In statistics, classification is defined as the categorization of given objects (observations) into two or more types.
According to Nasa's Near-Earth Object Observation Programme, an asteroid like 2012 DA14 flies this close on average only once every 40 years – although it will still be some 17,100 miles above our heads.
So let's resort to a neutral term that links subject and object: observation.
In 2016, the Near Earth Object Observation program was folded into a newly created Planetary Defense Coordination Office, which is overseen by Johnson.
Enter Lindley Johnson, a former member of the Air Force's space surveillance team and, for several years, the sole member of NASA's Near Earth Object Observation program, which is responsible for tracking and cataloging large asteroids in our solar system.
Behaviourally, it has been hypothesized that, in a way analogue to that of monkey visuomotor 'canonical' neurons [39] which respond during object grasping and object observation, olfactory information may indeed contain both the 'olfactory' representation of an object and the motor representation of the most suitable hand/finger interaction with it.
"Although they wouldn't cause a global catastrophe if they impact the Earth, they still do a lot of regional destruction," said Lindley Johnson, who oversees the Near-Earth Object Observations Programme at Nasa headquarters in Washington DC.
Funds for near-Earth object observations would quadruple to $20.4 million.
Finally, the occlusion landscape allows the tracker to predict the complete or partial occlusion of object observations.
Because of incomplete knowledge due to unknown objects and occlusions in visual observations, object observations are imperfect and action success is uncertain, making planning challenging.
