverse {
		// Forward: y2 = x2 * exp(s(x1)) + t(x1)
		for i := 0; i < halfDim; i++ {
			y[halfDim+i] = x2[i]*math.Exp(scale[i]) + shift[i]
			logDetJac += scale[i]
		}
	} else {
		// Inverse: x2 = (y2 - t(x1)) * exp(-s(x1))
		for i := 0; i < halfDim; i++ {
			y[halfDim+i] = (x2[i] - shift[i]) * math.Exp(-scale[i])
			logDetJac -= scale[i]
		}

Forward: y2 = x2 * exp(s(x1)) + t(x1)
