Run template codes

In this repository, we provide four template scripts:

(1) temp_01_gen_sample_from_INSTANCE
generate some samples using Earthquake Early Warning Augmentation (EEWA) and Marching Mosaic Waveform Augmentation (MMWA) using INSTANCE dataset.

cd temp_01_gen_sample_from_INSTANCE
bash auto_implement.sh

(2) temp_02_model_pretrain
fine-tune the trained model using few samples generated in temp_01_gen_sample_from_INSTANCE

cd temp_02_model_pretrain
python P01_train_REDPAN_dwa.py

(3) temp_03_continuous_predict
process continuous data using Seismogram-Tracking Medium Filter (STMF) 

cd temp_03_continuous_predict
python P01_continuous_pred.py

(4) temp_04_realtime_predict
triggering P arrivals using information-clipped earthquake waveform, simulating the conditions of real-time data processing.

cd temp_04_realtime_predict
python P01_rt_pred_tflite.py
