Extracting parameters

You've now tested 192 different models on the msd dataset, and you found the best ROEM and its respective model (model 38).

You now need to extract the hyperparameters. The model_list you created previously is provided here. It contains all 192 models you generated. Use the instructions below to extract the hyperparameters.
