The evaluation of mass composition of cosmic rays in the knee region (\∼\n3 PeV) is critical to understanding the transition in the origin of cosmic\nrays from galactic to extragalactic sources. The IceCube Neutrino Observatory\nat the South Pole is a multi-component detector consisting of the surface\nIceTop array and the deep in-ice IceCube detector. By applying modern\nmachine-learning techniques to cosmic-ray air showers reconstructed\ncoincidentally in both detector components of IceCube observatory, the energy\nand the mass of primary cosmic rays in this transition region can be measured.\nIn this contribution, we will discuss the reconstruction performance and\ncomposition sensitivity of IceCube observables presently under development.\n
