this stuck in is very an advanced topic so try to to make simple models simple models will also work and to help you to get a gold medal don't understa mage the power of neural networks even on tabular data mostly on tabular data people try to use only gradient boosting decision trees because they are so powerful moral networks can be as good as present boosting decision trees if you are able to come up with a good architectures and it will also help you your final ensemble if you are working with two models right inputs
