 ## Workflow
 UP2ME is a general-purpose framework for Multivariate Time Series Analysis. It conducts taskagnostic pre-training when downstream tasks are unspecified. Once the task and setting (e.g. forecasting length) are determined, it gives sensible solutions with frozen pre-trained parameters. Further accuracy is achieved through multivariate fine-tuning.

 2. Download the datasets from [UP2ME-datasets](https://drive.google.com/file/d/1oLYcQa7NJcMDSP_rYSkP5hQHzXL2rpZM/view?usp=drive_link) and unzip it into the folder `datasets` in the root folder. The struture should be like:
 
-    - datasets
-      - ETT
-        - ETTm1.csv
-      - ...... same for csv format datasets: weather, ECL(Electricity) and traffic
-      - SMD
-        - SMD_train.npy
-        - SMD_test.npy
-        - SMD_test_label.npy
-      - ...... same for npy format datasets: PSM, SWaT and NIPS_Water(GECCO)

 3. We have already put the pre-trained model for each dataset in `./pretrain-library`. To get forecasting results on ETTm1, run:
     ```
     bash scripts/forecast_scripts/ETTm1.sh
     ```
-    the immediate reaction(UP2ME(IR)) and fine-tuning(UP2ME(FT)) modes  will be tested on 4 different forecasting lengths (96, 192, 336, 720) and results will be saved in a new folder `./forecast_result`.

 4. To reproduce results for all 3 tasks on all 8 datasets, run other scripts in `./scripts`.
