Run Sizey

  1. Create a Python virtual environment and install the dependencies
  2. Run python3 main.py filename alpha softmax error_metric seed [--use_online_grid]

Where:

  • filename describes the workflow from the data folder. For instance ./data/trace_methylseq.csv
  • alpha sets the alpha you want to execute Sizey with. It has to be between 0.0 and 1.0
  • softmax toggles the softmax ensemble strategy. Set to True to use it, otherwise False for the argmax strategy.
  • error_metric defines the XYZ used for ABC. Currently, it is either smoothed_mape or neg_mean_squared_error whereas smoothed_mape should be used and other error metrics might be experimental and change the impact on the RAQ score.
  • seed defines the seed for splitting up the initial data in training and test data and also defines the order of online task input.
  • --use_online_grid (optional) toggles the online grid search.

Here is an example command: ./data/trace_methylseq.csv 0.0 True smoothed_mape 1996

  • Check the results in terminal, and in results folder.
