Research foundations in decision-making, learning, perception, and computational methods across the SOS+CD publication archive.
What can learning and decision-making teach us about scientific work?
The archive includes earlier work by lab members on cognition, learning, and computational methods. These studies provide context for questions about how people and models learn, evaluate evidence, and act under uncertainty.
Learning the problem itself
Decision-making requires more than choosing the best action under a known model. Our structure-learning work asks how people infer the environment that produces rewards and how this changes the interpretation of their choices.
Models as explicit assumptions
A model makes assumptions about information, uncertainty, and objectives. Studies of Bayesian decision theory and reinforcement learning make those assumptions inspectable and explore the behavior they imply.
Methods across the archive
Related publications cover perception, motor learning, statistical models, and scientific text and image representations. This is a historical research thread; the archive preserves the dates and contexts of those contributions.
An open question
Which assumptions about a learner's knowledge change our judgment of whether a choice or model behavior is appropriate?
Behavior that looks inefficient under a fixed model can make sense when a person is also learning how the environment works. This study connects human choices in sequential reward tasks with Bayesian models that learn both rewards and the structure that generates them.
A study's chance of being correct is only one part of deciding whether a research program is worth pursuing. This paper develops a decision-theoretic framework that makes potential costs and benefits explicit.
MISTI learns joint representations of scientific figures, captions, and publication metadata. The study tests whether contextual information such as titles, sections, and concepts improves retrieval beyond the image-caption pair alone.
