Impact of Learning Rate, Optimizer, Learning Rate Scheduler and Batch Size on OOD generalization in Deep learning

This repository is for the project of Optimization for ML course by Prof. Sebastian Stich at Saaralnd University.

For the code reproducibility:

1. Run data_setting_notebook.ipynb which will download data and then arrange the files accordingly as required by the training code. Please take note of the dependencies and install them accordingly. Basically you require the zipfile, pathlib, shutil as dependencies for this part.

2. Once the first part is completed, just run the main.py using the command python main_check.py -bt=128 -opt='ADAM' -lrn_rt=1e-2 -ep=50 -schdlr='step_lr' . Things to keep in mind here: bt: batch size. For this experiment we have used 64 and 128 opt: optimizer. For this experiment we have used ['ADAM', 'SGD', 'RMSPROP', 'ADAMW']. Please select from this list only and pass lrn_rt: learning rate. Please select from [1e-2,1e-4] ep: epoch schdlr: Learning Rate scheduler. Need to select from ['none','step_lr']

3. To plot the curves: run python plotting_curves.py -lrn_rt=1e-4 . lrn_rate: Learning rate . Please select lr from [1e-2,1e-4]

NB: All the train and validation results obtained during training have been uploaded in the ./logs folder.
