Dear Competitors,
We have updated our Starting Kit introducing the following features:
Helper scripts:
Considering the number of individual predictions that are required to collect for a leaderboard submission, we now provide the following helper scripts:
– mk_pred_core.sh – to create predictions for the Core and Nowcasting leaderboards
– mk_pred_transfer.sh – – to create predictions for the Transfer Learning leaderboard
Those scripts can be used to generate and compile all individual predictions from a single model. Please note that the helper scripts are using config_baseline_w4c23-pred.yaml file to generate a submission file. We refer you to the GitHub READ.me to learn how to use the helper scripts.
8-hours vs 4-hours predictions:
The Nowcasting and Transfer Learning leaderboards accept submissions for 4 hours into the future, and the Core Leaderborad accepts submissions 8 hours into the future. You can now use our Starting Kit code to train the UNET-3D baseline model both for 4-hours and 8-hours leaderboards. In order to do so, just simply set up the len_seq_predict parameter in config_baseline_w4c23.yaml file to:
– len_seq_predict: 16 – for 4 hours prediction
– len_seq_predict: 32 – for 8 hours prediction
In case you would like to use our helper scripts to generate the submission, please remember to set up correctly len_seq_predict parameter also in the config_baseline_w4c23-pred.yaml file.
Mapping the radar values lower than 0.2 to zero:
This is configured by the following mapping in the config_baseline_w4c23.yaml:
map: [[lessthan0.2, 0], [-8888000.0, 0], [-9999000.0, 0], [inf, 0], [nan, 0]]
If you would like to test our new features, please download the latest version of the Kit from our GitHub repository!
