SURF: Announcements of Opportunity
Below are Announcements of Opportunity posted by Caltech faculty and JPL technical staff for the SURF program. Each AO indicates whether or not it is open to non-Caltech students. If an AO is NOT open to non-Caltech students, please DO NOT contact the mentor. Announcements of Opportunity are posted as they are received. Please check back regularly for new AO submissions!
Remember: This is just one way that you can go about identifying a suitable project and/or mentor. Click here for more tips on finding a mentor. Announcements for external summer programs are listed here.
*Students applying for JPL projects should complete a SURF@JPL application instead of a "regular" SURF application.
*Students pursuing opportunities at JPL must be U.S. citizens or U.S. permanent residents.

Background: |
NOTE: This project is being offered by a Caltech alum and is open only to Caltech students. The project will take place at University of Newcastle Australia in Newcastle, Australia. See additional notes in last field below. Towards addressing the need of more interpretable models in AI, we started a collaboration that involved several Caltech SURF students in 2018, 2019, and 2020. In this work we have we pioneered the use of analytic continued fractions. As of January 2021, several publications have arising from the work with Caltech SURF students and some manuscripts have been accepted [1,2,3,4,5]. In addition, new manuscripts in areas such as nuclear physics [6,7], approximating unknown potentials given limited data [8], rock mechanics [9], and the famous Thomson problem [10] have been submitted and/or published. Links to these publications are available via searching for Prof. Moscato’s information in Google Scholar. What characterizes our work is to find good approximations but also that excel in generalization in extrapolation. This is indeed a project for pioneers in new techniques that deliver better generalization from limited number of examples. Students will explore the limitations of different machine learning regression methods and help to develop a new methodology based on analytic continued fractions. SURF Students will work in individual subprojects, but also as a team and potentially with other Caltech students still interested in the project, current postdocs and PhD students in Newcastle, and partners in Italy, Spain and Australia. |

Description: |
The student will continue the ongoing development of open source codes for memetic algorithms [3,11] for machine learning problems which it will be based on a representation that exploits the power of analytic continued fractions. In this particular project, the student will look at datasets of current interest to our group and we envision that we can also look at other datasets of interest of the student and/or collaborators of Caltech. The method will be tested with a number of datasets of interest and available for experimentation. A comparison with other machine learning approaches are expected, thus the deliverables may help the team to continue the collaboration after SURF and engage in ongoing competitions in international events dedicated to this area or those such as being sponsored by Kaggle and other international groups. We expect that candidates could continue developing this research area while returning to Caltech, if interested in developing an ongoing collaboration with the mentors (as it has happened in the past). The internship may provide the necessary time for effective communication of what the core problems are and find a first solution which may result in, at least, one journal publication. |

Student Requirements: |
High-level programming skills, interest in scientific computing/machine learning/artificial intelligence. Experience in HPC and GPU computing, knowledge of symbolic regression and its applications is also a plus. Additional Notes: Students will have access to the facilities of the NewSpace building located in front of it: https://www.newcastle.edu.au/about-uon/our-environments/new-space Some days of the week the students will also conduct their research at the Callaghan Campus of The University of Newcastle accompanying the mentors while they teach/research there. A shuttle exists allowing easy commute between the two campuses. Check out @mynewcastle or @pablomoscato on Instagram for photos of the city and its natural beauty. The NewSpace building is close to some beaches and attractions. A video of continued fractions for regression problems in physics can be found at Prof. Moscato’s YouTube channel. https://www.youtube.com/channel/UC10nC9lebye6tLm-xO2ASnw |
