Future Plans

I have been given the oppurtunity to present this work at LISEF and various science research fairs in the near future as part of my science research class. Additionally, I am considering submitting this work to a journal for publication. As for the project itself, I will be working on improving the model by creating a simulated dataset to add to the existing dataset of real exoplanet data. Furthermore, I am thinking about using a transfer learning approach by repurposing AstroNet for exoplanet companion identification with radial velocity. Keep following this directory for updates on this project.
