“…Most of the techniques employed the transfer learning mechanism using the pre-trained models. All the above methods [ 1 , 2 , 5 – 8 , 13 , 20 – 22 , 27 , 28 , 31 , 32 , 45 , 47 , 49 , 56 – 58 , 62 , 65 , 67 , 69 , 73 – 75 , 77 , 79 , 83 ] were focused on automatic lung disease classification using chest X-ray images. Despite promising outcomes of such CAD systems, some challenges are still unaddressed for the chest X-ray image-based lung disease classification.…”
