Kiri L. Wagstaff

My background is in Computer Science, Planetary Science, and Geology. I am most interested in problems that lie at the interfaces between these fields, such as automated methods (artificial intelligence, machine learning) to investigate science questions using planetary data (orbital and in situ).

I worked at the Jet Propulsion Laboratory in Pasadena, CA, as a researcher in the Machine Learning and Instrument Autonomy Group, investigating ways that machine learning can be used to increase the autonomy of space missions (2003 to 2022). My other roles at JPL include serving as a tactical planner and uplink lead for the Mars Exploration Rover Opportunity (2013 to 2017) and the PDS Imaging Node Technologist (2018 to 2022).

I've also conducted research and taught classes in Computer Science at Oregon State University.

My research projects at JPL have included:

• Onboard science for Europa Clipper: Developing and testing methods to quickly analyze data as it is collected during a flyby of Europa to assign high downlink priorities to the most scientifically valuable observations and to enable cross-instrument collaboration
• Mars Target Encyclopedia: Information extraction from scientific publications for planetary science
• V-FASTR: Efficient machine learning to detect transient radio phenomena (e.g., pulsars and Fast Radio Bursts) in real time
• Collaborative machine learning for sensor networks
• Automatic landmark identification and change detection in Mars orbital images (dark slope streaks, dust devil tracks, etc.)
• Analyzing the sensitivity of machine learning algorithms to high-radiation environments
• Predicting county-level crop yield from Earth orbital images
• Modeling user preferences for sets, rather than individual items (like music playlists or rover image downlink sets)
• Modeling flight software with state charts and using automatic code generation to convert them into C/C++ (for implementation) or Promela (for model checking)
• Tracking the north polar ice caps (water and CO₂) on Mars

News and upcoming events:

• I was elected a Fellow of the Association for the Advancement of Artificial Intelligence (AAAI) in 2023 for "significant contributions to deployed AI systems in NASA ground and spacecraft operations, AI education, and clustering algorithms."
• The video for my controversial ICML 2012 talk is no longer available (lost in a server crash). However, you can read the original paper: Machine Learning that Matters (pdf, 6 pages, 234K) and see the slides from a subsequent invited AAAI talk: Challenges for Machine Learning Impact on the Real World (1.6M).
• Interview with the How to Do Grad School podcast: Why We Learn, How to Write, & Fostering Collaboration (August 2021)

  • Hidden Heterogeneity: When to Choose Similarity-Based Calibration.
    Kiri L. Wagstaff and Thomas G. Dietterich.
    Transactions on Machine Learning Research, 2023.
    • We developed a method to calibrate classification predictions by leveraging similarity in feature space. This approach can particularly benefit subpopulations within the data set.
• All publications

• Automated Classification to Improve the Efficiency of Weeding Library Collections.
  Kiri L. Wagstaff and Geoffrey Z. Liu.
  Journal of Academic Librarianship, 44(2), p. 238-247, 2018.
  • We evaluated several machine learning classifiers in terms of their ability to predict which books are most likely to be weeded from a collection. We applied this method to a collection of more than 80,000 items from an academic library and found statistically significant agreement (p = 0.001) between classifier and librarian decisions.
• Marginalia in the digital age: Are digital reading devices meeting the needs of today's readers?
  Melanie Ramdarshan Bold and Kiri L. Wagstaff.
  Library & Information Science Research, 39(1), 16-22, 2017.
  • We surveyed readers to find out about their attitudes toward marginalia, and whether and how often they indulged in it themselves. We also investigated whether marginalia translates into electronic books and which features are most desired by users of e-readers.
