Learning Seasonal Phytoplankton Communities with Topic Models
Arnold Kalmbach, Heidi M. Sosik, Gregory Dudek +1
In this work we develop and demonstrate a probabilistic generative model for phytoplankton communities. The proposed model takes counts of a set of phytoplankton taxa in a timeseri…
Feature discovery and visualization of robot mission data using convolutional autoencoders and Bayesian nonparametric topic models
Genevieve Flaspohler, Nicholas Roy, Yogesh Girdhar
The gap between our ability to collect interesting data and our ability to analyze these data is growing at an unprecedented rate. Recent algorithmic attempts to fill this gap have…
Near-optimal irrevocable sample selection for periodic data streams with applications to marine robotics
Genevieve Flaspohler, Nicholas Roy, Yogesh Girdhar
We consider the task of monitoring spatiotemporal phenomena in real-time by deploying limited sampling resources at locations of interest irrevocably and without knowledge of futur…
Phytoplankton Hotspot Prediction With an Unsupervised Spatial Community Model
Arnold Kalmbach, Yogesh Girdhar, Heidi M. Sosik +1
Many interesting natural phenomena are sparsely distributed and discrete. Locating the hotspots of such sparsely distributed phenomena is often difficult because their density grad…
