We consider the geodesic motions in the Kerr-Sen-AdS$_4$ spacetime. We obtain the equations of motion for light rays and test particles. Using the parametric diagrams, we shown some regions where the radial and latitudinal geodesic motions are allowed. We analyse the impact of parameter related to dilatonic scalar on the orbit and find that it will result in more rich and complex orbital types.

DTG-FF reaches 91.8% on CIFAR-10 and 49.4% on ImageNet-100 224x224 but BP baselines beat it by 2.4-5.93 pp with gaps widening by class count on real data while reversing the synthetic trend.
