singular_spectrum

Build U @ diag(singular_values) @ V.T from independent Haar factors.

from resdag.layers import ESNLayer

reservoir = ESNLayer(500, feedback_size=3, recurrent_initializer='singular_spectrum', spectral_radius=None, seed=7)
parameter default
singular_values None
dtype torch.float32
device None

Override parameters with recurrent_initializer=("singular_spectrum", {...}) or pre-configure with get_recurrent_initializer("singular_spectrum", ...). The existing topology= spelling and get_topology() also work.

This builder preserves its native spectrum/scale by default. Use its parameters to control that scale, or explicitly configure get_recurrent_initializer(..., rescale=True) to allow an outer radius rescale.
