Extended Histogram-based Outlier Score (EHBOS)
In this paper, we propose the Extended Histogram-Based Outlier Score (EHBOS), which enhances HBOS by incorporating two-dimensional histograms to capture dependencies between feature pairs. This extension allows EHBOS to identify contextual and dependency-driven anomalies that HBOS fails to detect.
Machine Learning for Planetary Rovers
Advanced autonomy must be incorporated into future rovers to transition performance-limiting human-driven operations into safe and reliable autonomous capabilities running on-board the rover. This chapter describes several algorithms developed at the Jet Propulsion Laboratory to investigate such autonomy from the perspective of vision-based traversability assessment for safe navigation and scientific scene interpretation..
