Usage

morie_geron_gru(x_t, h_prev, weights)

Arguments

x_t: Input vector.
h_prev: Previous hidden state.
weights: Named list with W_z,U_z,b_z,W_r,U_r,b_r,W_h,U_h,b_h.

Value

List with h_t, z_t, r_t, h_tilde, estimate, n, method.

Examples

W <- list(W_z = matrix(0, 2, 2), U_z = matrix(0, 2, 2), b_z = c(0,
    0), W_r = matrix(0, 2, 2), U_r = matrix(0, 2, 2), b_r = c(0,
    0), W_h = matrix(0, 2, 2), U_h = matrix(0, 2, 2), b_h = c(0,
    0))
