Apple researchers propose MVICAD2 for multi-view ICA with delays and dilations

MVICAD2 extends multi-view ICA to allow sources to differ across subjects in both temporal delays and dilations, with identifiable sources and a closed-form likelihood approximation. Simulations show it outperforms existing multi-view ICA methods, and validation on the Cam-CAN dataset links delays and dilations to aging.
