self_loop!

ReservoirComputing.self_loop! — Function

self_loop!([rng], reservoir_matrix, weight; signs = nothing)

Adds jumps to a given reservoir_matrix with chosen weight and determined jump_size. weight can be either a number or an array.

Arguments

rng: Random number generator. Default is Utils.default_rng() from WeightInitializers.
reservoir_matrix: matrix to be changed.
weight: weight to add as a self loop. Can be either a single number or an array.

Keyword arguments

signs: Controls sign flips. Use RandomSigns, RegularSigns, or IrrationalDigitSigns. Pass nothing to leave signs unchanged. Default is nothing.

Examples

julia> matrix = zeros(Float32, 5, 5)
5×5 Matrix{Float32}:
 0.0  0.0  0.0  0.0  0.0
 0.0  0.0  0.0  0.0  0.0
 0.0  0.0  0.0  0.0  0.0
 0.0  0.0  0.0  0.0  0.0
 0.0  0.0  0.0  0.0  0.0

julia> self_loop!(matrix, 1.0);

julia> diag(matrix) == fill(1.0f0, 5)
true
