What did you do on YOUR summer holiday?
Sisilia Sinaga is a senior at BASIS Flagstaff who spent her summer as a volunteer intern at the USGS Astrogeology Science Center in Flagstaff. Sisilia has a head start on her senior project focusing on her keen interest in artificial intelligence and neural networks. Alicia Vaughan, the Director of Student Affairs at BASIS, partnered Sisilia with her mentor Dr. Ryan Anderson at the Astrogeology Science Center. Because Sisilia already has a strong math and coding background, she was able to step into one of Dr. Anderson’s projects with the Mars Curiosity Rover.
Ryan and Sisilia are using PySAT (Python Spectral Analysis Tool), a program that Ryan is developing to analyze spectra like those returned by the ChemCam instrument on the Curiosity Mars Rover. ChemCam shoots a laser at rocks and soil on Mars, breaking them down into a spark of plasma. The spectrum of light emitted from the spark contains a fingerprint of the chemical elements in the target. Sisilia is working on using neural networks to more accurately read that spectral fingerprint and dete4rmine the chemistry of the rocks and soils of Mars.
Neural python is the language within python that uses a library called TensorFlow™ to create neural networks. TensorFlow's website states that it was originally developed by researchers and engineers working on the Google Brain Team within Google's Machine Intelligence research organization for the purposes of conducting machine learning and deep neural networks research, but the system is general enough to be applicable in a wide variety of other domains as well.
Artificial neural networks (ANN's) are computing systems inspired by organismal nervous systems. Useful in image recognition ANN's can learn to identify images that contain a specific mineral by analyzing example images that have been previously labeled with that mineral.
Sisilia's biggest passions are computers, engineering, physics, astronomy, and math. She loves to program and write code in her free time. She is in her school's robotics club and participates in FTC competitions. She is also in the National Honor Society and volunteered with STEM City to assist students. Her first challenge was to fix the earthquake simulator at Killip Elementary School! You can see, via this video from Killip, that she was successful!
We wish Sisilia every success as she continues her senior project and pursues being accepted by her preferred university!
Thank you Sisilia for all you have done to advance STEM in STEM City!
