Input and output projectors (Kamath Eq 9.3, 9.19)

Input and output projectors (Kamath Eq 9.3, 9.19)

Usage

morie_kamath_ch9_input_projector(F_X, in_align = NULL)

morie_kamath_ch9_output_alignment(S_X, out_align = NULL)

Arguments

F_X

Modality features.

in_align

Matrix or function.

S_X

Signal tokens.

out_align

Matrix or function.

Value

List with estimate, prompts, shape.

Details

The two Python modules are the same linear map in opposite directions: km131 -> morie_kamath_ch9_input_projector (P_X = IN_ALIGN(F_X)), km147 -> morie_kamath_ch9_output_alignment (H_X = OUT_ALIGN(S_X)). Both accept a matrix (right-multiplied) or a function.

Examples

morie_kamath_ch9_input_projector(matrix(c(1, 2), 1), in_align = diag(c(1,
    2)))
