• /Dataset: Contains datasets for 6 time reasoning tasks, unified into a classification task format. Due to size limitations, RCW and ECG datasets are not included in this repository but will be made available in the final version through alternative means.
• /SupervisedModels: Contains supervised time series models used for comparison.
• /LLMs: Contains LLM-based methods, including traditional numerical modeling and the proposed VL-Time method.

Install the required libraries by running:

pip3 install -r ENV.txt

1. Navigate to the SupervisedModels directory:

   cd /SupervisedModels

2. Run experiments using scripts in the scripts folder. For example:

   bash Transformer.sh

   • Use --root_path to specify the dataset
   • Use --model to specify the model

1. Navigate to the LLMs directory:

   cd /LLMs

2. Set up API key:

   • Add your API key in /LLMs/Method/LMM.py
   • Specifically, set the openai_api_key

3. Prepare visualization data:

   • Place the visualization data in the LLMs/Dataset folder
   • Currently, data for visual modeling is provided

4. Run experiments:

   bash Scripts.sh

   • Set modal="L" for traditional numerical modeling
   • Set modal="V" for VL-Time visual modeling
   • Use --model to specify different LLMs
   • Set --num_shot_per_class=0 for zero-shot reasoning; use values >0 for few-shot setting
   • Use --hint="Please solve this problem step by step" for chain-of-thought reasoning
