The Age of Robotics
“If every tool, when ordered, or even of its own accord, could do the work that befits it... If the weavers' shuttles were to weave of themselves, then there would be no need either of apprentices for the master workers or of slaves for the lords.”
Aristotle, “De Republica Atheniensium”, ~322 BC

Sounds and Prior Information
What about the rest?

Prior Information is Key
Only 10% of the inputs into primary visual cortex come from the retina via the lateral geniculate nucleus. The rest come from higher visual and frontal areas.
Perception can also be modified by attention.
Thus the brain can actively focus on relevant information.

The Brain Models its Environment
The frontal regions of the braincreate models of the world basedon prior experience. Thesemodels affect perception and attention.
In addition, the brain modelsitself.
Experiments in multi-sensoryprocessing has shown thatthe information processing is consistent with Bayes Theorem

Thinking Machines
Your frontal lobes carry a model of yourself that is continually updated from data received from a dense sensor network. This implements both ‘Instrument Health Monitoring’ and ‘Calibration’
You learn from new data by updating your model of the world.
You actively seek new data by asking relevant questions.

Intelligent Autonomous Instruments
Require:
Stability Control
Instrument Health Monitoring
Automated Calibration
Accurate Onboard Data Analysis
Adequate Data Coverage
Ability to Actively Seek Data
2 May 2008 Kevin H Knuth NTIR 2008
Novel Instrument Design
To accomplish these goals, these novel instruments must
Monitor their own state (health and calibration) Infer their state from self-sensing Be equipped with dense sensor networks Infer calibration parameters
Learn from data Make inferences from data Perform hypothesis testing
Ask new questions Actively seek new data Select optimal experiments

'Am I already in the shadow of the Coming Race? and will the creatures who are to transcend and finally supersede us be steely organisms, giving out the effluvia of the laboratory, and performing with infallible exactness more than everything that we have performed with a slovenly approximativeness and self-defeating inaccuracy?'
George Eliot (Mary Anne Evans),
The Impressions of Theophrastus Such, 1879.
