Helping machine learning models identify objects in any pose

Posted by in categories: information science, robotics/AI, space

A new visual recognition approach improved a machine learning technique’s ability to both identify an object and how it is oriented in space, according to a study presented in October at the European Conference on Computer Vision in Milan, Italy.

Self-supervised learning is a machine learning approach that trains on unlabeled data, extending generalizability to real-world data. While it excels at identifying objects, a task called semantic classification, it may struggle to recognize objects in new poses.

This weakness quickly becomes a problem in situations like autonomous vehicle navigation, where an algorithm must assess whether an approaching car is a head-on collision threat or side-oriented and just passing by.

ORNL researchers translate foundational uranium science into active nonproliferation solutions

Posted by in categories: biotech/medical, computing, military, nuclear energy, science, terrorism

Through its commitment to international nuclear nonproliferation — a mission focused on limiting the spread of nuclear weapons and sensitive technology while working to promote peaceful use of nuclear science and technology — the United States maintains a constant vigilance aimed at reducing the threat of nuclear and radiological terrorism worldwide.

With extensive research into both basic and applied uranium science, as well as internationally deployed operational solutions, the Department of Energy’s Oak Ridge National Laboratory is uniquely positioned to contribute its comprehensive capabilities toward advancing the U.S. nonproliferation mission.

In 1943, seemingly overnight, ORNL emerged from a rural Tennessee valley as the site of the world’s first continuously operating nuclear reactor, in support of U.S. efforts to end World War II. ORNL’s mission soon shifted into peacetime applications, harnessing nuclear science for medical treatments, power generation and breakthroughs in materials, biological and computational sciences.

Hubble trouble or Superbubble? Astronomers need to escape the ‘supervoid’ to solve cosmology crisis

Posted by in category: cosmology

The disagreement in the rate of expansion of the universe, the Hubble tension, could arise from the fact Earth sits in an under-dense supervoid region of space.
