MVP: Unified Motion and Visual Self-Supervised Learning for Large-Scale Robotic Navigation

1 code implementation2 Mar 2020 Marvin Chancán, Michael Milford

Our experimental results, on traversals of the Oxford RobotCar dataset with no GPS data, show that MVP can achieve 53% and 93% navigation success rate using VO and RO, respectively, compared to 7% for a vision-only method.

A Hybrid Compact Neural Architecture for Visual Place Recognition

1 code implementation15 Oct 2019 Marvin Chancán, Luis Hernandez-Nunez, Ajay Narendra, Andrew B. Barron, Michael Milford

State-of-the-art algorithms for visual place recognition, and related visual navigation systems, can be broadly split into two categories: computer-science-oriented models including deep learning or image retrieval-based techniques with minimal biological plausibility, and neuroscience-oriented dynamical networks that model temporal properties underlying spatial navigation in the brain.

CityLearn: Diverse Real-World Environments for Sample-Efficient Navigation Policy Learning

1 code implementation10 Oct 2019 Marvin Chancán, Michael Milford

While deep reinforcement learning has shown success in solving these perception and decision-making problems in an end-to-end manner, these algorithms require large amounts of experience to learn navigation policies from high-dimensional data, which is generally impractical for real robots due to sample complexity.
